DS90UB933-Q1: tTCIH spec definition

Part Number: DS90UB933-Q1

Hello Team,

I would like to know the definition of tTCIH spec of the datasheet.

I wrote below picture. Which ① or ② is tTCIH?

Thanks,

Yuta Kurimoto

  • Hi Yuta,

    The t_TCIH parameter is the transmit clock input high time. It is the time the clock signal remains HIGH (at least 80% of VDD). As a result, the t_TCIH parameter would match ① in your figure.

    Best,
