ASM5P2305A, ASM5P2309A 3.3 V Zero Delay Buffer Description ASM5P2309A is a versatile, 3.3 V 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 ASM5P230xA operates at up to 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. The PLL feedback is on−chip and is obtained from the CLKOUT. 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 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 ±350 pS, and the output to output skew is guaranteed to be less than 200 pS. 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 SOIC−8 S SUFFIX CASE 751BD SOIC−16 S SUFFIX CASE 751BG TSSOP−8 T SUFFIX CASE 948AL TSSOP−16 T SUFFIX CASE 948AN the −1 and its rise and fall times are faster than −1 part.

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. 1500 1000 500 0 −500 −1000 −30 −25 −20 −15 −10 −5 0 5 10 15 20 25 30 −1500 Figure 2.
