DESCRIPTION:
• Phase-Lock Loop Clock Distribution
• 10MHz to 133MHz operating frequency
• Distributes one clock input to one bank of five and one bank of
four outputs
The IDT23S09 is a high-speed phase-lock loop (PLL) clock buffer,
designedtoaddresshigh-speedclockdistributionapplications. Thezero
delay is achieved by aligning the phase between the incoming clock and
the output clock, operable within the range of 10 to 133MHz.
• Separate output enable for each output bank
• Output Skew < 250ps
• Low jitter <200 ps cycle-to-cycle
• IDT23S09-1 for Standard Drive
• IDT23S09-1H for High Drive
The IDT23S09 is a 16-pin version of the IDT23S05. The IDT23S09
acceptsonereferenceinput,anddrivestwobanksoffourlowskewclocks.
The-1Hversionofthisdeviceoperatesupto133MHzfrequencyandhas
higher drive than the -1 device. All parts have on-chip PLLs which lock
to an input clock on the REF pin. The PLL feedback is on-chip and is
obtained from the CLKOUT pad. In the absence of an input clock, the

• No external RC network required
• Operates at 3.3V VDD
• Spread spectrum compatible
• Available in SOIC and TSSOP packages
