The IDT2305B 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 IDT2305B is an 8-pin version of the IDT2309B. IDT2305B 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 IDT2305B enters power
down. In this mode, the device will draw less than 25μA, the outputs are
tri-stated, and the PLL is not running, resulting in a significant reduction of
power.
The IDT2305B is characterized for both Industrial and Commercial
operation.
