ICS8308AGI REV. B OCTOBER 16, 2007
ICS8308I
LOW SKEW, 1-TO-8 DIFFERENTIAL/LVCMOS-TO-LVCMOS FANOUT BUFFER
APPLICATION INFORMATION
Figure 1 shows how the differential input can be wired to accept
single ended levels. The reference voltage V_REF = V
DD
/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
FIGURE 1. SINGLE ENDED SIGNAL DRIVING DIFFERENTIAL INPUT
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
DD
= 3.3V, V_REF should be 1.25V
and R2/R1 = 0.609.
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS

Single Ended Clock Input
CLK
nCLK
VDD
INPUTS:
CLK INPUT
For applications not requiring the use of the test clock, 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 INPUTS
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:
LVCMOS OUTPUTS
All unused LVCMOS output can be left floating. There should be
no trace attached.
