CLOCK DRIVER

FEATURES:

DESCRIPTION:

• 2.5VDD

The IDT5T9821is a 2.5VPLLdifferentialclockdriverintendedforhigh

performance computing and data-communications applications. The

IDT5T9821has sixdifferentialoutputs insixbanks,includingadedicated

differentialfeedback. The redundantinputcapabilityallows fora smooth

change overtoa secondaryclocksource whenthe primaryclocksource

isabsent.

• 6 pairs of outputs

• Low skew: 100ps all outputs at same interface level, 250ps all

outputs at different interface levels

• Selectable positive or negative edge synchronization

• Tolerant of spread spectrum input clock

• Synchronous output enable

TheclockdrivercanbeconfiguredthroughtheuseofJTAG/I²Cprogram-

ming. An internal EEPROM will allow the user to save and restore the

configurationofthedevice.

• Selectable inputs

• Input frequency: 4.17MHz to 250MHz

• Output frequency: 12.5MHz to 250MHz

• Internal non-volatile EEPROM

The feedbackbankallows divide-by-functionalityfrom1to12through

theuseofJTAGorI Cprogramming. Thisprovidestheuserwithfrequency

• JTAG or I C bus serial interface for programming

multiplication1to12withoutusingdividedoutputsforfeedback. Eachoutput

bank also allows for a divide-by functionality of 2 or 4.

• Hot insertable and over-voltage tolerant inputs

• Feedback divide selection with multiply ratios of (1-6, 8, 10, 12)

• Selectable HSTL, eHSTL, 1.8V/2.5V LVTTL, or LVEPECL input

interface

• Selectable HSTL, eHSTL, or 1.8V/2.5V LVTTL output interface for

each output bank

• Selectable differential or single-ended inputs and six differen-

tial outputs

• PLL bypass for DC testing

• External differential feedback, internal loop filter

• Low Jitter: <75ps cycle-to-cycle, all outputs at same interface

level: <100ps cycle-to-cycle all outputs at different interface

levels

The IDT5T9821 features a user-selectable, single-ended or differential

input to six differential outputs. The differential clock driver also acts as a

translatorfromadifferentialHSTL,eHSTL,1.8V/2.5VLVTTL,LVEPECL,or

single-ended1.8V/2.5VLVTTLinputtoHSTL,eHSTL,or1.8V/2.5VLVTTL

outputs. EachoutputbankcanbeindividuallyconfiguredtobeeitherHSTL,

eHSTL,2.5VLVTTL,or1.8VLVTTL,includingthefeedbackbank. Also,each

clockinputcanbeindividuallyconfiguredtoaccept2.5VLVTTL,1.8VLVTTL,

ordifferentialsignals. Theoutputscanbesynchronouslyenabled/disabled.

Furthermore,alltheoutputscanbesynchronizedwiththepositiveedge

of the REF clock input. or the negative edge of REF.

• Power-down mode

• Lock indicator

• Available in VFQFPN package
