3.3V Zero Delay Buffer
General Features
15MHz to 133MHz operating range, compatible
with CPU and PCI bus frequencies.
Zero input - output propagation delay.
Multiple low-skew outputs.
Output-output skew less than 250pS.
Device-device skew less than 700pS.
One input drives 9 outputs, grouped as
4 + 4 + 1(ASM5P2309A).
One input drives 5 outputs (ASM5P2305A).
Less than 200 pS cycle-to-cycle jitter is compatible
with Pentium® based systems.
Test Mode to bypass PLL (ASM5P2309A only,
Refer Select Input Decoding Table).
Available in 16pin 150-mil SOIC, 4.4 mm TSSOP
(ASM5P2309A), and in 8pin 150-mil SOIC
package (ASM5P2305A).
3.3V operation, advanced 0.35µ CMOS
technology.
Functional Description
ASM5P2309A is a versatile, 3.3V zero-delay buffer
designed to distribute high-speed clocks. It accepts one
reference input and drives out nine low-skew clocks. It is
available in a 16-pin package. The ASM5P2305A is the
eight-pin version of the ASM5P2309A. It accepts one
reference input and drives out five low-skew clocks.
The -1H version of the ASM5P23XXA operates at up to
133MHz frequencies, and has higher drive than the -1
devices. All parts have on-chip PLLs that lock to an input
clock on the REF pin. The PLL feedback is on-chip and is
obtained from the CLKOUT pad.
The ASM5P2309A 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 ASM5P2309A and ASM5P2305A 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.
All outputs have less than 200pS of cycle-to-cycle jitter.
The input and output propagation delay is guaranteed to be
less than 350pS, and the output to output skew is
guaranteed to be less than 250pS.
The ASM5P2309A and the ASM5P2305A are available in
two different configurations, as shown in the ordering
information table. The ASM5P2305A-1/ ASM5P2309A-1 is
the base part. The ASM5P2305A-1H/ ASM5P2309A-1H is
the high drive version of the -1 and its rise and fall times
are much faster than -1 part.

Notes:
1. This output is driven and has an internal feedback for the PLL. The load on this output can be adjusted to change the skew between the reference and the
output.
Zero Delay and Skew Control
All outputs should be uniformly loaded to achieve Zero
Delay between input and output. Since the CLKOUT pin is
the internal feedback to the PLL, its relative loading can
adjust the input-output delay.
For applications requiring zero input-output delay, all
outputs, including CLKOUT, must be equally loaded. Even
if CLKOUT is not used, it must have a capacitive load equal
to that on other outputs, for obtaining zero-input-output
delay.
