SN75LVDS82: About the CLKOUT output when the SHTDN is high.

Kengo.Y

Part Number: SN75LVDS82

Hi team,

Even if SHTDNpin is set to high, CLKOUT is not output.
Is there anything else I need to set?
Could you tell me your advice?

Sincerely.
Kengo.

Hi Kengo,

Are you following the power up and power down sequence described in the section "10.2.1.2.1" of the datasheet? What is your CLKIN frequency?

Hi Michael,

Thank you for your reply.

Yes.
My customer runs according to the power sequence but does not improve.

They use 36MHz.

Could you give me some advice?

Sincerely.
Kengo.

Thank you for sending me your schematic. How are you measuring your CLKIN signal? are you using a differential probe?
