universial analog to digital / digital to analog converter board

Gerber file of first board prototype

The first prototype of my new AD/DA converter board with ASRC is finished and in production since yesterday.

I will expect it within the next three weeks. 

Key Features are:

• Up to 14 audio in- and outputs!
• High Quality powersupply design for analog and digital power. Digital power has a wide voltage input range, selectable via jumpers.
• 4 Channel high quality analog audio inputs and outputs with BurrBrown buffers and special audiograde "FineGold" caps.
• Upgradeable to 6 analog audio inputs and 8 analog audio outputs.
• 8 Channel digital audio input. Selectable as Master or Slave. Any digital input is routeable to a ASRC via I2C commands. In this case you are able to input any I2S audio source you want.
• Fully buffered clocksignal outputs. Every output has a own bufferstage!
• Cost efficient 2-layer pcb design with a nearly unbroken ground plane.
