Edge7725

900 MHz Dual Pin Electronics Driver,

Window Comparator, and Load

TEST AND MEASUREMENT PRODUCTS

Features

Description

• Fully Integrated Three-Statable, Tri-Level Driver,

Window Comparator, and Dynamic Active Load

• Wide Choice of Range, Performance vs. Power

• Differential Driver and Comparator Modes

• Programmable Driver Rise, Fall Times

• Programmable Voltage Clamps on Comparator Input

• –2V, +7V Driver, Compare, Load Range

• ±32 mA Programmable Load

The Edge7725 dual channel, monolithic ATE pin electron-

ics solution is manufactured in a high-performance comple-

mentary bipolar process.

The Edge7725 operates greater than 900 MHz/1.8 Gbps.

The power supplies to the Edge7725 are specified over a

wide range to accommodate between –2V, +7V and –0.5V,

+4.2V input, output voltages.

• Comparator Input Tracking to >3V/ns

• Small, 128-Pin MQFP Package

The three-statable Edge7725 tri-level driver is capable of

generating 8V swings over a –2 to +7V range, with a mini-

mum swing of 100 mV. The driver’s third level is used when

the driver acts as a switched termination, and the load is

not being used. The differential driver mode permits the

inverse of DHI driving of Channel 0 to be output on Chan-

nel 1, creating differential outputs having a minimum of

skew. An input power down mode lowers the DOUT leak-

age current.

Applications

• Logic Testers

• Mixed-Signal Test Equipment

• Memory Testers

• Flash Memory Testers

• ASIC Verifiers

The Edge7725 window comparator can span a 9V com-

mon mode range. Programmable voltage clamps at the

input to the comparator provide a means to clamp voltage

overshoots and excessive ringing for unterminated com-

parator input signals. An input power down mode lowers

the VINP input leakage currents.

The Edge7725 differential comparator can compare input

differences of up to 800mV to input levels which are sepa-

rate from those of the window comparators.

The Edge7725 load supports programmable source and

sink currents of ±32 mA over a –2V to +7V range, or it can

be completely disabled. The load may be configured as a

“split load” whereby the load can act as a voltage clamp

as an alternate to the comparator’s clamp. For operating

modes requiring no load, the Edge7725’s load may be

depowered to conserve power.
