LOW SKEW, 1-TO-12 LVCMOS/LVTTL

FANOUT BUFFER

ICS8312

Features

•

Twelve LVCMOS/LVTTL outputs

CLK input supports the following input types: LVCMOS, LVTTL

Maximum output frequency: 250MHz

Output skew: 150ps (maximum)

Supply modes:

Core/Output

3.3V/3.3V

3.3V/2.5V

3.3V/1.8V

2.5V/2.5V

2.5V/1.8V

1.8V/1.8V

0°C to 85°C ambient operating temperature

Available in both standard (RoHS 5) and lead-free (RoHS 6)

packages

General Description

The ICS8312 is a low skew, 1-to-12 LVCMOS/

LVTTL Fanout Buffer and a member of the

HiPerClockS™

HiPerClockS™ family of High Performance Clock

Solutions from IDT. The ICS8312 single-ended clock

input accepts LVCMOS or LVTTL input levels. The

low impedance LVCMOS outputs are designed to drive 50Ω series

or parallel terminated transmission lines. The effective fanout can

be increased from 12 to 24 by utilizing the ability of the outputs to

drive two series terminated lines.

ICS

The ICS8312 is characterized at full 3.3V, 2.5V, and 1.8V, mixed

3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply

modes. Guaranteed output and part-to-part skew characteristics

along with the 1.8V output capabilities makes the ICS8312 ideal

for high performance, single ended applications that also require a

limited output voltage.
