Replace SAA7220 with SRC4192
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
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 the
- -12 dB attenuation , when Seraing
- 8 words of error interpolation
- Digital output
