The DAC3 Project (1995)
I wanted to be able to compare different DAC chips under the same conditions. Therefore the next DAC I was going to build had to have a modular approach. Special attention throughout the design was paid to jitter reduction. I included a secondary VCXO driven PLL after the one build into the CS8412 and also designed completely independent power supplies for the different areas of the circuit.
Features:
- Crystal® CS8412 digital input receiver
- Jitter attenuator using a VCXO driven PLL
- Burr Brown® DF1700 digital filter
- Plug-in digital/analog converter modules (4 different modules):
Burr Brown® PCM63 (preferred by sound quality)
Burr Brown® PCM1702
Crystal® CS4303
Crystal® CS4328 - 2nd order filtering using a two stage complementary JFET design
- Push-pull voltage regulators
