Overview

  • 3-level driver with high-Z mode and built-in clamps
  • Precision trimmed output resistance
  • Low leakage mode (typically <10 nA)
  • Voltage range: −2.0 V to +6.0 V
  • 1.0 ns minimum pulse width, 1 V terminated
  • Window and differential comparator
  • >1 GHz input equivalent bandwidth
  • ±12 mA maximum current capability

The ADATE302-02 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.

TThe 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 output voltage range is −2.0 V to +6.0 V to accommodate a wide variety of test devices.

The ADATE302-02 can be used as either a dual single-ended drive/receive channel or a single differential drive/receive channel. Each channel of the ADATE302-02 features a high speed window comparator 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 ADATE302-02 uses a serial bus to program all functional blocks and has an on-board temperature sensor for monitoring the device temperature.

Product Details

The EV-ADATE302-02EBZ is a full featured evaluation board designed to allow simple evaluation of all features of the ADATE302-02 dual-integrated driver, comparator, and active load (DCL) and four-quadrant per pin parametric measurement unit (PPMU). The EV-ADATE302-02EBZ features breakout connections through the Subminiature Version A (SMA) terminals for all the signal inputs and outputs. The differential pairs are provided with 50 Ω controlled impedance traces with equal lengths.

The EV-ADATE302-02EBZ 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 EV-ADATE302-02EBZ serial peripheral interface (SPI) communications are provided by an onboard USB universal asynchronous receiver transmitter (UART) chip. SPI jumper connectors allow users to bypass the UART and connect their own SPI signals for evaluation (see Table 1). The default setup is for control through the USB port. Communication with the ADATE302-02 evaluation board software is through the USB, and the light emitting diode (LED) indicators on the EV-ADATE302-02EBZ provide displays for the read and write data.

The ADATE302-02 data sheet provides full details on all the features of the ADATE302-02 device, as well as the information on each of the registers within the ADATE302-02, and must be consulted when using the EV-ADATE302-02EBZ evaluation board.
