Fanout Buffer

8312I

Datasheet

General Description

Features

The 8312I is a low skew, 1-to-12 LVCMOS/ LVTTL Fanout Buffer

and a member of the family of High Performance Clock Solutions

from IDT. The 8312I single-ended clock input accepts LVCMOS or

LVTTL input levels. The low impedance LVCMOS outputs are

designed to drive 50 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.

• Twelve LVCMOS/LVTTL outputs

• CLK input supports the following input types: LVCMOS, LVTTL

• Maximum output frequency: 250MHz

• Output skew: 160ps (maximum)

• Supply modes:

Core/Output

3.3V/3.3V

3.3V/2.5V

The 8312I 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 8312I ideal for

high performance, single ended applications that also require a

limited output voltage.

2.5V/2.5V

2.5V/1.8V

1.8V/1.8V

• -40°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) package
