• Small Private Branch Exchange (PBX) systems
• 4-port SDSL line cards

Telecom Procurement Notes

Verify the specific suffix 'F' against official Infineon documentation to confirm package type and temperature range. Confirm Version 3.1 revision status as this component dates from 2003. Request current availability and lifecycle status directly from authorized distributors or Infineon sales offices due to potential end-of-life conditions.

Telecom Selection Notes

Select the PEB 20571 over the PEB 20570 when port-based functionality and DMA support are required. Ensure the host system can provide the necessary clock frequencies and supports the selected microprocessor interface mode (Intel/Infineon or Motorola). Verify that the application requires the specific protocol stack capabilities integrated into the DELIC-PB architecture.

Telecom Part Context

This component belongs to the DELIC family of wired communications controllers. It serves as a bridge between digital signal processing algorithms and physical layer interfaces in telecommunications infrastructure. The V3.1 designation indicates a specific hardware revision within the product lineage, often involving minor electrical or pinout adjustments compared to earlier versions.
