DS90UB954-Q1: Regarding alternative DS90UB954-Q1

Kyosuke Tanino

Part Number: DS90UB954-Q1

The customer is currently considering DS90UB936TRGZRQ1 as a replacement for DS90UB954-Q1.

Therefore, we have the following questions

Can communication be guaranteed even if the transmitter IC (953) remains the same?
Do I need to change the set? (Transmitter IC also needs to be changed to 935)
The external appearance is the same, but is the chip also the same? Are they different?
If they are the same, how is the performance difference determined?
If not, do you have the results of the noise test?

Hello Kyosuke,

Yes

No, 953 can still be used but CSI-2 throughput max rate will be based on the lower spec device (2.528Gbps per RX channel)

The device is the same; just qualified for lower CSI-2 throughput per RX channel

Kyosuke Tanino said:

This is internal TI confidential information

N/A - link performance is identical

Best Regards,

Casey

Thanks Casey!

I have tow questions.

Is there any difference in noise performance between DS90UB9541 and DS90UB936?
Can you make a comparison chart between DS90UB954 and DS90UB936?
