Functional Description
ASM5P2304B is a versatile, 3.3V zero-delay buffer
designed
to
distribute
high-speed
clocks
in
PC,
workstation, datacom, telecom and other high-performance
applications. It is available in an 8 pin package. The part
has an on-chip PLL, which locks to an input clock,
presented on the REF pin. The PLL feedback is required to
be driven to FBK pin, and can be obtained from one of the
outputs.
The
input-to-output
propagation
delay
is
guaranteed to be less than 250pS, and the output-to-output
skew is guaranteed to be less than 200pS.
The ASM5P2304B has two banks of two outputs each.
Multiple ASM5P2304B devices can accept the same input
clock and distribute it. In this case the skew between the
outputs of the two devices is guaranteed to be less than
500pS.
The
ASM5P2304B
is
available
in
two
different
configurations (Refer “ASM5P2304B Configurations Table).
The ASM5P2304B-1 is the base part, where the output
frequencies equal the reference if there is no counter in the
feedback path. The ASM5P2304B-1H is the high-drive
version of the -1 and the rise and fall times on this device
are much faster. The ASM5P2304B-2 allows the user to
obtain REF and 1/2X or 2X frequencies on each output
bank. The exact configuration and output frequencies
depend on which output drives the feedback pin.
