Edge142

Per Pin timing Deskew w 4x2

Cross Point Switch

EDGE HIGH-PERFORMANCE PRODUCTS

Features

Description

• Very Narrow (<1 ns) Pulse Width Capability

• Fmax > 850 MHz

• Independent Delay Adjustments for Positive and

Negative Transitions

The Edge142 is a 4 X 2 cross point switch with output

edge deskew capability. Manufactured in a high

performance bipolar process, it is designed primarily for

channel deskew applications in VLSI and Mixed-Signal

test equipment.

• Delay Range of 1.5 ns

• Trailing Edge Adjust Range of 300 ps

• Small Footprint: 52-pin MQFP Package

(10 X 10 mm) with Internal Heat Spreader or

Die Form

Any of the four input signals may be selected as the

source for either output. The 142 performs test head

multiplexing, adjacent channel multiplexing, and signal

buffering for both the drive and receive signals, in addition

to timing deskew.

The delay value (and resolution) is controlled via an

external voltage DAC. The delay element is designed

specifically to be monotonic and very stable while

delaying a very narrow pulse over a limited delay range.

Applications

The part offers separate delays for rising vs. falling edges.

The rising edge delay range is 1.5 ns and the falling

edge adjustment range is 300 ps.

• Automatic Test Equipment

– Per pin deskew in VLSI, Mixed-Signal, and Memory

Testers

– Clock Distribution with timing adjustment

The Edge142 is also well suited for 1:2 or 1:4 signal

fanout applications that require:

- multiple signal sources

- output enable / disable

- timing deskew on the output

signals.
