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.

ACTIVE LOAD  
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.

*ONLY 1 (ONE) THERM PER DEVICE  
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.  
,
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 kresistor connected from 10 V to  
the THERM (IOUT) pin. A voltage drop across the resistor will  
be developed that equals 10 kϫ 1 µA/°K = 10 mV/°K = 2.98 V  
at room temperature.  
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
