ICS87421AMI REV. A OCTOBER 3, 2007

GENERAL DESCRIPTION

The ICS87421I is a high perfor mance ÷1/÷2

Differential-to-LVDS Clock Generator and a mem-

ber of the HiPerClockS™ family of High Perfor-

mance Clock Solutions from IDT. The CLK, nCLK

pair can accept most standard differential input

levels. The ICS87421I is characterized to operate from a 3.3V

power supply. Guaranteed part-to-part skew characteristics

make the ICS87421I ideal for those clock distribution applica-

tions demanding well defined performance and repeatability.

FEATURES

• One differential LVDS output

• One differential CLK, nCLK input pair

• CLK, nCLK pair can accept the following differential input

levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL

• Maximum clock input frequency: 1GHz

• Translates any single ended input signal (LVCMOS, LVTTL,

GTL) to LVDS levels with resistor bias on nCLK input

• Part-to-part skew: 500ps (maximum)

• Propagation delay: 1.7ns (maximum)

• Additive phase jitter, RMS @ 155.52MHz: 0.17ps (typical)

• Full 3.3V operating supply

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

• Available in both standard (RoHS 5) and lead-free (RoHS 6)
