Hi,

Can I use one of the GPIOs to send a clock from the DS90UB953A-Q1? If yes, what the frequency it can drive?

Hi Shmuel,

A PWM/CLK can be sent through GPIO. See below table for recommended operating constraints:

Ho Logan,

I want to use 1 GPIO of the 953 and connet it to a clock to a FPGA.

As I understand from your answer I can drive 25/12.5/5Mhz.

Is it depen the mode the 953 is working?

Hi Shmuel,

This table example is specifically for 4-Gbps synchronous mode with REFCLK = 25 MHz. See more details in the Forward Channel GPIO section of the datasheet.

Regards,

Logan
