ADC34J22 Quad-Channel, 12-Bit, 50-MSPS Analog-to-Digital Converter Evaluation Module
This product has been released to the market and is available for purchase. For some products, newer alternatives may be available.
The ADC34J22 EVM demonstrates the performance of a low power quad 50Msps 12 bit ADC. It includes the ADC34J22 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 50 ohm single ended signal source. The clock reference input is provided via a transformer input and can be connected to a 50 ohm single ended clock source. The onboard LMK04828 can be used to generate the necessary JESD204B clocks. Register access is provided through the on board USB connection and a GUI. For a complete evaluation system, TI also offers the TSW14J50 data capture card and High Speed Data Converter Pro Software.
