The AK4128AEQ from Asahi Kasei Microdevices (AKM) is an 8-channel asynchronous sample rate converter (SRC) designed for digital audio interfacing. It supports input sample rates from 8kHz to 216kHz and output sample rates from 8kHz to 216kHz, with an input-to-output ratio of 1/6 to 6. The device integrates an internal oscillator, eliminating the need for external master clocks and simplifying system design.
Key performance specifications include a typical THD+N of -130dB and a dynamic range of 140dB (A-weighted). The AK4128AEQ supports multiple digital audio interface formats: I²S, TDM, MSB justified, and LSB justified. It also features a digital de-emphasis filter for 32kHz, 44.1kHz, and 48kHz sample rates, a soft mute function, and an SRC bypass mode. The μP interface is I²C.
This SRC is ideal for multi-channel audio applications such as car audio systems, DVD recorders, and other digital audio interfacing systems. The device is supplied in a 64-LQFP (10x10) package with surface mount gull-wing leads. It operates from a 3V to 3.6V supply voltage and over a temperature range of -20°C to 85°C.
