INFORMATION

FEATURES:

DESCRIPTION:

• Phase-Lock Loop Clock Distribution for Applications ranging

from 10MHz to 133MHz operating frequency

• Distributes one clock input to two banks of four outputs

• Separate output enable for each output bank

• External feedback (FBK) pin is used to synchronize the outputs

to the clock input

TheIDT2308Bisahigh-speedphase-lockloop(PLL)clockmultiplier.Itis

designedtoaddresshigh-speedclockdistributionandmultiplicationapplica-

tions.Thezerodelayisachievedbyaligningthephasebetweentheincoming

clockandtheoutputclock,operablewithintherangeof10to133MHz.

TheIDT2308Bhastwobanksoffouroutputseachthatarecontrolledviatwo

selectaddresses.Byproperselectionofinputaddresses,bothbankscanbe

put in tri-state mode. In test mode, the PLL is turned off, and the input clock

directlydrives theoutputs forsystemtestingpurposes.Intheabsenceofan

inputclock,theIDT2308Benterspowerdown,andtheoutputsaretri-stated.

Inthis mode, the device willdrawless than25µA.

• Output Skew <200 ps

• Low jitter <200 ps cycle-to-cycle

• 1x, 2x, 4x output options (see table):

– IDT2308B-1 1x

– IDT2308B-2 1x, 2x

– IDT2308B-3 2x, 4x

– IDT2308B-4 2x

The IDT2308B is available in six unique configurations for both pre-

scaling and multiplication of the Input REF Clock. (See available options

table.)

– IDT2308B-1H, -2H, and -5H for High Drive

• No external RC network required

• Operates at 3.3V VDD
