Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SLIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB3264-2F v1.4 | No internal ring support; requires external ring generator | Suitable only where external ringing circuitry already exists | Select when board space allows external HV components and cost sensitivity outweighs integration benefit |
| PEB4264T v1.1 | Single-channel, P-DSO-20 package; lower max ringing voltage (85 Vrms) | Requires two units for dual-line systems; limited to shorter loops | Choose for low-density designs or legacy upgrades where footprint constraints prevent P-DSO-36 use |
Compared with PEB3264-2F v1.4 and PEB4264T v1.1, the PEB3264HV1.4P uniquely combines dual-channel integration, 170 V ringing, and full line diagnostics in one P-DSO-36 package - enabling higher reliability, smaller footprint, and reduced field service costs in carrier-grade CPE.

FAQ
What is the maximum loop length supported by PEB3264HV1.4P?
The PEB3264HV1.4P supports up to 5 km of 0.5 mm copper loop with 32 mA DC feed current and 170 V ringing voltage, meeting ITU-T G.992.1 and GR-909 requirements. Loop length depends on wire gauge and loading; actual reach is verified using its integrated line testing features.
Does PEB3264HV1.4P require external components for DTMF generation?
No. The device integrates a full DTMF receiver and transmitter, including tone generation and detection circuitry. No external filters, op-amps, or tone ICs are needed - all DTMF functionality is configured via its serial control interface.
How does lifeline mode operate in PEB3264HV1.4P?
Lifeline mode reduces power consumption while maintaining one active POTS line with minimum 20 mA feed current and basic ringing capability. It is triggered automatically during brownout conditions or manually via serial command, ensuring emergency calling remains functional under grid stress.
Can PEB3264HV1.4P be used in ISDN applications?
Yes - it supports ISDN NT1+ terminal equipment by providing analog POTS extension with CLIP generation, metering pulses (TTX), and programmable impedances compliant with ETSI TS 101 515. It interfaces directly with S/T-bus controllers and does not replace the ISDN protocol stack.
