CLOCK SYNCHRONIZER AND MULTIPLIER CLOCK SYNTHESIZER IDT™ CLOCK SYNCHRONIZER AND MULTIPLIER 2 IDT9170B REV B 052609 Pin Assignment Pin Descriptions Using the IDT9170B The IDT9170B has the following characteristics: 1. Risin g edges at IN and FBIN are lined up. Falling edges ar e not synchronized. 2. T he relationship between the frequencies at FBIN and IN wit h CLK1 feedback is shown in Table 1 below. Functionality (Table 1) 3. The frequency of CLK2 is half the CLK1 frequency. 4. The CLK1 frequency ranges are: Eliminate High Speed Clock Routing Problems The IDT9170B makes it possible to route lower speed clocks over long distances on the PC board and to place an IDT9170B next to the device requiring a higher speed clock. The multiplied output can then be used to produce a phase locked, higher speed output clock. Compensate for Propagation Delays Including an IDT9170B in a timing loop allows the use of PALs, gate arrays, etc., with loose timing specifications. The IDT9170B compensates for the delay through the PAL and synchronizes the output to the input reference clock.

CLOCK SYNCHRONIZER AND MULTIPLIER CLOCK SYNTHESIZER IDT™ CLOCK SYNCHRONIZER AND MULTIPLIER 3 IDT9170B REV B 052609 Operating Frequency Range The IDT9170B is offered in versions optimized for operation in two frequency ranges. The -01 covers high frequencies, 20 to 100 MHz.* The -02 operates from 5 to 25 MHz.* The IDT9170B can be supplied with custom multiplication factors and operating ranges. Consult IDT for details.

3.3 V VDD Operation

The IDT9170B does operate at both 5.0 V and 3.3 V system conditions. Please note the Electrical Characteristic specifications at 3.3 V include a limited output frequency (66.6 MHz max.) and a wider skew of FBIN to CLK1. For 3.3 (3.0 V min.), the skew is widened to -8 ns to 0 ns and should be accounted for in system design. *At 3.3 V, the maximum CLK1 frequency is 66.7 MHz for - 01 4 and 16.7 MHz for -02.
