Texas Instruments ADC34J2xEVM Evaluation Modules (EVMs)

Texas Instruments ADC34J2xEVM Evaluation Modules (EVMs) demonstrate the performance of a low power quad 50Msps to 160Msps 12-bit ADCs. It includes the ADC34J2x device, LMK04828 JESD204B clocking solution and TI voltage regulators to provide the necessary voltages. The input for the ADC is connected to a transformer input which can be connected to a 50ohm single ended signal source. The clock reference input is provided via a transformer input and can be connected to a 50ohm single ended clock source. The on-board LMK04828 can be used to generate the necessary JESD204B clocks. Register access is provided through the on board USB connection and a GUI.

Features

  • Single 1.8V supply to simplify power requirements
  • Flexible input clock buffer with 1/2/4 divider to simplify clocking
  • JESD204B data interface to simplify the digital interface, compliant up to 3.2Gbps lane rates
  • On-chip dither to improve SFDR
  • Supports subclasses 0,1,2 for synchronization and compatibility
  • Pin compatibility with 12/14 bit and dual/quad devices
