FUNCTIONAL BLOCK DIAGRAM
NOTE:
The Logic Detect (LD) powers down the device when a logic LOW is applied to both CLK and
CLK
.
DESCRIPTION:
The CSPU877D 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. OE, OS, and A
VDD
control the
power-down and test mode logic. When A
VDD
is grounded, the PLL is turned
off and bypassed for test mode purposes. When the differential clock inputs
(CLK,
CLK
) are both at logic low, this device will enter a low power-down mode.
In this mode, the receivers are disabled, the PLL is turned off, and the output
clock drivers are disabled, resulting in a current consumption device of less than
500
μ
A.
The CSPU877D requires no external components and has been optimsed
for very low phase error, skew, and jitter, while maintaining frequency and duty
cycle over the operating voltage and temperature range. The CSPU877D,
designed for use in both module assemblies and systemmotherboard based
solutions, provides an optimumhigh-performance clock source.
The CSPU877D is available in Commercial Temperature Range (0
°
C to
+70
°
C). See Ordering Information for details.
APPLICATIONS:
Meets or exceeds JEDEC standard 82.8 for registered DDR2
clock driver
Along with SSTU32864/65/66, DDR2 register, provides complete
solution for DDR2 DIMMs
