3.3V `SpreadTrak' Zero Delay Buffer
General Features
15 MHz to 133 MHz operating range, compatible with CPU and PCI bus frequencies. Zero input - output propagation delay. Multiple low-skew outputs. Output-output skew less than 250 pS. Device-device skew less than 700 pS. One input drives 9 outputs, grouped as 4+4+1 (ASM5P23S09A). One input drives 5 outputs (ASM5P23S05A). Less than 200 pS cycle-to-cycle jitter is compatible with Pentium based systems. Test Mode to bypass PLL (ASM5P23S09A only, refer Select Input Decoding Table). Available in 16-pin, 150-mil SOIC and 4.4 mm TSSOP packages for ASM5P23S09A and in 8-pin, 150-mil SOIC and 4.4 mm TSSOP packages for ASM5P23S05A. 3.3V operation Advanced 0.35< CMOS technology. `SpreadTrak'.

out five low-skew clocks. The -1H version of the ASM5P23SxxA operates at up to 133 MHz frequency, and has higher drive than the -1 device. 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 700 pS. 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 250 pS. 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 part and its rise and fall times are much faster than -1 part.
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 is the eight-pin version of the ASM5P23S09A. It accepts one reference input and drives

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.
SpreadTrak
Many systems being designed now utilize a technology called Spread Spectrum Frequency Timing Generation. ASM5P23S09A and ASM5P23S05A are designed so as not to filter off the Spread Spectrum feature of the Reference input, assuming it exists. When a zero delay buffer is not designed to pass the Spread Spectrum feature through, the result is a significant amount of tracking skew which may cause problems in the systems requiring synchronization.
