简 介:November 2006 rev 1.5 3.3V ‘SpreadTrak’ 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. out five low-skew clocks.
ASM5P23S05A ASM5P23S09A
The -1H version of the ASM5P23SXXA operates at up to 133MHz 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 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 350 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. Th……
