1.8V PHASE LOCKED LOOP  
IDTCSPU877  
DIFFERENTIAL 1:10 SDRAM  
CLOCK DRIVER  
FEATURES:  
DESCRIPTION:  
• 1 to 10 differential clock distribution  
• Optimized for clock distribution in DDR2 (Double Data Rate)  
SDRAM applications  
TheCSPU877isaPLLbasedclockdriverthatactsasazerodelaybuffer  
to distribute one differential clock input pair(CLK, CLK ) to 10 differential  
output pairs (Y[0:9], Y[0:9]) and one differential pair of feedback clock output  
(FBOUT,FBOUT). Externalfeedbackpins(FBIN,FBIN)forsynchronization

500μA.  
• Operating frequency: 125MHz to 340MHz  
• Very low skew: 40ps  
• Very low jitter: 40ps  
• 1.8V AVDD and 1.8V 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 52-Ball VFBGA and 40-pin VFQFPN packages  
TheCSPU877requiresnoexternalcomponentsandhasbeenoptimised  
forverylowphaseerror,skew,andjitter,whilemaintainingfrequencyandduty  
cycle over the operating voltage and temperature range. The CSPU877,  
designedforuseinbothmoduleassembliesandsystemmotherboardbased  
solutions,providesanoptimumhigh-performanceclocksource.  
The CSPU877 is available in Commercial Temperature Range (0°C to  
+70°C). SeeOrderingInformationfordetails.  
APPLICATIONS:  
• Meets or exceeds JEDEC standard 82-8 for registered DDR2  
clock driver  
• Along with SSTU32864/A, DDR2 register, provides complete  
solution for DDR2 DIMMs
