Part Number: SN65LVCP408
Other Parts Discussed in Thread: LMH0302, , LMH0344

Hello,

Our customer is using SN65LVCP408 to implement the 1.485Gbps SDI crosspoint. The input signal comes from LMH0344 and the output signal leaves to LMH0302.

The question is that there is no signal comes out from SN65LVCP408. Would you please review the schematic or give some advice? thanks very much.SDI schematics.pdf

Hi,

Are you using I2C to control the LVCP408?

Did you "reset" the LVCP408 after power-up?

Have you been able to read and write I2C registers?

I did not see anything in the schematic which would prevent the LVCP408 outputs from switching.

Regards,

Lee
