Overview

IDT2305 3.
3V ZERO DELAY CLOCK BUFFER COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGES 3.
3V ZERO DELAY CLOCK BUFFER IDT2305 FEATURES: • Phase-Lock Loop Clock Distribution • 10MHz to 133MHz operating frequency • Distributes one clock input to one bank of five outputs • Zero Input-Output Delay • Output Skew < 250ps • 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 DESCRIPTION: 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.
The IDT2305 is an 8-pin version of the IDT2309.
IDT2305 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 IDT2305 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 IDT2305 is characterized for both Industrial and Commercial operation.
