3.3V Programmable Skew PLL Clock Driver

SuperClock

Features

Description

ThePI6C3Q99Xfamilyisahighfanout3.3VPLLbasedclockdriver

intended for high performance computing and data-communica-

tions 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.Skewiscontrolledby3-levelinputsignalsthatmaybehard-

wiredtoappropriateHIGH-MID-LOWlevels.

PI6C3Q99X family provides following products:

PI6C3Q991:32-pinPLCCversion

PI6C3Q993:28-pinQSOPversion

Inputs are 5V I/O Tolerant

4 pairs of programmable skew outputs

Low skew: 200ps same pair, 250ps all outputs

Selectable positive or negative edge synchronization:

ExcellentforDSPapplications

Synchronous output enable

Output frequency: 3.75 MHz to 85 MHz

2x, 4x, 1/2, and 1/4 outputs

3 skew grades:

3-level inputs for skew and PLL range control

PLL bypass for DC testing

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

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

except3Q0and3Q1aresynchronouslydisabled.Furthermore,when

the V

/PE is held high, all the outputs are synchronized with the

CCQ

positive edge of the REF clock input. When V

/PE is held low,

devices have LVTTL outputs with 12mA balanced drive outputs.
