ICS853210
LOW SKEW, DUAL, 1-TO-5
DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS853210 is a low skew, high perfor-
ICS
mance dual 1-to-5 Differential-to-2.5V/3.3V
HiPerClockS™ _{LVPECL/ECL Fanout Buffer and a member of}
the HiPerClockS™family of High Performance
Clock Solutions from ICS. The ICS853210
is characterized to operate from either a 2.5V or a 3.3V
power supply. Guaranteed output and par t-to-par t skew
characteristics make the ICS853210 ideal for those clock
distribution applications demanding well defined perfor-
mance and repeatability.
FEATURES
• 2 differential 2.5V/3.3V LVPECL / ECL bank outputs
• 2 differential clock input pairs
• PCLKx, nPCLKx pairs can accept the following
differential input levels: LVPECL, LVDS, CML, SSTL
• Maximum output frequency: >3GHz
• Translates any single ended input signal to 3.3V
LVPECL levels with resistor bias on nPCLKx input
• Output skew: 13ps (typical)
• Part-to-part skew: 85ps (typical)
• Propagation delay: 485ps (typical)
• LVPECL mode operating voltage supply range:
V_CC = 2.375V to 3.8V, V_EE = 0V
• ECL mode operating voltage supply range:
V = 0V, V = -2.375V to -3.8V
CC
EE
• -40°C to 85°C ambient operating temperature
• Pin compatible with MC100EP210 and MC100LVEP210
