Hi team,
My customer wants to crify whether TUSB9261 datasheet Table 5 SPI_DATA_IN Setup time value 22ns is correct.
The customer says as follows.
General SPI-FLASH device outputs data on the falling edge of the clock and its output maximum
delay time is generaly 8ns. TUSB9261 receives a data on the rising edge of the clock.
When Cycle time SPICLK is 53.3ns, the partner SPI-FLASH device output delay time must be maximum
4.65ns(=53.3ns/2 - 22ns). So, general SPI-FLASH device can not be TUSB9261 partner.
Is the setup time value 22ns is a typo? If it is typo, how much is the maximum setup time?
Please let me know the answers.
Best regards,
Fumio Nakano
