The ADATE334 is a complete dual-channel automatic test equip-
ment (ATE) solution that performs the pin electronics functions of a
driver, comparator, and active load (DCL), and a four-quadrant per
pin parametric measurement unit (PPMU). Dedicated, 16-bit DACs
with on-chip calibration registers provide all necessary dc levels for
device operation.
The high voltage driver features three active states: high mode,
low mode, and terminate mode, as well as a high impedance
inhibit state. The inhibit state, in conjunction with the integrated dy-
namic clamps, facilitates significant attenuation of transmission line
reflections when the driver is not actively terminating the line. The
open-circuit drive capability is −1.5 V to +7.0 V to accommodate a
wide range of ATE and instrumentation applications.
The low voltage driver, working in conjunction with the high voltage
driver, can provide 25 mV p-p to 600 mV p-p signals at up to 4.6
Gbps in a 50 Ω environment.

The ADATE334 can be used either as a dual, single-ended pin
electronics channel or as a single differential channel. In addition
to per-channel, high speed window comparators, the ADATE334
provides a programmable threshold differential comparator for dif-
ferential ATE applications and a zero-crossing comparator.
All dc levels for DCL and PPMU functions are generated by dedi-
cated, on-chip, 16-bit DACs. To facilitate accurate level program-
ming, the ADATE334 includes an integrated calibration function that
corrects gain and offset errors of each functional block. Correction
coefficients can be stored on-chip, and any values written to the
DACs automatically adjust using the appropriate correction factors.
The ADATE334 uses a serial programmable interface (SPI) bus
to program all functional blocks, DACs, and on-chip calibration
constants. The ADATE334 has an on-chip temperature sensor to
monitor temperature and overvoltage and undervoltage alarms that
monitor and report any output pin or transient PPMU voltage faults
that can occur during operation. The ADATE334 also provides a per
channel, open-drain relay driver.
