Functional Description
ASM5P23S08A is a versatile, 3.3V zero-delay buffer
designed to distribute high-speed clocks. It is available in a
16 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 ASM5P23S08A has two banks of four outputs each,
which can be controlled by the select inputs as shown in
the Select Input Decoding Table. The select input also
allows the input clock to be directly applied to the outputs
for chip and system testing purposes.
Multiple ASM5P23S08A 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
700pS.
The
ASM5P23S08A
is
available
in
five
different
configurations
(Refer
“ASM5P23S08A
Configurations
Table). The ASM5P23S08A-1 is the base part, where the
output frequencies equal the reference if there is no
counter in the feedback path. The ASM5P23S08A-1H is
the high-drive version of the -1 and the rise and fall times
on this device are faster.
The ASM5P23S08A-2 allows the user to obtain 2X and 1X
frequencies on each output bank. The exact configuration
and output frequencies depends on which output drives the
feedback pin. The ASM5P23S08A-3 allows the user to
obtain 4X and 2X frequencies on the outputs.
The ASM5P23S08A-4 enables the user to obtain 2X clocks
on all outputs. Thus, the part is extremely versatile, and
can be used in a variety of applications.
The ASM5P23S08A-5H is a high-drive version with REF/2
on both banks
