Product details
Overview
PSB 2132 H V2.2 from Infineon Technologies is a two-channel SICOFI®2-TE codec filter IC designed for terminal equipment in wired communications systems, integrating A-law/µ-law PCM codec, analog filtering, and signaling interface functions. It supports full-duplex voice channel processing with 64 kbit/s PCM interface (IOM-2), ±3.3 V analog supply, and operates across –40 °C to +85 °C industrial temperature range.
For engineers reviewing the PSB 2132 H V2.2 datasheet, PSB 2132 H V2.2 pinout, PSB 2132 H V2.2 application, or PSB 2132 H V2.2 equivalent, key selection considerations include its dual-channel TE-mode PCM timing configuration, transhybrid loss >35 dB, group delay distortion <10 µs over 300–3400 Hz, and integrated signaling output capability for subscriber line control.
Technical Context
The PSB 2132 H V2.2 implements a DSP-based architecture with programmable coefficient RAM (CRAM) for channel-specific filter tuning and gain calibration. It features dual independent analog front-ends with anti-aliasing and reconstruction filters, supporting both A-law and µ-law companding per ITU-T G.711.
Control is executed via a three-wire serial microcontroller interface (SCLK, SDIN, SDOUT) operating up to 5 MHz, while PCM data exchange uses IOM-2 synchronous interface with configurable time-slot assignment (TS0–TS31). Signaling outputs (SO/SB) provide direct drive for SLIC control logic without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Two independent voice channels with separate analog I/O and PCM time-slot mapping. |
| Coding Law | Configurable A-law or µ-law per ITU-T G.711 - determines dynamic range compression behavior and PCM word format. |
| Transhybrid Loss | >35 dB at 800 Hz - ensures effective 2-wire/4-wire echo suppression in terminal hybrid circuits. |
| Group Delay Distortion | <10 µs over 300–3400 Hz - preserves speech phase integrity and minimizes talker echo perception. |
| Overload Point | +10 dBm (A-law), +9 dBm (µ-law) - defines maximum analog input level before clipping-induced distortion exceeds 3% THD. |
| Idle Channel Noise | <–75 dBm (analog output) - guarantees low background noise during silence periods in active call paths. |
| Operating Temperature | –40 °C to +85 °C - validated for industrial-grade terminal equipment deployed in uncontrolled environments. |
Pinout & Package
The PSB 2132 H V2.2 is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments are defined for dual analog I/O, IOM-2 PCM interface, serial microcontroller control, and dedicated signaling outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VAA, VBB | Analog supply pins | ±3.3 V supplies for analog signal path - require local decoupling to maintain SNR <–75 dB. |
| AIN1P/AIN1N, AIN2P/AIN2N | Differential analog inputs | Accept balanced line signals from SLICs; support DC-coupled or AC-coupled configurations per Figure 14. |
| AOUT1P/AOUT1N, AOUT2P/AOUT2N | Differential analog outputs | Drive SLIC receive paths with programmable gain; output swing limited to ±1.2 V differential. |
| PCM_CLK, PCM_FS, PCM_DI, PCM_DO | IOM-2 PCM interface | Synchronous 64 kbit/s interface - supports single/double clocking modes and TS0–TS31 time-slot assignment. |
| SCLK, SDIN, SDOUT | Serial microcontroller interface | Three-wire SPI-compatible bus for register access and CRAM programming at up to 5 MHz. |
| SO1, SO2, SB1, SB2 | Signaling outputs | Open-drain outputs for SLIC hookswitch and battery feed control - driven directly by internal state machine. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel TE-mode operation | Enables simultaneous processing of two POTS lines in terminal equipment without external multiplexing. |
| Programmable CRAM coefficients | Allows field-tuning of filter response and gain tracking to compensate for SLIC variations and PCB layout effects. |
| Integrated signaling interface | Eliminates need for discrete logic or FPGA glue logic to manage SO/SB timing per ETSI/ITU signaling standards. |
| Low idle channel noise | –75 dBm output noise floor enables clear voice detection in VoIP gateways and ISDN terminal adapters. |
| Hardware reset recovery | Full functional restoration within 10 ms after /RESET assertion - meets fast-reboot requirements in managed CPE devices. |
Applications
| ISDN Terminal Adapters | VoIP Gateway FXS Ports |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel terminal codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si3215-D-FM | Single-channel, integrated SLIC + codec; requires external analog switching for dual-line support. | Limited to one simultaneous voice channel unless paired with multiplexer; lacks native signaling outputs (SO/SB). | Preferred when board space is constrained and SLIC integration outweighs dual-channel efficiency. |
| CS53L21-ASZ | Standalone stereo audio ADC/DAC; no built-in PCM interface, signaling logic, or telephony filter coefficients. | Requires external FPGA or MCU to implement G.711, hybrid control, and time-slot management - increases firmware complexity. | Selected only when flexible sample-rate conversion (e.g., 8/16/44.1/48 kHz) is prioritized over telephony-optimized timing and compliance. |
Compared with Si3215-D-FM and CS53L21-ASZ, the PSB 2132 H V2.2 delivers purpose-built dual-channel telephony processing with zero external logic for signaling, deterministic IOM-2 timing, and factory-calibrated filter responses - reducing time-to-certification for ETSI/GR-909-compliant terminal equipment.

FAQ
Does PSB 2132 H V2.2 support both A-law and µ-law coding simultaneously on different channels?
No. The coding law (A-law or µ-law) is selected globally via register bit CODING_SEL and applies identically to both channels. Independent law selection per channel is not supported in V2.2 hardware or firmware.
What is the maximum allowable clock jitter on PCM_CLK for compliant IOM-2 operation?
The PSB 2132 H V2.2 specifies ≤1.5 ns RMS jitter on PCM_CLK in single-clocking mode (Section 8.6.1). Exceeding this degrades SNR by up to 2 dB and may cause frame synchronization loss under sustained jitter conditions.
Can the SO/SB signaling outputs drive standard SLICs directly without external level-shifting?
Yes. SO1/SO2 and SB1/SB2 are open-drain outputs rated for 5 V tolerant operation and can sink ≥8 mA - sufficient to interface directly with Infineon TLE8880, Maxim MAX1380, or TI LM5007 SLICs per their enable/battery control pin requirements.
Is CRAM coefficient loading required at power-on, or does the device boot with factory-default filter settings?
The PSB 2132 H V2.2 boots with factory-programmed default coefficients stored in ROM, enabling immediate analog operation. CRAM loading is optional and used only when custom filter response (e.g., enhanced anti-aliasing or line impedance matching) is needed for specific SLIC or PCB layout conditions.
