PRODUCT DESCRIPTION
The AD53522 is a complete, high speed, single-chip solution
that performs the pin electronics functions of driver, comparator,
and active load (DCL) for ATE applications. In addition, the
driver contains a dynamic clamp function and the active load
contains an integrated Schottky diode bridge.
The driver is a proprietary design that features three active states:
Data High mode, Data Low mode, and Term mode, as well as
an Inhibit State. In conjunction with the integrated dynamic
clamp, this facilitates the implementation of a high speed active
termination. The output voltage range is –0.5 V to +6.5 V to
accommodate a wide variety of test devices.
The dual comparator, with an input range equal to the driver
output range, features PECL compatible outputs. Signal tracking
capability is in the range of 3 V/ns.
The active load can be set for up to 40 mA load current. IOH, IOL,
and the buffered VCOM are independently adjustable. On-board
Schottky diodes provide high speed switching and low capacitance.
Also included is an on-board temperature sensor that gives an
indication of the silicon surface temperature of the DCL. This
information can be used to measure ␪JC and ␪JA or flag an alarm
if proper cooling is lost. Output from the sensor is a current sink

that is proportional to absolute temperature. The gain is trimmed
to a nominal value of 1.0 µA/K. As an example, the output current
can be sensed by using a 10 kΩ resistor connected from 10 V to
the THERM (IOUT) pin. A voltage drop across the resistor will
be developed that equals 10 kΩ ⫻ 1 µA/°K = 10 mV/°K = 2.98 V
at room temperature.

All temperature coefficients are measured at TJ = 75°C to 95°C. In test figures, voltmeter loading is 1 MΩ or greater, scope probe loading is 100 kΩ in parallel with 0.6 pF.
2
Typical values are not tested or guaranteed. Nominal values are generated from design or simulation analyses and/or limited bench evaluations and are not tested or guaranteed.
3
Spec Perf: N = Nominal, O = Operating Condition, T = Typical, P = Production, Max/Min.
4
VTERM linearity over the following condition: VL – 6 V < VTERM < VH + 6 V.
5
All ac input values are referred to the source end of transmission line input.
6
All ac tests are performed with driver in VTERM mode except where noted.
7
Rise time is calculated SQRT((comp out Tr) 2 – (comp in Tr) 2).

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Absolute maximum limits apply
individually, not in combination. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
2
Output short circuit protection is guaranteed as long as proper heat sinking is
employed to ensure compliance with the operating temperature limits.
3
To ensure lead coplanarity (± 0.002 inches) and solderability, handling with bare
hands should be avoided and the device should be stored in environments at 24 °C
± 5°C (75°F ± 10°F) with relative humidity not to exceed 65%.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD53522 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
