Product details
Overview
PCM3060PWRG4 from Texas Instruments is a 24-bit asynchronous stereo audio codec with independent ADC and DAC blocks, supporting up to 96 kHz sampling on the ADC side and 192 kHz on the DAC side. It features differential analog outputs (8 Vp-p), 5-V analog / 3.3-V digital dual supplies, TSSOP-28 package, and integrated antialiasing/low-pass filters - deployed in DVD-RW, digital TV, and STB audio signal chains.
For engineers reviewing the PCM3060PWRG4 datasheet, PCM3060PWRG4 pinout, PCM3060PWRG4 application, or PCM3060PWRG4 equivalent, key selection criteria include asynchronous sample-rate independence, THD+N ≤ –94 dB (DAC, diff, 48 kHz), SNR ≥ 105 dB (DAC), I²C/SPI programmability, and hardware mode for minimal-control deployments.
Technical Context
The PCM3060PWRG4 implements separate delta-sigma modulators: a 64× decimation filter for the stereo ADC and 64×/128× interpolation for the stereo DAC. Its dual-system-clock architecture (SCKI1 for ADC, SCKI2 for DAC) enables true asynchronous operation - e.g., 44.1 kHz ADC input and 48 kHz DAC output simultaneously - with independent master/slave audio interface control per channel.
It supports three operational modes: software-controlled SPI/I²C (full register access), hardware mode (pin-strapped via MODE/MS/MD), and mixed-mode configuration. Digital audio formats include I²S, left-justified, and right-justified with 16-/24-bit word lengths and MSB-first, two's-complement data encoding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 24-bit delta-sigma with 64× decimation - delivers 99 dB SNR and –93 dB THD+N at 48 kHz, enabling high-fidelity digitization of line-level analog inputs. |
| DAC Resolution | 24-bit delta-sigma with 64×/128× interpolation - achieves 105 dB SNR and –94 dB THD+N (differential) at 48 kHz, suitable for premium audio playback paths. |
| Sampling Rates | ADC: 16–96 kHz; DAC: 16–192 kHz - supports legacy CD (44.1 kHz), DVD-Audio (96 kHz), and high-res streaming (176.4/192 kHz) without clock domain locking. |
| Analog Supplies | VCC = 4.5–5.5 V (analog), VDD = 2.7–3.6 V (digital) - separates noise-sensitive analog circuitry from digital switching domains for optimal dynamic range. |
| Audio Interface | I²S/left/right-justified, 16/24-bit, MSB-first - interoperable with standard DSPs, microcontrollers, and FPGA audio peripherals without format translation logic. |
| Power Dissipation | 220 mW typical (48 kHz full operation); 4.4 mW in full power-down - enables thermal management in compact AV enclosures and battery-backed standby states. |
| Package | TSSOP-28 (6.4 mm × 11.3 mm, 0.65 mm pitch) - surface-mount compatible with automated assembly and provides adequate thermal relief for sustained audio processing. |
Pinout & Package
TSSOP-28 package with exposed thermal pad (not electrically connected); 0.65 mm pitch, 6.4 mm × 11.3 mm body size; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AGND1 (23) | ADC analog ground | Reference return for ADC analog front-end - must be star-connected to AGND2 and VCOM to minimize crosstalk between ADC/DAC sections. |
| VOUTL+/VOUTL– (20/19) | DAC L-channel differential output | Provides 8 Vp-p balanced output; VOUTL– must remain open in single-ended mode - enables noise-immune routing to external amplifiers or transformers. |
| SCKI1/SCKI2 (6/9) | Independent system clocks | Accepts 2.048–36.864 MHz clocks for ADC/DAC respectively - allows fully asynchronous sample-rate conversion without PLL jitter accumulation. |
| MODE (28) | Operation mode selector | Quad-state input (VDD, DGND, pullup/pulldown) configures SPI/I²C/hardware mode - eliminates need for external mode-setting EEPROM or firmware bootload. |
| RST (15) | Active-low reset/power-down | Holding LOW for ≥2048/fS forces full power-down (780 µA); release initiates synchronized fade-in - ensures glitch-free startup in consumer AV systems. |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous ADC/DAC operation | Enables independent sampling rates (e.g., 44.1 kHz capture + 48 kHz playback) without shared clock tree - eliminates resampling artifacts and simplifies system clock architecture. |
| Dual power domains (5 V / 3.3 V) | Isolates analog signal path from digital noise sources - preserves 99 dB SNR on ADC and 105 dB on DAC despite mixed-signal integration. |
| Integrated analog filters | On-chip antialiasing (300 kHz –3 dB) and low-pass (300 kHz –3 dB) filters eliminate external passive components - reduces BOM count and PCB area in space-constrained STB designs. |
| Hardware control mode | Three-pin strap (MODE/MS/MD) configures basic functions (de-emphasis, mute, output type) - removes dependency on host processor during boot or failure recovery. |
| Zero-flag outputs (ZEROL/ZEROR) | Real-time channel activity detection - used for automatic gain control, display indicators, or power gating of downstream amplifiers when no audio is present. |
Applications
| DVD-RW Audio Processing | Digital Television Tuner Audio |
|---|---|
