DESCRIPTION

• Ref input is 5V tolerant

TheIDT5V994isahighfanout3.3VPLLbasedclockdriverintendedfor

highperformancecomputinganddata-communicationsapplications.Akey

REFinputsignal. TheIDT5V994haseightprogrammableskewoutputsin

fourbanksof2.Skewiscontrolledby3-levelinputsignalsthatmaybehard-

wired to appropriate HIGH-MID-LOW levels.

• 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

• Input frequency: 17.5MHz to 133MHz

• Output frequency: 17.5MHz to 133MHz

• 2x, 4x, 1/2, and 1/4 outputs (of VCO frequency)

• 3-level inputs for skew control

• PLL bypass for DC testing

• External feedback, internal loop filter

• 12mA balanced drive outputs

WhenthesOEpinisheldlow,alltheoutputsaresynchronouslyenabled.

However, if sOE is held high, all the outputs except 3Q0 and 3Q1 are

synchronously disabled.

Furthermore, whenthePEisheldhigh, alltheoutputsaresynchronized

with the positive edge of the REF clock input. When PE is held low, all the

outputs are synchronized with the negative edge of REF. The IDT5V994

has LVTTL outputs with 12mA balanced drive outputs.

• Low Jitter: <200ps cycle-to-cycle

• Available in PLCC and TQFP packages
