RXADC_14 Pmod

This is an ADC designed for use in digitizing RF signals with up to 40MHz bandwidth and 80dB SNR. The form-factor is compatible with a dual-connector Digilent Pmod so that it can be used with commonly available FPGA development boards to build a variety Software-Defined radio functions.

Features:

  • ADC14C105 14-bit 105MSPS RXADC.
  • Onboard 3.3V Regulator (5V input)
  • Filtered Analog 3.3V Supply
  • Onboard 80MHz clock oscillator
  • Digilent-compatible 2-connector Pmod interface
  • 50-ohm SMA input – 2.5Vpp ~= 0dBfs
