DS90UB964-Q1: DS90UB964+913 program

Part Number: DS90UB964-Q1

We also have a 913 camera, paired with TI 914, stable in diagram printout, but occasionally no figure with normal IIC communication when paired with TI 964.

With external power supply by disconnecting the POC power supply, diagram printout is stable with TI 964 in test, so I have two questions:

1. So if paired with different deserializer, is the POC filter different?

2. In addition, when paired with different deserializer, is the cut off frequency different?

Thanks.

Hello,

Yes, the Some devices run on different Back channel frequency and the PoC Filter should be designed to cover the complete frequency range from half of BC-frequency to the max FC-frequency.
So you need to optimize your PoC filter according to the used device and used BC datarate.

Hi Hamzeh,

Thanks for your answer. The customer has further questions need your help.

Based on the current solution of the customer, should the POC plan be based on the BC data rate of 913 or 964?

Thanks.

Hello Annie,

yes the PoC should start from the 913 BC Frequency/2 = ~1MHz to the max forward channel frequency (1GHz)
