PRODUCT DESCRIPTION
The AD53509 is a single chip that performs the pin electronics functions of driver, comparator and active load in ATE VLSI and memory testers. In addition, a Schottky diode bridge for the active load and a VCOM buffer are included internally. 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. This facilitates the implementation of high speed active termination. The output voltage range is 2 V to +7 V to accommodate a wide variety of test devices. The output leakage is typically less than 250 nA over the entire signal range. The dual comparator, with an input range equal to the driver output range, features built-in latches and ECL-compatible outputs. The outputs are capable of driving 50 signal lines terminated to 2 V. Signal tracking capability is upwards of 5 V/ns. The active load can be set for up to 40 mA load current with less than a 10 µA linearity error through the entire set range. IOH, IOL and the buffered VCOM are independently adjustable. On-board Schottky diodes provide high speed switching and low capacitance. Also included on the chip is an on-board temperature sensor whose purpose is to give an indication of the 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 k resistor connected from 10 V to the THERM (IOUT) pin. A voltage drop across the resistor will be developed that equals: 10K × 1 µA/K = 10 mV/K = 2.98 V at room temperature.
