differential drivers as shown in Figures 3 and 4. SY55854U

expects the inputs to be terminated, and that good high

speed design practices be adhered to. SY55854U inputs

are designed to accept a termination resistor between the

true and complement inputs of a differential pair. 0402 form

factor chip resistors will fit with some trace fanout.
