Description
Edge710
500 MHz Pin Electronics Driver,
Window Comparator, and Load
Features
The Edge710 is a totally monolithic ATE pin electronics
solution manufactured in a high-performance
complementary bipolar process. In Automatic Test
Equipment (ATE) applications, the Edge710 incorporates
a driver, a load, and a window comparator suitable for
very fast bidirectional channels in VLSI, Mixed-Signal, and
Memory test systems.
The three-statable driver is capable of generating 9V swings
over a 12V range. In addition, 13V super voltage may be
obtained under certain operating conditions. Separate
rise and fall edge adjustments support both high speed
and low speed applications, and allow for superior rise
and fall time matching. An input power down mode allows
extremely low leakage current in HiZ.
• Fully Integrated Three-Statable Driver, Window
Comparator, and Dynamic Active Load
• 12V Driver, Load, Compare Range
• 13V Super Voltage Capable
± 35 mA Programmable Load
• Comparator Input Tracking >6V/ns
• Leakage (L+D+C) < 1 µA (normal mode)
• Leakage (L+D+C) < 25 nA (IPD mode)
• Small footprint (52 pin MQFP)
Functional Block Diagram
The load supports programmable source and sink currents
of ± 35 mA over a 12V range, or it can be completely
disabled. The source current, sink current, and
commutating voltage are all independently set. In addition,
the load is configurable and may be used as a
programmable voltage clamp.
The window comparator spans a 12V common mode
range, tracks input signals with edge rates greater than 6
V/ns, and passes sub-ns pulses. An input power down
mode allows for extremely low leakage measurements.
The inclusion of all pin electronics building blocks into a
52 lead MQFP (10 mm body w/ internal heat spreader)
offers a highly integrated solution that is traditionally
implemented with multiple integrated circuits or discretes.

Circuit Description (continued)
Source and Sink Current Levels
Commutating Voltage Compensation
The amount of current that the diode bridge can source
and sink is adjustable from 0 mA to 35 mA. The source
and sink levels are separate and independent.
ISC_IN and ISK_IN are current controlled inputs whose
voltage level is held very close to ground (<100 mV
variation) over the entire legal current input range.
The VCM_CAP pin is an op amp compensation node that
requires a fixed .01 µF chip capacitor (with good high
frequency characteristics) to ground. This capacitor is
used to compensate an internal node on the on-chip buffer
for the commutating voltage input.
Split Load
There is a nominal gain of 20 between the ISC_IN current
and the bridge source current.
ISOURCE = 20 * ISC_IN
There is a nominal gain of –20 between the ISK_IN current
and the bridge sink current.
ISINK = –20 * ISK_IN
The VCM_OUT_A is the actual commutating voltage
generated by the on-chip buffer. VCM_OUT_A is also
connected to the upper half of the diode bridge, and is
responsible for sinking the programmed source current
when the load is sinking current from the DUT.
VCM_OUT_B is connected to the lower half of the diode
bridge, and is responsible for providing the sink current
when the load is sourcing current to the DUT.
Because the inversion creates a 180˚ phase shift between
ISK_IN and ISINK, there is a tendency toward instability.
A minimum of 500 W of external series resistance should
be used between an external voltage or current source
and the ISC_IN and ISK_IN pins to ensure stability. Stray
capacitance at the ISK_IN pin should be kept to a
minimum. PCB layout should minimize coupling between
ISK_IN and LOAD.
Caution: The ISKIN and ISCIN inputs are designed for
positive current between 0 mA and 1.75 mA flowing into
the part. Care should be taken to insure that current is
never required to flow out of the part on these two nodes.
VCM_OUT_B does NOT have an on-chip buffer. To
configure the load as a standard active diode bridge,
connect VCM_OUT_A and VCM_OUT_B together off-chip.
Or, to configure the load as a split load, an external buffer
must be used for VCM_OUT_B.
External Bridge Connections
Access to the top and bottom of the diode bridge is granted
through a 1 KW resistor. Pins BRIDGE_SC and BRIDGE_SK
allow external current sources to be used instead of the
internal I_SOURCE and I_SINK sources. These external
pins are useful when extremely accurate source and sink
currents are required for low current operation.
