PCI EXPRESS CLOCK GENERATOR
PRELIMINARY
OUTPUT DRIVER CURRENT
The ICS841S04I outputs are HCSL current drive with the cur-
rent being set with a resistor from I
REF to ground. For a 50Ω
pc board trace, the drive current would typically be set with a
R
REF of 475Ω which products an IREF of 2.32mA. The IREF is
multiplied by a current mirror to an output drive of 6*2.32mA
or 13.92mA. See Figure 3 for current mirror and output drive
details.

INPUTS:
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:
DIFFERENTIAL OUTPUT s
All unused differential 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.
