DESCRIPTION:
The IDT23S05E 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 200MHz.
The IDT23S05E is an 8-pin version of the IDT23S09E. IDT23S05E
accepts one reference input, and drives out five low skew clocks. The -1H
version of this device operates up to 200MHz frequency and has a 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 IDT23S05E enters
power down. In this mode, the device will draw less than 12µA for
Commercial Temperature range and less than 25µA for Industrial tempera-
ture range, the outputs are tri-stated, and the PLL is not running, resulting
in a significant reduction of power.
The IDT23S05E is characterized for both Industrial and Commercial
operation.