Use Scenario: Capturing analog audio from composite/S-video sources and converting to digital for MPEG-2 encoding or HDMI audio pass-through. IC Role / Device Role / Timing Role: Stereo ADC digitizes baseband audio; DAC reconstructs decoded digital audio for analog outputs or SPDIF generation. Use Value: 96 dB dynamic range and ±0.05 dB pass-band ripple preserve fidelity across broadcast audio bandwidth (20 Hz–20 kHz) without external calibration. | Use Scenario: Receiving digital audio streams (MPEG, AC-3) and converting to analog for RCA/SCART outputs or feeding internal speakers. IC Role / Device Role / Timing Role: DAC operates at 48 kHz or 44.1 kHz with de-emphasis enabled; ADC monitors analog tuner audio for diagnostics or secondary recording. Use Value: Hardware-mode de-emphasis (32/44.1/48 kHz) and 105 dB SNR ensure compliance with EIAJ CP-340 and ITU-R BS.468 standards. |
| Digital Set-Top Box Audio Hub | AV Receiver Preamp Stage |
Use Scenario: Aggregating audio from multiple sources (HDMI, tuner, USB) and routing to DACs or digital outputs (SPDIF, I²S). IC Role / Device Role / Timing Role: Dual asynchronous interfaces allow simultaneous 44.1 kHz tuner audio and 96 kHz HDMI audio stream handling without sample-rate conversion. Use Value: Independent BCK1/LRCK1 and BCK2/LRCK2 pins enable concurrent multi-source audio buffering - reduces latency and avoids frame-drop in real-time mixing. | Use Scenario: Converting digital audio from streaming modules (Bluetooth, Wi-Fi) into analog signals for analog preamp stages and volume control. IC Role / Device Role / Timing Role: DAC operates in master mode driving external analog switches; ADC monitors line-in for auto-input selection or level metering. Use Value: Differential 8 Vp-p output drives long cables to power amps with >100 dB common-mode rejection - eliminates hum and RF ingress in home theater environments. |
Equivalent & Alternatives

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCM3002E/200 | 16-bit resolution, 48 kHz max sampling, no DAC de-emphasis, single system clock only | Limited to CD-quality audio; lacks asynchronous operation and hardware mode flexibility | Select for cost-sensitive, fixed-sample-rate applications where 96+ dB SNR is not required. |
| AK4556VN | 24-bit, 96 kHz ADC/DAC, but synchronous-only clocking; requires external VCOM buffer | No independent ADC/DAC clocks - cannot process mismatched sample rates without external SRC | Choose when system uses single master clock and board space permits external VCOM support circuitry. |
Compared with PCM3002E/200 and AK4556VN, the PCM3060PWRG4 uniquely supports true asynchronous dual-sample-rate operation, integrated VCOM, and hardware-configurable modes - making it the only option among the three for robust, low-latency, multi-standard AV equipment without external SRC or glue logic.

FAQ
What is the maximum DAC sampling rate supported by the PCM3060PWRG4?
The PCM3060PWRG4 supports a maximum DAC sampling rate of 192 kHz, verified in the datasheet under ELECTRICAL CHARACTERISTICS (DAC section) and DEVICE DESCRIPTION. This capability enables high-resolution audio playback in Blu-ray players and studio-grade digital-to-analog conversion paths. The PCM3060PWRG4 achieves –94 dB THD+N and 105 dB SNR at 48 kHz, maintaining high fidelity across its full 16–192 kHz range.
Does the PCM3060PWRG4 support independent ADC and DAC clock domains?
Yes, the PCM3060PWRG4 supports fully independent clock domains via dedicated SCKI1 (ADC system clock) and SCKI2 (DAC system clock) inputs. This asynchronous architecture allows simultaneous operation at different sampling rates - for example, 44.1 kHz ADC capture and 48 kHz DAC playback - without requiring external sample-rate converters. The PCM3060PWRG4 datasheet confirms this in the ASYNCHRONOUS OPERATION section and Table 2.
What are the analog output configurations supported by the PCM3060PWRG4?
The PCM3060PWRG4 supports both single-ended and differential analog outputs. In single-ended mode, VOUTL+/VOUTR+ deliver 4 Vp-p; in differential mode, VOUTL+/VOUTL– and VOUTR+/VOUTR– deliver 8 Vp-p. The MODE pin strapping determines output type in hardware mode. The PCM3060PWRG4 datasheet specifies these values in the DAC CHARACTERISTICS table and PIN ASSIGNMENTS section.
Can the PCM3060PWRG4 operate without a microcontroller?
Yes, the PCM3060PWRG4 can operate in hardware mode using pin-strapped configuration (MODE, MS/ADR/IFMD, MD/SDA/DEMP). This mode enables basic functions including digital attenuation, soft mute, and de-emphasis without SPI/I²C communication. The PCM3060PWRG4 datasheet details hardware mode behavior in the MODE pin description and FEATURE section.
What is the function of the ZEROL and ZEROR pins on the PCM3060PWRG4?
ZEROL and ZEROR are open-drain zero-detection flags that assert LOW when the corresponding DAC channel output is silent (all zeros). They provide real-time activity monitoring for automatic power gating, LED indicators, or input switching - eliminating the need for host-side audio analysis. The PCM3060PWRG4 datasheet defines their timing and electrical behavior in Table 1 (TERMINAL FUNCTIONS) and the FEATURES list.
