AK4132
96kHz 24bit Sample Rate Converter
1. General Description
The AK4132 is an 2ch digital sample rate converter (SRC). It converts sample rate of the input audio
source (from 8kHz to 96kHz) to 44.1kHz or 48kHz. It is possible also to convert 8kHz, 16kHz or 24kHz
into 8kHz, 16kHz or 24kHz. The AK4132 has an internal oscillator and does not need any external
master clocks. It contributes simplifying a system configuration. The AK4132 is suitable for the
application interfacing to different sample rates such as Car Audio Systems and DVD recorders.
