ADS4222EVM Datasheet PDF - TI

The ADS4222EVM is an Evaluation Module for evaluate the operation and performance of ADS4222 device, an extremely low power dual channel 12-bit 65MSPS analogue-to-digital converter. The ADC features a configurable parallel DDR LVDS or CMOS outputs. The board provides a flexible environment to test the ADS4222 under a variety of clock, input and supply conditions. The board also includes new 10 output low jitter clock synchronizer and jitter cleaner device, the CDCE72010, which can be used to drive the clocking input to the ADS4222. Open sockets are provided for an external VCXO and crystal band pass filter allowing for rapid evaluation of a combined high performance ADC and clocking circuit equivalent to a final system level solution. Alternatively an external clock source can be provided to the board and either routed through the CDCE72010 or passed directly to the ADS4222 clock input.
