Part Number: TDC1000-Q1

Can you help confirm the input capacitance required by CLKIN at pin 25 of TDC1000-Q1?

    Hello Delmore,

    Thanks for posting to the PS forum! This is not something that we have characterized on the TDC1000-Q1, on the EVM we use a 15pF capacitance clock so if the value is around this then it should work fine. Please ensure your external crystal oscillator frequency does not exceed 16MHz, and the voltage at the CLKIN pin does not exceed VIO+0.3V.

    Best,

    Isaac
