LOW SKEW, DUAL, PROGRAMMABLE 1-TO-2 DIFFERENTIAL-TO-LVDS, LVPECL FANOUT BUFFER

Integrated Device Technology 

LOW SKEW, DUAL, PROGRAMMABLE 1-TO-2 DIFFERENTIAL-

TO-LVDS, LVPECL FANOUT BUFFER

ICS854S204I

GENERAL DESCRIPTION

The ICS854S204I is a low skew, high performance

ICS

dual, programmable 1-to-2 Differential-to-LVDS,

HiPerClockS™ LVPECL Fanout Buffer and a member of t h e

HiPerClock S™ family of High Performance Clock

Solutions from IDT. The PCLKx, nPCLKx pairs can

accept most standard differential input levels. With the selection of

SEL_OUT signal, outputs can be selected be to either LVDS or

LVPECL levels. The ICS854S204I is characterized to operate

from either a 2.5V or a 3.3V power supply. Guaranteed out-

put and bank skew characteristics make the ICS854S204I

ideal for those clock distribution applications demanding well

defined performance and repeatability.

FEATURES

• Two programmable differential LVDS or LVPECL output banks

• Two differential clock input pairs

• PCLKx, nPCLKx pairs can accept the following differential

input levels: LVDS, LVPECL, SSTL, CML

• Maximum output frequency: 3GHz

• Translates any single ended input signal to LVDS levels

with resistor bias on nPCLKx inputs

• Output skew: 15ps (maximum)

• Bank skew: 15ps (maximum)

• Propagation delay: 500ps (maximum)

• Additive phase jitter, RMS: 0.15ps (typical)

• Full 3.3V or 2.5V power supply
