IDT™ / ICS™

3.3 VOLT ZERO DELAY LOW SKEW BUFFER 1

ICS2309 REV F 041906

Description

The ICS2309 is a low phase noise, high-speed PLL

based, low-skew zero delay buffer. Based on ICS’

proprietary low jitter Phase Locked Loop (PLL)

techniques, the device provides nine low skew outputs

at speeds up to 133 MHz at 3.3 V. The outputs can be

generated from the PLL (for zero delay), or directly from

the input (for testing), and can be set to tri-state mode

or to stop at a low level. The PLL feedback is on-chip

and is obtained from the CLKOUT pad.

The ICS2309 is available in two different versions. The

ICS2309-1 is the base part. The ICS2309-1H is a high

drive version with faster rise and fall times.

Features

•Clock outputs from 10 to 133 MHz

•Zero input-output delay

•Nine low skew (<250 ps) outputs

•Device-to-device skew <700 ps

•Full CMOS outputs with 12 mA output drive

capability at TTL levels

•5 V tolerant CLKIN

•Tri-state mode for board-level testing

•Advanced, low power, sub-micron CMOS process

•Operating voltage of 3.3 V

•Industrial temperature range available

•Packaged in 16-pin SOIC and TSSOP (-1H version

only)

•RoHS 5 (green) or RoHS 6 (green and lead free)

complaint packaging

External Components

The ICS2309 requires a minimum number of external components for proper operation. Decoupling

capacitors of 0.01 mF should be connected between VDD and GND on pins 4 and 5, and VDD and GND

on pins 13 and 12, as close to the device as possible. A series termination resistor of 33Ω may be used to

each clock output pin to reduce reflections.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS2309. These ratings,

which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of

the device at these or any other conditions above those indicated in the operational sections of the

specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can

affect product reliability. Electrical parameters are guaranteed only over the recommended operating

temperature range.
