Edge728
Very High-Speed Dual- and
Quad-Channel ECL Delay Lines
HIGH-PERFORMANCE PRODUCTS – ATE
Description
The Edge728 is a quad delay and deskew element.
Manufactured in a high performance bipolar process, it is
designed primarily for channel deskew applications in
Memory Test Equipment.
The part offers a full scale delay range of
8.0 ns with
independent
±
750 ps adjustment of the falling edge.
The Edge728 has a drive mode, where one input signal
is routed to all of the outputs. This mode is particularly
useful in a fanout application.
The delay value (and resolution) is controlled via an external
voltage DAC.
This deskew element is designed specifically to be
monotonic and stable while delaying a very narrow pulse
over a wide delay range.
The Edge728 is a pin and functionally compatible upgrade
to the Edge628 with the following differences:
• greater net usable delay range
• greater net usable falling edge
adjustment range
• only one external bias resistor required
• only one external compensation capacitor required

Features
• Pin and Functionally Compatible with the Edge 628
and Edge624 in Modes 0 and 2
• Independent Delay Adjustments for Positive and
Negative Transitions
• Fanout Mode for One Input Distributed to All
Channels
• 44-pin MQFP Package with Internal Heat Spreader,
44-pin PLCC with Internal Heat Spreader, or
