Product details
Overview
TP13054BDWR from Texas Instruments is a monolithic PCM codec and filter IC designed for full-duplex voice telephony interface in TDM systems. It integrates µ-law A/D and D/A conversion, transmit high-pass/low-pass filtering, receive low-pass filtering with (sin x)/x correction, active RC noise filters, and internal precision voltage reference. Operates at ±5 V, delivers 50 mW typical active power, supports –40°C to 85°C industrial temperature range, and targets line interface cards in T1/PABX/central office systems.
For engineers reviewing the TP13054BDWR datasheet, TP13054BDWR pinout, TP13054BDWR application, or TP13054BDWR equivalent, key selection criteria include µ-law PCM compatibility, dual master clock support (1.536/1.544/2.048 MHz), short- or long-frame sync flexibility, transmit idle noise performance (≤9 dBrnC₀), and industrial-grade thermal specification.
Technical Context
The TP13054BDWR implements a complete analog-to-digital and digital-to-analog signal chain for voice-band PCM systems, with integrated switched-capacitor band-pass and low-pass filters on transmit and receive paths. Its architecture includes autozero circuitry for offset stability, TTL/CMOS-compatible serial I/O, and independent transmit/receive frame-sync and bit-clock domains.
It supports both synchronous (MCLKX only, MCLKR/PDN as power-down control) and asynchronous (separate MCLKX/MCLKR) operation modes, with automatic 193rd-pulse compensation for 1.544 MHz T1 framing. The device uses internal voltage reference and precision analog front-end to achieve ±0.15 dB absolute gain flatness from 300 Hz to 3000 Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Codec Law | µ-law compliant - ensures interoperability with North American and Japanese digital telephony infrastructure |
| Operating Temperature | –40°C to +85°C - qualified for industrial line-card and outdoor telecom equipment deployment |
| Supply Voltage | ±5 V (±5%) - requires dual-rail analog supply; VCC = +5 V, VBB = –5 V |
| Active Power Dissipation | 9 mA typical ICC + IBB - ~50 mW total, enabling high-density line interface card designs |
| Transmit Noise (C-weighted) | 9 dBrnC₀ typical - meets stringent voice channel idle noise requirements per Telcordia GR-909 |
| Receive Filter Gain Flatness | ±0.15 dB (300–3000 Hz) - preserves speech intelligibility and tone fidelity across voiceband |
| Envelope Delay Variation | ±40 µs max relative delay (1000–1600 Hz) - minimizes phase distortion in echo-cancellation-sensitive systems |
Pinout & Package
TP13054BDWR is housed in a 16-pin SOIC (DW) package with 1.27 mm pitch, optimized for surface-mount assembly on telecom line cards. Pin functions are electrically and thermally isolated per TI SCTS042A Rev. July 1996.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB (Pin 1) | Negative analog supply | –5 V rail; must be stable and low-noise; connects to analog ground via local decoupling |
| ANLG GND (Pin 2) | Analog reference ground | Separate from digital ground; all analog signals referenced here to minimize noise coupling |
| VFRO (Pin 3) | Receive filter analog output | Low-impedance buffered output (1–3 Ω); drives 600 Ω loads or op-amp inputs directly |
| VCC (Pin 4) | Positive analog supply | +5 V rail; supplies analog core, DAC, and filters; requires 0.1 µF ceramic bypass |
| FSR (Pin 5) | Receive frame-sync input | 8 kHz pulse train; triggers latching of PCM data into DR on falling edge of BCLKR |
| DR (Pin 6) | Receive serial data input | PCM data stream input; sampled on falling edge of BCLKR after FSR leading edge |
| BCLKR/CLKSEL (Pin 7) | Bit clock input / clock select | In sync mode: logic input selecting 1.536/1.544 MHz vs. 2.048 MHz master clock |
| MCLKR/PDN (Pin 8) | Receive master clock / power-down | Low = active; high = power-down (3 mW standby); also accepts 1.536/1.544/2.048 MHz clock |
| MCLKX (Pin 9) | Transmit master clock | Primary timing source for encode path; must be 1.536/1.544/2.048 MHz; asynchronous to MCLKR allowed |
| BCLKX (Pin 10) | Transmit bit clock | Shifts PCM data out on DX; 64 kHz–2.048 MHz, synchronous to MCLKX in sync mode |
