SNLS696A April 2021 – May 2021 TSER953
The CLK_OUT/IDX pin serves two functions. At power up, the voltage on the IDX pin is compared to VDD and the ratio sets various parameters for configuration of the TSER953. After the TSER953 is configured, the CLK_OUT/IDX pin switches over to a clock source, intended to provide a reference clock to the image sensor. A minimum load impedance at the CLK_OUT/IDX pin of 35 kΩ is required when using the CLK_OUT function.
