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 ca...
