shows how the differential input can be wired to accept
single ended levels. The reference voltage V_REF = V
/2 is
generated by the bias resistors R1, R2 and C1. This bias circuit
should be located as close as possible to the input pin. The ratio

of R1 and R2 might need to be adjusted to position the V_REF in
the center of the input voltage swing. For example, if the input
clock swing is only 2.5V and V

= 3.3V, V_REF should be 1.25V
and R2/R1 = 0.609.

For applications not requiring the use of a clock input, it can
be left floating. Though not required, but for additional
protection, a 1k

ground.

For applications not requiring the use of the differential input,
both CLK and nCLK can be left floating. Though not required,
