3.3V ZERO DELAY

CLOCK BUFFER

FEATURES:

•

IDT2305B

Phase-Lock Loop Clock Distribution

10MHz to 133MHz operating frequency

Distributes one clock input to one bank of five outputs

Zero Input-Output Delay

Low jitter <175 ps cycle-to-cycle

50ps typical cycle-to-cycle jitter (15pF, 66MHz)

IDT2305B-1 for Standard Drive

IDT2305B-1H for High Drive

No external RC network required

Operates at 3.3V V

Power down mode

Available in SOIC and TSSOP packages

DESCRIPTION:

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 25

μA,

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.
