IDT23S05T
DESCRIPTION:
The IDT23S05T 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 IDT23S05T is an 8-pin version of the IDT23S09T. IDT23S05T
accepts one reference input, and drives out five 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 IDT23S05T enters power down. In this mode, the
device will draw less than 12µA for Commercial Temperature Range and
and less than 25µA for Industrial temperature range, the outputs are tri-
stated, and the PLL is not running, resulting in a significant reduction of
power. The IDT23S05T is characterized for both Industrial and Commer-
cial operation.
