DESCRIPTION:
designed to address high-speed clock distribution applications. The zero
delay is achieved by aligning the phase between the incoming clock and
the output clock, operable within the range of 10 to 133MHz.
accepts one reference input, and drives two banks of four low skew clocks.
The -1H version of this device operates at up to 133MHz frequency and
has 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
IDT2309B enters power down, and the outputs are tri-stated. In this mode,
the device will draw less than 25μA.

The IDT2309B is a 16-pin version of the IDT2305B. The IDT2309B
The IDT2309B is a high-speed phase-lock loop (PLL) clock buffer,
The IDT2309B is characterized for both Industrial and Commercial

... IDT2309B 3.3V ZERO DELAY CLOCK BUFFER ZERO DELAY AND SKEW CONTROL All outputs should be uniformly loaded in order to achieve Zero I/O Delay. Since the CLKOUT pin is the internal feedback for the PLL, its relative loading can affect and adjust the input/output delay.
