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

TheIDT23S08Tis ahigh-speedphase-lockloop(PLL)clockmultiplier.It

isdesignedtoaddresshigh-speedclockdistributionandmultiplicationapplica-

tions.Thezerodelayisachievedbyaligningthephasebetweentheincoming

• Output Skew <200 ps

• Low jitter <200 ps cycle-to-cycle

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

– IDT23S08T-1 1x

– IDT23S08T-2 1x, 2x

– IDT23S08T-3 2x, 4x

– IDT23S08T-4 2x

The IDT23S08T is available in six unique configurations for both pre-

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

table.)

– IDT23S08T-5 1/2x

• No external RC network required

• Operates at 2.5V VDD
