The ADS62C17EVM is a circuit board that allows designers to evaluate the performance of Texas Instruments' ADS62C17 device, a dual channel 11-bit 200 MSPS analog to digital converter featuring TI's SNRBoost technology. The ADC features a user selectable parallel CMOS or DDR LVDS output. Users can use either the TSW1100 (CMOS mode) or TSW1200EVM (DDR LVDS mode) to capture the data from the converter. The EVM provides a flexible environment to test the ADS62C17 under a variety of clock, input and supply conditions.
The ADS62C17EVM also includes an open socket for Texas Instrument’s new 10 Output Low Jitter Clock Synchronizer and Jitter Cleaner device, the CDCE72010, which can be used to drive the clocking input to the ADS62C17. Open sockets are also 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 EVM and either routed through the CDCE72010 or passed directly to the ADS62C17 clock input. By default, the EVM is designed for an external clock source to directly clock the ADS62C17.
The evaluation module also allows designers to use either a transformer coupled input into the ADC or an amplifier input based on the Texas Instruments' THS4509. While the ADC EVM comes with the THS4509, users can easily evaluate any of the footprint compatible ADC driving amplifiers such as the THS4508, THS4511 and THS4520.
