TLV3601EVM: output signal of comparator is attenuated which is not able to recognize by TDC

Part Number: TLV3601EVM
Other Parts Discussed in Thread: TLV3601, TDC7201

We are using TLV3601/03 EVM for ToF measurement. 

Detector output signal connected to Non inverting terminal and a ref voltage at inverting terminal of TLV3601.The out of TLV3601 is connected to TDC circuit as Stop pulse. 

Issue - TLV3601 output signal (around 2V ) is highly attenuated (around 100 mV) while connecting to STOP pin of TDC  and TDC is not consider it at transition pulse for time measurement. 

Further few more clarifying questions: 

  • TLV3601/3 EVM board have few zero ohm resistors as per EVM Schematic. Which are to be populated in case of TLV3601DCK comparator IC.
  • Any care to be taken with regard to reference voltage for TLV3601
