TLV3801EVM: LVDS output capture

Paolo Carbone

Part Number: TLV3801EVM

Hi,

I'm looking for a board to capture the one-bit data stream output by this comparator to store data for offline processing.  

The comparator would act as a one-bit ADC. 

Acquisition at 1 Gs/s sampling rate would be enough. I was looking at the TWS1400EVM. Is this a viable choice, even though it is discontinued?

Thank you for your support.

Paolo

    Paolo,

    The TSW1400 normally uses an input clock with the input data. Not sure on how you plan on capturing this 1-bit data. There is a chance of getting this to work with existing firmware and software but a clock would be required, and the data would have to meet setup and hold time requirements with respect to the clock. With one of the existing modes, the clock is 1/2 the data rate and data is captured on every edge of the clock. This mode operates up to 1GSPS for the data. This uses a 12-bit ADC device. You would have to discard the upper 11 bits of the captured data if using this mode.  

    Regards,
