GENERAL DESCRIPTION
The ADATE302-02 is a complete, single-chip solution that
performs the pin electronic functions of the driver, the compa-
rator, 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 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.
