The output driving the FBK pin will be driving a total load of 7pF plus any additional load that it drives. The relative loading of this output (with respect to the remaining outputs) can adjust the input output delay. This is shown in the above graph. 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 differences between the feedback output and remaining outputs. For zero output-output skew, be sure to load outputs equally. 3.3V Zero Delay Buffer Notice: The information in this document is subject to change without notice. 3 of 18 ASM5P2308A September 2005 rev 1.4 Pin Configuration REF 1 16 FBK CLKA1 2 15 CLKA4 CLKA2 3 14 CLKA3 VDD 4 13 VDD ASM5P2308A CLKB1 6 12 GND 11 CLKB4 CLKB2 7 10 CLKB3 GND 5 S2 9 8 S1 Pin Description for ASM5P2308A Pin # Pin Name 1 REF3 Description 2 CLKA14 Buffered clock output, bank A 3 CLKA24 Buffered clock output, bank A Input reference frequency, 5V tolerant input 4 VDD 3.3V supply 5 GND Ground 6 CLKB14 Buffered clock output, bank B 7 CLKB24 Buffered clock output, bank B 5 8 S2 9 S1 5 Select input, bit 2 Select input, bit 1 10 4 CLKB3 Buffered clock output, bank B 11 CLKB44 Buffered clock output, bank B 12 GND 13 VDD Ground 3.3V supply 14 4 CLKA3 Buffered clock output, bank A 15 CLKA44 Buffered clock output, bank A 16 FBK PLL feedback input Notes: 3.
