HIGH SPEED, ÷4 DIFFERENTIAL-TO-
3.3V, 5V LVPECL/ECL CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS873033 is a high speed, high perfor-
ICS mance Differential-to-3.3V, 5V LVPECL/ECL
HiPerClockS™ Clock Generator a n d a m e m b e r o f t h e
HiPerClockS ™ family of High Performance
Clock Solutions from ICS. The ICS873033
is characterized to operate from either a 3.3V or a 5V
power supply.
FEATURES
One differential 3.3V, 5V LVPECL / ECL output
One differential PCLK, nPCLK input pair
PCLK, nPCLK pair can accept the following
differential input levels: LVPECL, LVDS, CML, SSTL
Input frequency: 3.2GHz (maximum)
Translates any single ended input signal to 3.3V
LVPECL levels with resistor bias on nPCLK input
• Additive phase jitter, RMS: 0.20ps (typical)
LVPECL mode operating voltage supply range:
VCC = 3.0V to 5.5V, VEE = 0V
ECL mode operating voltage supply range:
VCC = 0V, VEE = -5.5V to -3.0V
-40°C to 85°C ambient operating temperature
Available in both standard and lead-free RoHS-compliant
packages
