FEATURES:

DESCRIPTION:

• Ref input is 5V tolerant

TheIDT5V995isahighfanout3.3VPLLbasedclockdriverintendedfor

highperformancecomputinganddata-communicationsapplications.Akey

featureoftheprogrammableskewistheabilityofoutputstoleadorlagthe

REFinputsignal. TheIDT5V995haseightprogrammableskewoutputsin

fourbanksof2.Skewiscontrolledby3-levelinputsignalsthatmaybehard-

wired to appropriate HIGH-MID-LOW levels.

• 4 pairs of programmable skew outputs

• Low skew: 185ps same pair, 250ps all outputs

• Selectable positive or negative edge synchronization:

Excellent for DSP applications

• Synchronous output enable

• Input frequency: 2MHz to 200MHz

• Output frequency: 6MHz to 200MHz

• 3-level inputs for skew and PLL range control

• 3-level inputs for feedback divide selection multiply / divide

ratios of (1-6, 8, 10, 12) / (2, 4)

• PLL bypass for DC testing

• External feedback, internal loop filter

• 12mA balanced drive outputs

Thefeedbackinputallowsdivide-by-functionalityfrom1to12throughthe

use of the DS[1:0] inputs. This provides the user with frequency

multiplication from 1 to 12 without using divided outputs for feedback.

WhenthesOEpinisheldlow,alltheoutputsaresynchronouslyenabled.

However, if sOE is held high, all the outputs except 2Q0 and 2Q1 are

synchronouslydisabled. TheLOCKoutputassertstoindicatewhenPhase

Lock has been achieved.

Furthermore,whenPEisheldhigh,alltheoutputsaresynchronizedwith

thepositiveedgeoftheREFclockinput.WhenPEisheldlow,alltheoutputs

are synchronized with the negative edge of REF. The IDT5V995 has

LVTTL outputs with 12mA balanced drive outputs.

• Low Jitter: <100ps cycle-to-cycle

• Power-down mode

• Lock indicator

• Available in TQFP package
