GENERAL DESCRIPTION
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 appli-
cations. 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, facili-
tates 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.
