General Description

The ICS853S310I is a low skew, high performance 1-to-8

Differential-to-3.3V LVPECL/ECL Fanout Buffer. The PCLKx,

nPCLKx pairs can accept LVPECL, LVDS, CML and SSTL

differential input levels. The ICS853S310I is characterized to operate

from a 3.3V power supply. Guaranteed output and part-to-part skew

characteristics make the ICS853S310I ideal for those clock

distribution applications demanding well defined performance and

repeatability.

Features

• Eight differential 3.3V LVPECL/ECL outputs

• Two selectable differential input pairs

• PCLKx, nPCLKx pairs can accept the following

differential input levels: LVPECL, LVDS, CML, SSTL

• Maximum output frequency: 2GHz

• Translates any single-ended input signal to 3.3V LVPECL levels

with resistor bias on nPCLKx input

• Output skew: 20ps (typical)

• Propagation delay: 825ps (typical)

• Additive phase jitter, RMS: 0.14ps (typical)

• LVPECL mode operating voltage supply range:

VCC = 3.0V to 3.8V, VEE = 0V

• ECL mode operating voltage supply range:

VCC = 0V, VEE = -3.0V to -3.8V

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

• Available lead-free (RoHS 6) package
