Application Scenarios & Design Considerations

Dedicated Voice Processor with Dual Channel Codec

Alternative Part Number

  • LE88266TQC --: Microchip acquired Microsemi, which absorbed Zarlink's voice/telecom line; this is a comparable voice-processing/SLIC-family device in the same telecom interface category and is a common drop-in consideration.
  • SI32176-C-FM --: Silicon Labs ProSLIC/voice interface ICs are widely used as functional replacements for Zarlink voice-line devices, offering similar telecom line-interface functionality with broad availability.
  • PEF4268VV1.1 --: Infineon/Lantiq telecom voice interface devices serve the same application space as Zarlink voice-processing parts and are a viable second-source option for legacy designs.
