LOW SKEW, 1-TO-5
DIFFERENTIAL-TO-2.5V/3.3V LVPECL FANOUT BUFFER
APPLICATION INFORMATION
FIGURE 2. SINGLE ENDED SIGNAL DRIVING DIFFERENTIAL INPUT
Figure 2 shows how the differential input can be wired to accept
single ended levels. The reference voltage V_REF = V
CC/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
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS
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
CC = 3.3V, V_REF should
be 1.25V and R2/R1 = 0.609.

INPUTS:
CLK INPUT:
For applications not requiring the use of a clock input, it can
be left floating. Though not required, but for additional
protection, a 1k
Ω resistor can be tied from the CLK input to
ground.
CLK/nCLK INPUT:
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
Ω resistor can be tied from
CLK to ground.
LVCMOS CONTROL PINS:
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1k
Ω resistor can be used.
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
OUTPUTS:
LVPECL OUTPUT
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.
