2.5V PHASE LOCKED LOOP  
DIFFERENTIAL 1:10 SDRAM  
CLOCK DRIVER  
IDTCSPT857/A  
FEATURES:  
DESCRIPTION:  
• Optimized for clock distribution in DDR (Double Data Rate)  
SDRAM applications  
The CSPT857 is a PLL based clock driver that acts as a zero delay buffer  
todistributeonedifferentialclockinputpair(CLK,CLK)to10differentialoutput  
pairs(Y[0:9],Y[0:9])andonedifferentialpairoffeedbackclockoutput(FBOUT,  
FBOUT). External feedback pins (FBIN, FBIN) for synchronization of the  
• Operating frequency: 60MHz to 200MHz  
• Standard speed: PC1600 (DDR200), PC2100 (DDR266)  
• A speed: PC1600 (DDR200), PC2100 (DDR266), PC2700 (DDR333) outputs to the input reference is provided. A CMOS Enable/Disable pin is  
• 1 to 10 differential clock distribution  
• Very low skew (<100ps)  
• Very low jitter (<75ps)  
• 2.5V AVDD and 2.5V VDDQ  
• 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 56-pin VFBGA packages  
available for low power disable. When the output frequency falls below  
approximately20MHz,thedevicewillenterpowerdownmode. Inthismode,
