Product details
Overview
AD9204BCPZ-65 from Analog Devices is a dual-channel, 10-bit, 65 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with separate 1.8 V–3.3 V digital output drivers. It features 700 MHz analog input bandwidth, 61.3 dBFS SNR at 9.7 MHz input, and ±0.11 LSB DNL, targeting I/Q demodulation in LTE/W-CDMA receivers and ultrasound front-ends.
For engineers reviewing the AD9204BCPZ-65 datasheet, AD9204BCPZ-65 pinout, AD9204BCPZ-65 application, or AD9204BCPZ-65 equivalent, key selection considerations include its 64-lead LFCSP package, dual-channel interleaved timing with 9-cycle pipeline latency, differential clock support (CMOS/LVDS/LVPECL), and programmable data format (offset binary/gray/twos complement).
Technical Context
The AD9204BCPZ-65 employs a multistage differential pipeline architecture with output error correction logic to guarantee 10-bit accuracy and no missing codes across −40°C to +85°C. Its patented sample-and-hold circuit maintains performance up to 200 MHz input frequency while enabling low-power operation.
Dual independent ADC cores share a common analog supply (AVDD) and reference but feature separate digital outputs (D0A–D9A, D0B–D9B), dedicated data clocks (DCOA/DCOB), and out-of-range flags (ORA/ORB). Serial port interface (SPI) configures clock division (1-to-8), duty cycle stabilization, test pattern generation, and power-down modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - guarantees monotonic transfer function and no missing codes over full industrial temperature range. |
| Sample Rate | 65 MSPS - fixed maximum conversion rate for this variant; supports real-time digitization of IF signals up to 200 MHz via undersampling. |
| SNR @ 9.7 MHz | 61.3 dBFS - defines dynamic range usable in GSM/EDGE baseband receivers with >9.8 ENOB. |
| SFDR @ 9.7 MHz | 75 dBc - enables detection of weak signals adjacent to strong interferers in diversity radio systems. |
| Analog Input BW | 700 MHz - allows direct RF sampling of L-band signals without external amplification or filtering. |

| Power @ 65 MSPS | 61.1 mA AVDD + 6.5 mA DRVDD (1.8 V) = 121.7 mW - enables battery-powered handheld scope meters with thermal management via exposed paddle. |
Pinout & Package
AD9204BCPZ-65 is housed in a 64-lead, 9 mm × 9 mm, RoHS-compliant LFCSP package with an exposed thermal paddle that must be soldered to AGND for electrical noise control, mechanical stability, and thermal dissipation (θJA = 23°C/W, still air).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (exposed paddle) | Primary ground reference | Only ground connection for chip; mandatory soldering to PCB AGND plane for signal integrity and thermal reliability. |
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; internal bias sets common-mode at 0.9 V; enables jitter-insensitive sampling with optional duty cycle stabilizer. |
| VIN+A, VIN−A / VIN+B, VIN−B | Differential analog inputs | High-Z, 6 pF input capacitance; 700 MHz bandwidth; common-mode range 0.5 V–1.3 V; optimized for transformer-coupled IF signals. |
| D0A–D9A, D0B–D9B | CMOS digital outputs | 10-bit parallel outputs per channel; MSB-aligned (D9A/D9B); support 1.8 V/3.3 V logic; multiplexable onto shared bus via OEB control. |
| DCOA, DCOB | Data clock outputs | Source-synchronous clocks aligned to respective channel data; programmable phase offset ensures setup/hold compliance with FPGA/ASIC receivers. |
| PDWN, OEB, CSB, SCLK/DFS, SDIO/DCS | Control interface | 30 kΩ internal pull-up/down resistors enable SPI configuration or static mode selection without external biasing components. |
Key Features
| Feature | Design Value |
|---|---|
| Scalable analog input range | 1 Vp-p to 2 Vp-p differential - simplifies gain staging across multimode receivers (GSM to LTE) without redesigning front-end filters. |
| Programmable clock divider | Integer 1-to-8 division - decouples system clock domain from ADC sampling rate, easing synchronization in smart antenna arrays. |
| Built-in test pattern generation | Deterministic, pseudorandom, and user-defined patterns via SPI - eliminates need for external signal generators during production test of PET/SPECT imaging modules. |
| Energy-saving power modes | 2.2 mW power-down, 37 mW standby - extends battery life in handheld scope meters during idle intervals without losing configuration state. |
| On-chip voltage reference | 1.0 V ±12 mV (0.981–1.005 V) - removes external reference IC, reducing BOM count and layout area in space-constrained ultrasound probes. |

FAQ
What is the maximum analog input frequency supported by AD9204BCPZ-65?
The AD9204BCPZ-65 supports analog input frequencies up to 200 MHz while maintaining specified AC performance (61.0 dBFS SNR, 73 dBc SFDR). Its 700 MHz small-signal analog input bandwidth enables undersampling architectures for direct RF digitization in L-band radar and wireless infrastructure applications.
Does AD9204BCPZ-65 require an external voltage reference?
No, AD9204BCPZ-65 integrates a precision 1.0 V on-chip voltage reference with ±12 mV tolerance over temperature. External reference is optional via the VREF pin, but the internal reference eliminates BOM cost and layout area in most applications including handheld scope meters and ultrasound probes.
How is channel synchronization achieved in AD9204BCPZ-65?
AD9204BCPZ-65 uses a shared differential clock (CLK+/CLK−) and dedicated SYNC input to align the internal clock dividers of both ADC channels. This ensures deterministic, sub-nanosecond inter-channel timing skew critical for I/Q demodulation and beamforming in smart antenna systems.
What digital output formats does AD9204BCPZ-65 support?
AD9204BCPZ-65 supports three programmable data formats via SPI or static pin control: offset binary (default), gray code, and twos complement. Format selection is implemented through the SCLK/DFS pin or register 0x08, enabling compatibility with diverse FPGA logic families and DSP algorithms.
Is AD9204BCPZ-65 pin-compatible with other Analog Devices ADCs?
Yes, AD9204BCPZ-65 uses a 64-lead LFCSP package identical to the AD9268 (16-bit), AD9251/AD9258 (14-bit), and AD9231 (12-bit) families. This enables hardware reuse and migration paths between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS without PCB redesign.
