3.3V ZERO DELAY

CLOCK BUFFER

FEATURES:

DESCRIPTION:

• Phase-Lock Loop Clock Distribution

• 10MHz to 133MHz operating frequency

• Distributes one clock input to one bank of five outputs

• Zero Input-Output Delay

The IDT2305 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.

• Output Skew < 250ps

The IDT2305 is an 8-pin version of the IDT2309. IDT2305 accepts one

referenceinput,anddrivesoutfivelowskewclocks.The-1Hversionofthis

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 IDT2305 enters power down. In

• Low jitter <200 ps cycle-to-cycle

• IDT2305-1 for Standard Drive

• IDT2305-1H for High Drive

• No external RC network required

• Operates at 3.3V VDD

• Power down mode

• Available in SOIC/TSSOP packages

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 IDT2305 is characterized for both Industrial and Commercial

operation.
