DESCRIPTION:
The IDT23S05 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 IDT23S05 is an 8-pin version of the IDT23S09. IDT23S05 accepts
one reference input, and drives out five low skew clocks. The -1H version
of this device operates up to 133MHz 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 IDT23S05 enters power down.
In this mode, the device will draw less than 12µA for Commercial Tempera-
ture range 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 IDT23S05 is characterized for both Industrial and Commercial
operation.
