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

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:
