The ADATE304 is a complete, single-chip solution that performs the pin electronic functions of the driver, the comparator, and the active load (DCL), per pin PMU, and dc levels for ATE applications. The device also contains an HVOUT driver with a VHH buffer capable of generating up to 13.5 V.
The driver features three active states: data high mode, data low mode, and term mode, as well as an inhibit state. The inhibit state, in conjunction with the integrated dynamic clamp, facilitates the implementation of a high speed active termination. The ADATE304 supports two output voltage ranges: −2.0 V to +6.0 V and −1.25 V to +6.75 V by adjusting the positive and negative supply voltages.
Each channel of the ADATE304 features a high speed window comparator per pin for functional testing, as well as a per pin PMU with FV, or FI and MV, or MI functions. All necessary dc levels for DCL functions are generated by on-chip 14-bit DACs. The per pin PMU features an on-chip 16-bit DAC for high accuracy and contains integrated range resistors to minimize external component counts.
The ADATE304 uses a serial bus to program all functional blocks and has an on-board temperature sensor for monitoring the device temperature.

Evaluation Kits (1)
The EVAL-ADATE304BBCZ is a full featured evaluation board designed to allow the user to simply evaluate all features of the ADATE304 dual integrated driver, comparator, and active load (DCL) and four-quadrant per pin parametric measurement unit (PPMU). The EVAL-ADATE304BBCZ features breakout connections through the SMA terminals for all the signal inputs and outputs. The differential pairs are provided with 50 Ω controlled impedance traces with equal lengths.
The EVAL-ADATE304BBCZ only requires two power supplies, +21 V and −10 V. All other voltages required by the device are created by the on-board regulators. The EVAL-ADATE304BBCZ SPI communications are provided by an on-board USB UART chip. SPI jumper connectors allow the user to bypass the UART and connect their own SPI signals for evaluation. The default setup is for control through the USB port. Communication with the ADATE304 evaluation board software is through the USB, and the light emitting diode (LED) indicators on the EVAL-ADATE304BBCZ provide displays for the read and write data.
The ADATE304 data sheet provides full details on all the functionalities of the ADATE304 device, as well as the information on each of the registers within the ADATE304, and must be consulted when using the EVAL-ADATE304BBCZ.
