DS90UB914A-Q1: RX input high and low frequency measurements

Alan O

Part Number: DS90UB914A-Q1
Other Parts Discussed in Thread: DS90UB960-Q1

Hello,

The DS90UB960-Q1 has RX_FREQ_HIGH and RX_FREQ_LOW counter registers to report the measured frequency of the FPD link. Does DS90UB914A-Q1 deserializer have such registers, or another way to infer or derive the frequency?

Thanks,
Alan

DS90UB914A deserializer does not have such a register as 914A does not use an external reference clock. Since 960 uses an external reference clock, the input data rate can be measured (using the external clock as reference pretty accurately). 914A on the other hand is completely reference-less so cannot measure the incoming data rate

Thanks

Vijay
