Optimized for clock distribution in DDR (Double Data Rate)
SDRAM applications requiring improved output crosspoint
voltage
Operating frequency: 60MHz to 220MHz
Very low skew:
– <100ps for PC1600 - PC2700
– <75ps for PC3200
Very low jitter:
– <75ps for PC1600 - PC2700
– <50ps for PC3200
2.5V AVDD and 2.5V VDDQ for PC1600-PC2700
2.6V AVDD and 2.6V VDDQ for PC3200
CMOS control signal input
Test mode enables buffers while disabling PLL
Low current power-down mode
Tolerant of Spread Spectrum input clock
Available in 48-pin TSSOP and TVSOP, 40-pin VFQFPN, and 56-
pin VFBGA packages
DESCRIPTION:
TheCSPT857DisaPLLbasedclockdriverthatactsasazerodelaybuffer
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.
TheCSPT857Drequiresnoexternalcomponentsandhasbeenoptimised
forverylowI/Ophaseerror,skew,andjitter,whilemaintainingfrequencyand
duty cycleovertheoperatingvoltageandtemperaturerange.TheCSPT857D,
designedforuseinbothmoduleassembliesandsystemmotherboardbased
solutions,providesanoptimumhigh-performanceclocksource.
The CSPT857D 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, SSTVN16859, DDR1 register, provides complete
solution for DDR1 DIMMs
