SN65MLVD048: Unused inputs to MLVDS receiver

Part Number: SN65MLVD048

How should the unused MLVDS receive buffer inputs (A, B) be strapped to assure the buffer will not oscillate?

    Hello,

    You can leave them open. Also leave FSEN pin open, since it is pulled high internally and when left open will set the receiver to Type-2. With Type-2 as long as you don't have differential noise in excess of 50 mV at the A/B inputs, the output will be a stable low and will not oscillate.
