DS90UB954-Q1: Connected to ub933 w/ EX OSC mode at 48MHz, while 954 is operating at 25MHz. is this OK?

Part Number: DS90UB954-Q1

Hi team,

My customer is asking about the configuration of 954-933. 933 is operating with external oscillator mode at 48MHz clock in and output divided by 2, so 24MHz to ISP.

but while 954 is opearting at 25MHz with REFCLK. so does this work correctly? or should be at the same frequency both like 24MHz.

NY,
this can work. the external 25M clock of UB954 mainly is for CSI2 port. the UB954 can recover the clock from the input data which is not same clock domain with CSI2 clock, but both can be compatible inside UB954.

regards,
Steven

Steven,

thank you for the reply.
I understand about external 25M clock of UB954.

best regards
