ESCRIPTION
The ICS87339-01 is a low skew, high perfor-
mance Differential-to-3.3V LVPECL / ECL Clock
G e n e r a t o r / D i v i d e r a n d a m e m b e r o f t h e
HiPerClockSTM family of High Performance Clock
Solutions from ICS. The ICS87339-01 has one
differential clock input pair. The CLK, nCLK pair can accept
most standard differential input levels. The clock enable is
internally synchronized to eliminate runt pulses on the
outputs during asynchronous assertion/deassertion of the
clock enable pin.
Guaranteed output and part-to-part skew characteristics
make the ICS87339-01 ideal for clock distribution applications
demanding well defined performance and repeatability.
F
EATURES
2 divide by 2/4 differential 3.3V LVPECL outputs;
2 divide by 4/6 differential 3.3V LVPECL outputs
1 differential CLK, nCLK input pair
CLK, nCLK pair can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
Maximum input frequency: 1GHz
Translates any single ended input signal (LVCMOS, LVTTL,
GTL) to LVPECL levels with resistor bias on nCLK input
Output skew: 50ps (maximum)
Part-to-part skew: 200ps (maximum)
