The OSVA project is a 2 channels signal analyzer using high resolution SAR ADC (LTC2380-24). It has been designed to be used as system analyser but using standard digital audio interface.
- AA2380 - 2 channels ADC board : It is the main board.
- AA10M08 - CPLD digital board : Optional board
- AAPSU01 - Low noise SMSP board
- AACMD01 - Command panel board
- 2 ADC Channels using LTC2380-24 (or compatible device)
- 24 bits resolution up to 1536 ksps
- 10Vpp full-scale signal sensitivity (default)
- Single-ended or fully differential mode (switchable)
- 2 analog anti-alias filter cuttoff (38.4kHz/384kHz by default)
- On board ultra low jitter clock
- Direct SPDIF stereo output with support up to 192kHz sampling.
- SinC type Digital filter (x1 to x32 selectable).
- isolated 100MHz External clock input (for sampling synchronisation)
- 2 isolated analog output for coherant sampling capability.
- isolated High speed digital interface to connect :
- AA10M08 dedicated Digital board
- USB-Streamer from mini-DSP for 4 channels 24/192k to USB
- SDR-Widget board for 24/192k I2S to USB
