CS8421 Module

Asynchronous Sample Rate Converter/Upsampling Module CS8421 32Bit/192kHz

Low jitter I2S output (using the clock output of the CD-Pro) via CS-8421 Cirrus chip.

Optional fixed upsampling can be set.

Own low noise power supply.

Output can be used as I2S or s/dif AES/EBU.

Technical data:

  • Input: I2S
  • Output: I2S
  • Max sampling rate 192kHz
  • 26 x 32 mm

The onboard clock is not used with this module! Instead, an external clock 16.9344 Mhz or the clock output of the CD module can be used.

The CD module is supplied with a low jitter clock. The already clean clock is passed on to the CS8421.

This module reduces the jitter of the I2S output.

The I2S signal can directly feed a DAC or it is converted to s/dif or AES/EBU by another module.
