Product details
Overview
PEB4365T-SV1.1 from Infineon Technologies is a dual-channel TSLIC (Telecom Subscriber Line Interface Circuit) optimized for VoIP, VoDSL, and VoCable CPE applications. It delivers 32 mA DC feed per channel, supports up to 170 V balanced ringing voltage, integrates line echo cancellation (8 ms), DTMF detection, CLIP generation, and programmable AC/DC parameters - all in a P-VQFN-48 package.
For engineers reviewing the PEB4365T-SV1.1 datasheet, PEB4365T-SV1.1 pinout, PEB4365T-SV1.1 application, or PEB4365T-SV1.1 equivalent, this device serves as a fully programmable SLIC solution requiring no external relays, ring generators, or RAM - enabling rapid deployment in lifeline-supported residential gateways and multi-line VoIP adapters.
Technical Context
The PEB4365T-SV1.1 implements a dual-channel SLIC architecture with integrated current-sense feedback and programmable longitudinal balance control. It supports both balanced and unbalanced ringing configurations and features on-chip voltage/current monitoring for remote line testing (short-circuit, capacitance, resistance).
Its serial controller interface enables full software configuration of feeding current, ring-trip threshold, loop length compensation, and AC impedance profiles - meeting global POTS requirements including ETSI, FCC Part 68, and ITU-T G.992.x without hardware changes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB4365T v1.1 | Same silicon revision but lacks "-SV" suffix - indicates standard version without enhanced screening or extended temperature grade. | Approved for commercial-grade CPE only; not qualified for industrial ambient or extended-life deployments. | Select when cost sensitivity outweighs long-term reliability requirements in consumer-grade gateways. |
| PEB4265T v1.1 | Single-channel variant in P-DSO-36 package; identical electrical specs per channel but half the integration density. | Requires two units to match dual functionality - increases PCB area, BOM count, and thermal management complexity. | Choose only if existing layout constraints prevent P-VQFN-48 adoption or require discrete channel isolation. |
Compared with PEB4365T v1.1 and PEB4265T v1.1, the PEB4365T-SV1.1 offers superior thermal performance and extended qualification for continuous operation in sealed CPE enclosures - critical for fanless residential gateways operating at 60°C ambient.

FAQ
What is the maximum loop length supported by PEB4365T-SV1.1?
The PEB4365T-SV1.1 supports up to 5 km of 0.4 mm copper loop with 32 mA DC feed and programmable loop-length compensation. Its adaptive impedance matching maintains signal integrity across varying line conditions, verified per ITU-T G.992.1 Annex A specifications.
Does PEB4365T-SV1.1 require an external crystal or clock source?
No - the PEB4365T-SV1.1 does not include an internal oscillator and relies on an external master clock from the host processor or codec (typically 2.048 MHz or 4.096 MHz). It accepts CMOS-level clock input on the CLKIN pin and synchronizes all timing functions to that reference.
Can PEB4365T-SV1.1 operate with a single 3.3 V supply?
Yes - the device operates from a single 3.3 V supply for digital and analog circuitry, generating internal negative voltages via charge-pump circuits. This eliminates need for dual-rail supplies and simplifies power design in space-constrained CPE platforms.
How is line testing performed using PEB4365T-SV1.1?
Line testing is executed via the serial controller interface using built-in diagnostic commands. The device measures line voltage, current, and injected test tones to detect shorts, opens, foreign voltage, and capacitance - returning results through MON1/MON2 analog outputs or digital status registers.
