LMX2615-SP: Output Pull-up

Steve Widener

Part Number: LMX2615-SP

We have need to DC couple the RFoutB to the LVDS receiver. In doing this the parallel load resistance will be 53 ohms but the resultant pullup voltage at RFoutB will only be 2.4V, is this okay?

Hello Steve,

If the DC voltage (average of Voh + Vol) at the output of the LMX2615-SP falls within the input Vcm (common mode voltage) of the LVDS receiver then DC coupling is okay.

Thanks,

Vibhu
