ICS853111
LOW SKEW, 1-TO-10
DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS853111 is a low skew, high perfor-
,&6
mance 1-to-10 Differential-to-2.5V/3.3V LVPECL/
HiPerClockS™ _{ECL Fanout Buffer and a member of the}
HiPerClockS™ family of High Performance
Clock Solutions from ICS. The ICS853111
is characterized to operate from either a 2.5V or a 3.3V
power supply. Guaranteed output and part-to-part skew
characteristics make the ICS853111 ideal for those clock
distribution applications demanding well defined perfor-
mance and repeatability.
FEATURES
• 10 differential 2.5V/3.3V LVPECL / ECL outputs
• 2 selectable differential 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 nPCLK input
• Output skew: TBD
• Part-to-part skew: TBD
• Propagation delay: TBD
• LVPECL mode operating voltage supply range:
V_CC = 2.375V to 3.8V, V_EE = 0V
• ECL mode operating voltage supply range:
V_CC = 0V, V_EE = -3.8V to -2.375V
• -40°C to 85°C ambient operating temperature
• Pin compatible with MC100EP111 and MC100LVEP111
