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

CLK/nCLK I
For applications not requiring the use of the differential input,
both CLK and nCLK can be left floating. Though not required,
but for additional protection, a 1k
CLK to ground.
PCLK/nPCLK I
For applications not requiring the use of a differential input,
both the PCLK and nPCLK pins can be left floating. Though
not required, but for additional protection, a 1k
be tied from PCLK to ground.
LVCMOS C
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1k resistor can be used.

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
be 1.25V and R2/R1 = 0.609.

All unused LVPECL outputs can be left floating. We
recommend that there is no trace attached. Both sides of the
differential output pair should either be left floating or
terminated.
