Product details
Overview
PEB 4364 T V1.2 from Infineon Technologies is a dual-channel Subscriber Line Interface Circuit (SLIC) controller IC designed for voice-over-copper telephony systems, integrating SLICOFI-2 digital interface logic with programmable DC feeding, AC transmission, ringing, and supervision functions. It supports ITU-T G.712-compliant analog line interface, delivers ±72 V DC feed range, enables internal balanced ringing up to 90 VRMS, and operates in dual-channel TDM PCM mode at 2.048 MHz.
For engineers reviewing the PEB 4364 T V1.2 datasheet, PEB 4364 T V1.2 pinout, PEB 4364 T V1.2 application, or PEB 4364 T V1.2 equivalent, key selection criteria include dual-line SLIC control capability, integrated NLP and DTMF generation, caller ID buffer handling, and compatibility with SLIC-P/SLIC-E physical layer devices in VoIP gateways and ISDN terminal adapters.
Technical Context
The PEB 4364 T V1.2 implements a dual-channel digital line interface controller architecture that manages two independent SLIC channels via time-multiplexed PCM bus (2.048 MHz frame rate), supporting both single- and double-clocking modes with configurable FSC hold timing. It interfaces with external SLICs (e.g., PEB 4265/-2, PEB 4365) through dedicated control registers and status monitoring pins including HOOK, GNDK, and RSTAT.
Its functional core includes programmable DC feeding zones (constant current, resistive, constant voltage), AC transmission path with echo cancellation support, and enhanced digital signal processing features such as non-linear processor (NLP) coefficient loading, universal tone detection, and three-party conferencing logic-all coordinated via 8-bit parallel or serial SPI-like register access.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 4365 V1.2 | Integrated SLIC + controller in single chip; lacks separate SLICOFI-2 interface. | Reduced external component count but no flexibility to mix SLIC types or upgrade SLIC independently. | Select when board space is constrained and SLIC requirements are fixed. |
| PEB 4265 V1.2 | Single-channel SLIC controller; identical register map and timing but half channel capacity. | Requires two units for dual-line implementation, increasing PCB area and power consumption. | Select only for cost-sensitive single-line designs where scalability is not required. |
Compared with PEB 4365 V1.2, PEB 4364 T V1.2 offers modular SLIC pairing and superior thermal management for high-density line cards; versus PEB 4265 V1.2, it doubles channel throughput per unit area while maintaining identical firmware compatibility and diagnostic infrastructure.

FAQ
What is the maximum supported loop length for PEB 4364 T V1.2 with external SLIC-P?
The PEB 4364 T V1.2 supports loop lengths up to 18 km when paired with PEB 4265/-2 SLIC-P devices under standard 0.4 mm copper wire conditions, enabled by its ±72 V programmable DC feed range and adaptive constant-current zone configuration per ITU-T G.961 Annex A.
Does PEB 4364 T V1.2 include an integrated SLIC or require external SLIC devices?
PEB 4364 T V1.2 is a SLIC controller only and requires external SLIC devices (e.g., PEB 4265/-2, PEB 4365) for analog line driving. It provides digital control, supervision, and signal processing but does not integrate power transistors or high-voltage line drivers.
How is caller ID implemented in PEB 4364 T V1.2?
Caller ID is implemented via hardware-based Bellcore-compliant FSK modulation (1200/2200 Hz) generated internally, with dedicated buffer memory and physical layer transmission timing controlled by register bits CITACA/CITACB - no host CPU intervention required after initial setup.
Can PEB 4364 T V1.2 operate in standalone mode without a host microcontroller?
No - PEB 4364 T V1.2 requires external host initialization and register configuration via 8-bit parallel or serial interface; it has no boot ROM or autonomous startup sequence and relies on host firmware for mode selection, interrupt handling, and coefficient loading.
