DS90UB913A-CXEVM

Other Parts Discussed in Thread: DS90UB913A-CXEVM

I would like to conifrm the external oscillator of DS90UB913A-CXEVM.

In the schematic, there is CY25418, but there is not it on the EVM.

And in the BOM, there is the oscillator of 100MHz.

I have questions.

1. Isn't there CY25418 on the EVM, is there? Is there the oscillator only?

2. If the frequency of the oscillator is 100MHz, the pixel frequency is 200MHz, because there is the description of the relationship for these

    frequencies in the datasheet 28 page (In the 10 bit mode, ...... , that is, 72MHz.).

    I can not understand it, because this IC can support up to 100MHz pixel frequency.

    Is the frequecy of the oscillator correct? Or is my thought wrong?

Best regards,

Atsushi Yamauchi

    Hello Atsushi-san,

    This is a mistake in our EVM User's Guide. The external oscillator is populated as a 48 MHz oscillator (ECS-3963-480-BN-TR, 48MHz, DigiKey# XC1039CT-ND) on our 913A EVM, not 25 MHz or 100 MHz. This is being updated in the next revision of the User's Guide. My apologies for the confusion here.

    Thank you,

    Sean
