General Features

Functional Description

ASM5P23S09A is a versatile, 3.3V zero-delay buffer

designed to distribute high-speed clocks with Spread

Spectrum capability. It is available in a 16-pin package. The

ASM5P23S05A

ASM5P23S09A. It accepts one reference input and drives

out five low-skew clocks.

The -1H version of the ASM5P23SXXA operates at up to

10 MHz to 133- MHz operating range, compatible

with CPU and PCI bus frequencies.

Zero input - output propagation delay.

Multiple low-skew outputs.



Less than 200 ps cycle-to-cycle jitter is compatible

with Pentium

refer Select Input Decoding Table).

Available in 16-pin, 150-mil SOIC, 4.4 mm

Output-output skew less than 250 ps.

Device-device skew less than 700 ps.

One input drives 9 outputs, grouped as 4 + 4

the

133- MHz 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 ASM5P23S09A has two banks of four outputs each,

which can be controlled by the Select inputs as shown in

the Select Input Decoding Table. If all the output clocks are

not required, Bank B can be three-stated. The select input

also allows the input clock to be directly applied to the

outputs for chip and system testing purposes.

Multiple ASM5P23S09A and ASM5P23S05A 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 200 ps of cycle-to-cycle jitter.

The input and output propagation delay is guaranteed to be

less than 250 ps, and the output to output skew is

guaranteed to be less than 250ps.

The ASM5P23S09A and the ASM5P23S05A are available

in two different configurations, as shown in the ordering

information table. The ASM5P23SXXA-1 is the base part.

The ASM5P23SXXA-1H is the high drive version of the -1

and its rise and fall times are much faster than -1 part.
