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
