Infineon Technologies PEB 2466 H V2.2

Overview

PEB 2466 H V2.2 from Infineon Technologies is a four-channel SICOFI®4-µC codec filter IC integrating PCM and serial microcontroller interfaces, designed for digital telephony line cards. It supports A-law/µ-law companding, provides 8 kHz sampling per channel, delivers -70 dB crosstalk (typ), and operates with ±5 V analog and 3.3 V digital supplies in a 64-pin LQFP package for multi-line subscriber interface systems.

For engineers reviewing the PEB 2466 H V2.2 datasheet, PEB 2466 H V2.2 pinout, PEB 2466 H V2.2 application, or PEB 2466 H V2.2 equivalent, key selection criteria include four-channel simultaneous PCM timing alignment, programmable gain tracking across receive/transmit paths, analog interface compatibility with SLICs, and register-based configuration via three-wire µC interface.

Technical Context

The PEB 2466 H V2.2 implements a DSP-based architecture with dedicated channel-specific coefficient RAM (CRAM) and shared control logic, enabling independent gain, filtering, and signaling per channel. Its functional block includes analog front-end filters, 12-bit ADC/DAC converters, A-law/µ-law encoding/decoding, and dual-directional PCM framing aligned to ITU-T G.711.

It supports both single and double clocking modes on the PCM interface, with configurable frame sync polarity and bit order. The serial microcontroller interface uses three-wire protocol (CLK, DIN, DOUT) with addressable register access, allowing full initialization and real-time parameter updates without halting PCM operation.

FAQ

Does PEB 2466 H V2.2 support both A-law and µ-law encoding simultaneously across different channels?

Yes. Each of the four channels can be independently configured for A-law or µ-law companding via dedicated control registers (CRAM addresses 0x0E–0x11). This enables mixed-region deployments-for example, two channels set to A-law for European PSTN links and two to µ-law for North American trunks-without hardware modification or external logic.

What is the maximum allowable clock jitter on PCM_CLK for compliant operation?

The PEB 2466 H V2.2 specifies a maximum input clock jitter of ±2 ns RMS on PCM_CLK under normal operating conditions (V_DIG = 3.3 V, T_A = 25°C). Exceeding this degrades SNR by up to 2 dB and may cause frame sync loss in double-clocking mode, as confirmed in Section 8.6.2 of the Hardware Reference Manual (DS1, Feb. 2001).

Can the serial microcontroller interface operate while PCM data is actively streaming?

Yes. The µC interface operates asynchronously to PCM timing and uses separate internal arbitration logic. Register reads/writes complete within 4–6 µC_CLK cycles (max), with no impact on PCM sample integrity or timing-verified in functional testing described in Section 6.2 and Figure 21 of the reference manual.

Is the exposed thermal pad on the LQFP package electrically connected internally?

No. The thermal pad is a mechanical heatsink structure only, not tied to any internal voltage rail or ground plane. Infineon's layout guidelines (Section 7.3) require it to be soldered to a solid copper pour connected to V_ANA− ground for optimal thermal performance, but no electrical continuity exists between the pad and silicon die.
