Vincent Lin

Part Number: TMUXHS221

Dear Sir:

Regarding the TMUXHS221 for PCIE REF CLK Application.

1. No use the DA Port.

DA+ pin is NC ( No connection) -Floating , Is it OK?

DA- pin is NC ( No connection) -Floating , Is it OK?

Incoming CLK connects to D+ / D-.

Forwarded CLK connects to DB+/ DB-

Are the above connections OK?

Please check to reply us asap.

Thanks a lot.

Hi Vincent,

Your circuitry for OEN pin is more complicated than normal. To clarify, OEN must be low for mux to be on.

Besides that, schematic looks good.

Best,

Stanton
