ICS83940DYI REV. A FEBRUARY 21, 2007
ICS83940DI
LOW SKEW, 1-TO-18 LVPECL-TO-LVCMOS/LVTTL FANOUT BUFFER
LVPECL CLOCK INPUT INTERFACE
The PCLK /nPCLK accepts LVPECL, CML, SSTL and other
differential signals. Both V
SWING
and V
OH must
meet the V
PP and
V
CMR
input requirements. Figures 2A to 2F show interface
examples for the HiPerClockS PCLK/nPCLK input driven by
the most common driver types. The input interfaces suggested
here are examples only. If the driver is from another vendor,
use their termination recommendation. Please consult with the
vendor of the driver component to confirm the driver termination
requirements.
