8-bit, 125MSPS ADC Evaluation board
Description
CXA1396D (8-bit, 125MSPS, high-speed A/D converter). In addition to indispensable features such as the
reference voltage generator, this tool equips two sets of analog inputs (the direct input and the buffer amplifier
input), the input voltage offset generator, the clock decimator, the output data latches, the 10-bit high-speed
DAC, and the 20-pin cable connector for digital outputs.
This evaluation board provides full performance of the CXA1396D and it is designed to facilitate evaluation.
Features
• Resolution: 8bits
• Maximum conversion rate: 125MSPS
• Supply voltage: +5.0V, –5.2V, –2.0V
• Two analog inputs (Direct input, buffer amplifier input)
• Clock level converter: Sine wave to ECL level signal
• Reference voltage adjustment circuit for the A/D converter
• Built-in clock frequency decimation circuit: (1/1 to 1/16)
