DESCRIPTION:
The CSPT857C is a PLL based clock driver that acts as a zero delay buffer
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
). 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
approximately 20MHz, the device will enter power down mode. In this mode,
the receivers are disabled, the PLL is turned off, and the output clock drivers
are tristated, resulting in a current consumption of less than 200
μ
A.
The CSPT857C requires no external components and has been optimsed
for very low I/O phase error, skew, and jitter, while maintaining frequency and
duty cycle over the operating voltage and temperature range. The CSPT857C,
designed for use in both module assemblies and systemmotherboard based
solutions, provides an optimumhigh-performance clock source.
The CSPT857C is available in Commercial Temperature Range (0
°
C to
+70
°
C) and Industrial Temperature Range (-40
°
C to +85
°
C). See Ordering
Information for details.
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
