ASM5P23S08A September 2005 rev 1.4 3.3V ‘SpreadTrak’ Zero Delay Buffer General Features The ASM5P23S08A has two banks of four outputs each, • which can be controlled by the select inputs as shown in Zero input - output propagation delay, adjustable by capacitive load on FBK input. • Multiple configurations - Refer “ASM5P23S08A Configurations” Table. • Input frequency range: 15MHz to 133MHz • Multiple low-skew outputs. o Output-output skew less than 200pS. o Device-device skew less than 700pS. o Two banks of four outputs, three-stateable by two • Less than 200pS Cycle-to-cycle jitter select inputs. (-1, -1H, -2, -3, -4, -5H). • Available in 16 pin SOIC and TSSOP Packages. • 3.3V operation. • Advanced 0.35µ CMOS technology. • Industrial temperature available. • ‘SpreadTrak’. allows the input clock to be directly applied to the outputs for chip and system testing purposes. Multiple ASM5P23S08A 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. The ASM5P23S08A configurations (Refer is available in “ASM5P23S08A five different Configurations Table). The ASM5P23S08A-1 is the base part, where the output frequencies equal the reference if there is no counter in the feedback path. The ASM5P23S08A-1H is the high-drive version of the -1 and the rise and fall times on this device are faster. The ASM5P23S08A-2 allows the user to obtain 2X and 1X Functional Description ASM5P23S08A is a versatile, 3.3V zero-delay buffer designed to distribute high-speed clocks. It is available in a 16 pin package. The part has an on-chip PLL, which locks to an input clock, presented on the REF pin. The PLL feedback is required to be driven to FBK pin, and can be obtained from one of the outputs. The input-to-output propagation delay is guaranteed to be less than 250pS, and the output-to-output skew is guaranteed to be less than 200pS. the Select Input Decoding Table. The select input also frequencies on each output bank. The exact configuration and output frequencies depends on which output drives the feedback pin. The ASM5P23S08A-3 allows the user to obtain 4X and 2X frequencies on the outputs. The ASM5P23S08A-4 enables the user to obtain 2X clocks on all outputs. Thus, the part is extremely versatile, and can be used in a variety of applications. The ASM5P23S08A-5H is a high-drive version with REF/2 on both banks Alliance Semiconductor 2575 Augustine Drive • Santa Clara, CA • Tel: 408.855.4900 • Fax: 408.855.4999 • www.alsc.com Notice: The information in this document is subject to change without notice.

The output driving the FBK pin will be driving a total For applications requiring zero input-output delay, all outputs including the one providing feedback should be equally loaded. If input-output delay adjustments are required, use the above graph to calculate loading load of 7pF plus any additional load that it drives. The differences between the feedback output and remaining relative loading of this output (with respect to the remaining outputs. For zero output-output skew, make sure to load outputs) can adjust the input output delay. This is shown in outputs equally. the above graph. 3.3V ‘SpreadTrak’ Zero Delay Buffer Notice: The information in this document is subject to change without notice. 3 of 18 ASM5P23S08A September 2005 rev 1.4 Pin Configuration REF 1 16 FBK CLKA1 2 15 CLKA4 CLKA2 3 VDD 4 14 CLKA3 ASM5P23S08A GND 5 13 VDD 12 GND CLKB1 6 11 CLKB4 CLKB2 7 10 CLKB3 S2 8 9 S1 Pin Description for ASM5P23S08A Pin # Pin Name Description 1 REF3 2 CLKA14 Buffered clock output, bank A 3 CLKA24 Buffered clock output, bank A 4 VDD 3.3V supply 5 GND Ground 6 CLKB14 Buffered clock output, bank B 7 CLKB24 Buffered clock output, bank B 8 S25 Select input, bit 2 9 S15 Select input, bit 1 10 CLKB34 Buffered clock output, bank B 11 CLKB44 Buffered clock output, bank B 12 GND Ground 13 VDD 3.3V supply 14 CLKA34 Buffered clock output, bank A 15 CLKA44 Buffered clock output, bank A 16 FBK Input reference frequency, 5V tolerant input PLL feedback input Notes: 3.
