TUSB9261: question for clock and flash

Sunny Qin

Part Number: TUSB9261

Hi Team,

Can TUSB9261 use 25MHz crystal, i saw most use 40M, but this is no 40M crystal in my customer?

the second question is: do this part must need a flash for SPI? if so, what is the requirement for the flash?

Thanks very much.

Regards, Sunny

Only 40 MHz is supported. (Apparently, this was changed in revision G of the datasheet, and I'm sure there was a reason for that.)

The SPI flash is needed for the firmware. Its requirements are described in section 8.2.2.4.
