3.3V Programmable Skew PLL Clock Driver

Features

Description

• PI6C3Q99X family provides following products:

PI6C3Q991:32-pinPLCCversion

PI6C3Q993:28-pinQSOPversion

• Inputs are 5V Tolerant

ThePI6C3Q99Xfamily,ahigh-fanout3.3VPLL-basedclockdriver,

isintendedforhigh-performancecomputinganddata-communica-

tion applications. A key feature of the programmable skew is the

abilityofoutputstoleadorlagtheREFinputsignal.ThePI6C3Q991

has 8 programmable skew outputs in 4 banks of 2, while the

PI6C3Q993 has 6 programmable skew outputs and 2 zero skew

outputs. Skew is controlled by 3-level input signals that may be

hard-wiredtoappropriateHIGH-MID-LOWlevels.

• 4 pairs of programmable skew outputs

• Low skew: 200ps same pair; 250ps all outputs

• Selectable positive or negative edge synchronization:

Excellent for DSP applications

• Synchronous output enable

When the GND/sOE pin is held LOW, all the outputs are synchro-

nously enabled. However, if GND/sOE is held HIGH, all outputs

except 3Q0 and 3Q1 are synchronously disabled. Furthermore,

• Input frequency: 3.75 MHz to 85 MHz

• Output frequency: 15 MHz to 85MHz

• 2x, 4x, 1/2, and 1/4 outputs

LOW, all outputs are synchronized with the negative edge of REF.

Both devices have LVTTL outputs with 12mA balanced drive

outputs.

• 3-level inputs for skew and PLL range control

• PLL bypass for DC testing

• Externalfeedback,internalloopfilter

• 12mA balanced drive outputs

• LowJitter:<200pspeak-to-peak

• Industrial temperature range

• Availablein32-pinPLCCand28-pinQSOP
