DESCRIPTION:
TheCSPT857CisaPLLbasedclockdriverthatactsasazerodelaybuffer
todistributeonedifferentialclockinputpair(CLK,CLK)to10differentialoutput
pairs(Y[0:9],Y[0:9])andonedifferentialpairoffeedbackclockoutput(FBOUT,
FBOUT). External feedback pins (FBIN, FBIN) for synchronization of the
outputs to the input reference is provided. A CMOS Enable/Disable pin is
available for low power disable. When the input frequency falls below
approximately20MHz,thedevicewillenterpowerdownmode. Inthismode,
the receivers are disabled, the PLL is turned off, and the output clock drivers
aretristated,resultinginacurrentconsumptionoflessthan200
A.
TheCSPT857Crequiresnoexternalcomponentsandhasbeenoptimised
forverylowI/Ophaseerror,skew,andjitter,whilemaintainingfrequencyand

designedforuseinbothmoduleassembliesandsystemmotherboardbased
solutions,providesanoptimumhigh-performanceclocksource.
The CSPT857C is available in Commercial Temperature Range (0°C to
+70°C) and Industrial Temperature Range (-40°C to +85°C). See Ordering
Informationfordetails.
APPLICATIONS:
Meets or exceeds JEDEC standard JESD 82-1A for registered
DDR clock driver
Meets proposed DDR1-400 specification
For all DDR1 speeds: PC1600 (DDR200), PC2100 (DDR266),
PC2700 (DDR333), PC3200 (DDR400)
Along with SSTV16857, SSTVF16857, SSTV16859, SSTVM16859,
SSTVF16859, DDR1 register, provides complete solution for
DDR1 DIMMs
