About the AIF2 LLD

Purpose and Scope

This AIF2 library aims at generalizing the configuration of AIF2 for different modes (CPRI/OBSAI/ABTLib/Generic packet, WCDMA/LTE/Dual mode). The AIF2 library makes use of AIF2 Chip Support Library and CPPI/QMSS Low Level Drivers (LLDs) The AIF2 library is delivered as a RTSC package (ti.drv.aif2).

AIF2 LLD usage details are included in the user's guide

Configuration structure

AIF_ConfigObj exposes "user-friendly" parameters to allow users to configure AIF2 with a general understanding of how AIF2 HW works. Parameters such as the protocol (CPRI, OBSAI), AIF2 input clock speed, or DIO engine/PKTDMA configurations are expected from the application. AIF2 configuration examples are provided by the test examples delivered with the library.
