Product details
Overview
PSB 2134 H V2.2 from Siemens AG is a four-channel programmable codec-filter IC for terminal applications, implementing SICOFI®4-TE architecture with integrated A/µ-law PCM conversion, digital filters, dual tone generators per channel, and IOM-2 interface compatibility (1.536 MHz DCL, 768 kHz bit clock). It supports POTS line interfaces with programmable transhybrid balancing, AC impedance matching, and ring frequency generation (50 Hz or 20 Hz via RGEN pin), used in multi-line ISDN terminal adapters and country-specific telephony equipment.
For engineers reviewing the PSB 2134 H V2.2 datasheet, PSB 2134 H V2.2 pinout, PSB 2134 H V2.2 application, or PSB 2134 H V2.2 equivalent, key selection considerations include IOM-2 timing compliance, dual-tone generator configuration, programmable filter coefficient loading via serial µC interface, and SLIC control I/O capability across four channels.
Technical Context
The PSB 2134 H V2.2 implements a DSP-based architecture with fully programmable digital filters for transmit/receive paths, enabling software-defined adaptation to regional POTS requirements including transhybrid loss (>35 dB), frequency response (300–3400 Hz ±0.5 dB), and gain tracking (±0.1 dB). Its internal bandgap reference ensures ±0.5% analog level accuracy without external calibration.
It integrates four independent signaling I/O ports (SIx/SBx/SOx), interrupt generation on off-hook detection (INT12/INT34), and direct transformer drive capability (300 Ω load, ±2.5 V swing). The RGEN pin delivers programmable ring frequency (50 Hz EU or 20 Hz US) using one external divider, eliminating discrete oscillator circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-channel telecom codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Siemens PSB 2132 H | Two-channel version; identical register map, pinout subset, and firmware compatibility | Limited to dual-line terminals; lacks CH3/CH4 signaling I/O and associated interrupt pins | Select when system requires only two POTS lines and board space or cost optimization is critical |
| Infineon TLE6240-2G | Non-programmable analog front-end; no integrated codec, filters, or tone generation | Requires external DSP or MCU for signal processing; supports only basic SLIC control | Choose only if existing design uses discrete DSP and demands higher analog current drive (±100 mA vs. PSB2134's ±25 mA) |
Compared with PSB 2132 H, the PSB 2134 H V2.2 adds two full POTS channels with identical feature depth, while the TLE6240-2G shifts signal processing burden to external silicon-making PSB 2134 optimal for integrated, firmware-adaptable terminal designs.

FAQ
What is the maximum supported PCM timeslot count per channel?
The PSB 2134 H V2.2 supports up to 32 timeslots per channel via IOM-2 interface, with programmable assignment of receive/transmit slots on DU and DD lines. Each channel can be independently mapped to any slot within the 1.536 MHz frame, enabling flexible voice/data multiplexing without external time-slot interchange hardware.
Does PSB 2134 H V2.2 require external anti-aliasing or reconstruction filters?
No external analog filters are required. All filtering-including anti-aliasing, reconstruction, transhybrid cancellation, and frequency response shaping-is performed digitally using programmable FIR filters. Only two external coupling capacitors per channel (as specified in DS 1 Section 9.1) are needed for DC blocking at the analog interface.
How is ring frequency configured for different regional standards?
Ring frequency is set via register XR6 bits [7:4], selecting either 50 Hz (EU/ETSI) or 20 Hz (US/ANSI) base output on the RGEN pin. An external binary counter (e.g., 74HC393) divides this output to achieve exact line frequency; no crystal or PLL is required, simplifying compliance across global deployments.
Can PSB 2134 H V2.2 operate in standalone mode without a microcontroller?
No. The device requires continuous initialization and runtime control via its serial µC interface (DIN/DOUT/DCLK/CS). All functional blocks-including codec enable, filter coefficients, tone parameters, and signaling I/O states-are loaded and updated through this interface; no internal non-volatile memory or default boot configuration exists.
