May I ask which serial device is better for ds90uh940n-q1? It is 720P for the customer. Thank you!

Hello Frank,

are you looking for a suitable Serializer?

what is the Interface at the source side?

Dear Hamzeh

Yes, I need a Serializer device，The client is currently using a DVP parallel interface，Please recommend it.

By the way, I have two questions:

1. If it is a single coaxial transmission, does the coaxial line need to be grounded, and does the signal line need to be connected with capacitors?

2. If it is equipped with POC function, is there any peripheral POC circuit in the circuit, and does the signal line need to be connected with capacitors in series?

Thank you very much!

Hello Frank,

You can use the DS90UH925. In this Serializer a RGB888 + VS, HS, DE and I2S Audio are Supported. The PCLK is 5 to 85 MHz.

1) If you are using A SER-DES pair which supports Coax, your coax cable shall shield shall be connected to the PCB GND, and the signal line shall be connected with AC-Coupling capacitors on the PCBs at both ends.

2) Yes, if you are using Power over Coax then you will need PoC filter circuits on the PCBs at both ends.

Dear Hamzeh

Two questions:

1.Does DS90UH925 support single coaxial cable transmission signal？

2.Can ds90uh940n-q1 be matched with ds90ub933-q1？

Thank you！

Frank,

1) 925 does not support Coax, only STP.

2) unfortunately not, 933 is not compatible with 940.

Can you tell me what are you planning? are you looking for a compatible CSI-2 Deserializer to the 933? If yes, you can use the DS90UB936 or the DS90UB954.

Dear Hamzeh

Sorry, I made a mistake

I mean can you match 940 with 933?

The customer's product is DMS，The end customer interface is 940

Hi Frank,

As I said, 933 is not compatible with 940.
