ICS853011C

LOW SKEW, 1-TO-2

DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER

GENERAL DESCRIPTION

The ICS853011C is a low skew, high perfor-

ICS

mance 1-to-2 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 ICS853011C

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 ICS853011C ideal for those

clock distribution applications demanding well defined

perfor mance and repeatability.

FEATURES

• 2 differential 2.5V/3.3V LVPECL / ECL outputs

• 1 differential PCLK, nPCLK input pair

• PCLK, nPCLK pair can accept the following

differential input levels: LVPECL, LVDS, CML, SSTL

• Output frequency: 3GHz

• Translates any single ended input signal to 3.3V

LVPECL levels with resistor bias on nPCLK input

• Output skew: 5ps (typical)

• Part-to-part skew: TBD

• Propagation delay: 250ps (typical)

• LVPECL mode operating voltage supply range:

VCC = 2.375V to 3.8V, VEE = 0V

• ECL mode operating voltage supply range:

V = 0V, V = -3.8V to -2.375V

CC

EE

• -40°C to 85°C ambient operating temperature

• Pin compatible with MC100LVEP11 and SY100EP11U
