ADS4249EVM

TEXAS INSTRUMENTS  ADS4249EVM  评估模块, ADS4249EVM

The is an Evaluation Module for evaluate the operation and performance of ADS4249, an extremely low power dual channel 14-bit 250MSPS analogue to digital converter ADC. The ADC features a configurable parallel DDR LVDS or CMOS outputs. The board provides a flexible environment to test the ADS4249 under a variety of clock, input and supply conditions. The board also includes 10 output low jitter clock synchronizer and jitter cleaner device, the CDCE72010, which can be used to drive the clocking input to the ADS4249. 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 ADS4249 clock input.