| DX (Pin 11) | Transmit serial data output | 3-state PCM output; enabled by FSX; outputs sign-bit first on rising edge of BCLKX |
| FSX (Pin 12) | Transmit frame-sync input | 8 kHz pulse train; initiates encoding cycle; enables DX output buffer on rising edge |
| TSX (Pin 13) | Transmit slot indicator | Open-drain pulse low during encoder time slot; used for external timing synchronization |
| GSX (Pin 14) | Transmit amplifier gain sense | Analog output of transmit input amplifier; used with external resistor network to set gain |
| VFXI+ (Pin 16) | Transmit non-inverting input | High-impedance (+10 MΩ) differential input for voice signal; ±2.5 V common-mode range |
| VFXI– (Pin 15) | Transmit inverting input | Differential complement to VFXI+; enables balanced input configuration and common-mode rejection |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCM codec and filter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TP3054BDWR | Commercial temperature range (0°C to 70°C); identical pinout, µ-law, and electrical specs except temp grade | Restricted to climate-controlled central office or lab environments; not suitable for outdoor or industrial enclosures | Select TP3054BDWR only when ambient operating temperature remains within 0–70°C and cost sensitivity outweighs field-reliability requirements. |
| TP13057BDWR | A-law compliant instead of µ-law; otherwise identical industrial temp rating, package, and timing architecture | Required for E1-based systems (Europe, Asia) and ITU-T G.711 A-law infrastructure; incompatible with µ-law PCM streams | Choose TP13057BDWR exclusively for A-law deployments - no software or hardware adaptation compensates for law mismatch. |
Compared with TP3054BDWR, TP13054BDWR provides extended thermal resilience for field-deployed telecom gear, while TP13057BDWR shifts compliance to A-law ecosystems - neither offers µ-law functionality at industrial temperature without the TP13054BDWR's specific combination of law, grade, and pinout.

FAQ
What is the operating temperature range of the TP13054BDWR?
The TP13054BDWR is specified for operation from –40°C to +85°C. This industrial temperature grade enables reliable deployment in uncontrolled environments such as roadside cabinets, remote DSLAMs, and outdoor wireless base stations - unlike the commercial-grade TP3054BDWR (0°C to 70°C). All electrical parameters in the TI SCTS042A datasheet are guaranteed across this full range.
Does the TP13054BDWR support both short-frame and long-frame sync modes?
Yes, the TP13054BDWR supports both short-frame and long-frame synchronization. On power-up, it defaults to short-frame mode (1-bit-wide FSX/FSR pulses), but automatically detects long-frame pulses (≥3 bit clocks) and adapts timing accordingly. This dual-mode capability ensures interoperability with legacy T1 systems and modern hybrid TDM architectures without hardware modification.
What is the significance of the "DWR" suffix in TP13054BDWR?
The "DWR" suffix denotes a 16-pin SOIC package (DW) with tape-and-reel packaging (R) - standard for automated SMT assembly. The DW package has 1.27 mm lead pitch and meets JEDEC MS-012 specifications. This is the only package variant documented for TP13054B in TI's SCTS042A datasheet; no ceramic or chip-scale variants exist for this part number.
Can the TP13054BDWR be used in A-law PCM systems?
No, the TP13054BDWR is µ-law only. For A-law applications, TI specifies the TP13057BDWR - an identical industrial-grade device with A-law encoding/decoding. Attempting to use TP13054BDWR in an A-law system results in severe quantization distortion and failed interoperation with ITU-T G.711 A-law infrastructure. The law type is hardwired and not user-configurable.
How does the TP13054BDWR achieve low transmit idle noise?
The TP13054BDWR incorporates patented circuitry that actively suppresses idle-channel noise to ≤9 dBrnC₀, meeting Telcordia GR-909 Class A requirements. This is achieved through optimized autozero calibration, precision internal voltage reference, and dedicated active RC noise filters - not merely through external component selection. However, TI cautions against use when composite transmit signals fall below –55 dBm0.
