Replace SAA7220 with an SRC4192

Update 06-04-2026 , Lets finish this project 😉 , made Proto 2 

The board board will upsample the 44.1kHz to 192 kHz , by removing the SAA7220 We will lose te following features is the cd-player.

  • -12 dB attenuation , when Searching
  • 8 words of error interpolation
  • Digital output

 

Building in progress

 

 

Video :  SRC4192 First Test

 

The Idea started in 2021

Can we use a SRC4192 instead off a SAA7220 in a Philips chipset CD player , proof of concept

Quick test new Clock with PLL 1707

 

 

 

Max Bit clock TDA1541 6.4 MHz..

 

 

Proof of Concept , testing Slave – Slave mode

Succes input spdif at 192 kHz freq.  a  50 kHz Tone

Digital generated squarewave 1 kHz at 192 kHz sample rate

Digital generated squarewave 1 kHz at 44.1 kHz
