Edge728  
Very High-Speed Dual- and  
Quad-Channel ECL Delay Lines  
HIGH-PERFORMANCE PRODUCTS – ATE  
Features  
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.  
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  
Die Form  
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.  
Functional Block Diagram  
This deskew element is designed specifically to be  
monotonic and stable while delaying a very narrow pulse  
over a wide delay range.

DRVMODE  
The Edge728 is a pin and functionally compatible upgrade  
to the Edge628 with the following differences:  
• greater net usable delay range
