Description

  • Polymorph usb soundcard (USB <--> [I2S/DSP/LJF/RJF]) based on "SDR Widget" project
  • On board is already codec which can sniff I2S/DSP/RJF/LJF bus (RX or TX data)
  • For normal operation no extra drivers needed. Using standard drivers included in nearly all operating systems
  • Development is also possible at Windows and Linux
  • Updating FW is possible directly through USB interface (drivers are part of programmer SW). No external tool needed.

Parameters

  • CPU: AVR32 UC3A3256
  • As clock source generator is used CS2200
  • On board is DAC TLV320AIC33
  • Supported sampling frequencies: 8000, 11025, 16000, 22050, 24000, 32000, 44100 and 48000 Hz
  • Supported digital audio interfaces: I2S, DSP, Left justified, Right justified
  • Bit precision: up to 24 bit
  • Control thru USB HID (HW bridge uniprot)
  • Device is highly configurable (master/slave, BCLK oversampling, MCLK oversampling, MCLK offset, word offset, word precision...)
  • Debug messages can be sent through UART interface (115200-8-N-1). This pin is wired out to 2.54 pin header -> easy to connect
