CC8531: SLAC & CC85XX – to reduce the Latency / less then 5ms

Ferdinand Pohler

Part Number: CC8531

Tool/software:

Hi, I'm thinking about building a live PA setup with the CC8531. Unfortunately the latency of 11ms is not sufficient. Would it be possible for me to use SLAC as a key function to further reduce the latency?

Or simply put, how can a latency of less than 5ms be achieved?

Hello,

The best case scenario latency, as specified in datasheet, would be 10.7msec.

Other relevant posts:

It seems that for wired audio, typical latency is 5-10msec. So it's expected that adding a wireless component will introduce additional latency.
From the CC85xx User Guide,

The audio latency is defined as the delay introduced by CC85xx when replacing a wired serial audio interface (I2 S, LJF, RJF or DSP) connection between an audio producer and an audio consumer. Hence, latency values specified in the PurePath Wireless Configurator do not include delays introduced by the external audio device (e.g. a DAC) connected to CC85xx.

Thanks,
Toby
