SN75LVDS82: Operating conditions

Part Number: SN75LVDS82
Other Parts Discussed in Thread: SN65LVDS822

Hi Team,

We would need your help regarding a LVDS to RGB transceiver, the SN75LVDS82DGGR that we are using it in one of our boards.

We are trying to connect a display that requires a frequency of 7MHz for the pixel clock frequency and we were wandering if this would work. There is a note in the datasheet that the “Pixel Clock Frequency Range of 31 MHz to 68 MHz” but nothing in the Operating condition table of the datasheet.

Can you please help us with an answer to this?

Hello RJ,

SN75LVDS82 will not support that low of a PCLK frequency and I don't believe we have any single-chip solution for this conversion however you could use DS90UB927-Q1 + DS90UB926-Q1 for this purpose

Best Regards,

Casey

Hey Casey,

Would the sn65lvds822 work given the range from 4-54MHz?

Appreciate your feedback on this.

Hey RJ,

That's a good find and yes it does look like it would be a good fit for your application. I must have missed that in my previous search

Best Regards,
