Edge672

500 MHz Pin Electronics

Window Comparator and Load

EDGE HIGH-PERFORMANCE PRODUCTS

Description

The Edge672 is a monolithic ATE pin electronics

comparator and load solution manufactured in a high-

performance complementary bipolar process. In

automatic test equipment, the Edge672 incorporates a

dynamic load and window comparator suitable for very

fast, bidirectional channels in Memory, VLSI, and Mixed-

Signal test systems.

The three-statable load is capable of sourcing and sinking

35 mA over an 11V common mode range. Source and

sink currents are independently programmable. The load

is configurable to support a clamping function, a

termination function, plus any custom load

configurations.

Functional Block Diagram

The comparator is capable of tracking very fast edges

and passing sub-ns pulses over a 11V common mode

range while maintaining excellent timing accuracy. The

differential digital outputs are adjustable to

accommodate ECL levels, PECL levels, or custom levels

to interface directly with a CMOS ASIC.

The inclusion of a high performance load and comparator

in a 32 pin TQFP (7 mm X 7 mm) package offers a

highly integrated solution traditionally implemented with

multiple integrated circuits or discrete components.
