EDGE728

m o c . HIGH-PERFORMANCE PRODUCTS – ATE U 4 t Description e e h The Edge728 is a quad delay and deskew element. S a Manufactured in a high performance bipolar process, it is designed primarily at for channel deskew applications in Memory Test .DEquipment. w The w part offers a full scale delay range of ≥ 8.0 ns with independent ± 750 ps adjustment of the falling edge. w 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 Edge728 Very High-Speed Dual- and Quad-Channel ECL Delay Lines 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 Die Form Functional Block Diagram Applications Automatic Test Equipment Memory Tester Drive On Channel Deskew...
