DESCRIPTION:
The IDT23S09T is a high-speed phase-lock loop (PLL) clock buffer,
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.
The IDT23S09T is a 16-pin version of the IDT23S05T. The IDT23S09T
accepts one reference input, and drives two banks of four low skew clocks.
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 IDT23S09T enters power down, and
the outputs are tri-stated. In this mode, the device will draw less than 12A.
