GENERAL DESCRIPTION
The ADATE320 is a complete, single-chip 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 digital-to-analog
converters (DACs) with on-chip calibration registers provide all
the necessary dc levels for operation of the device.
The driver features three active modes: high, low, and terminate, as
well as a high impedance inhibit state. The inhibit state, in
conjunction with the integrated dynamic 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 +4.5 V to accommodate a standard range
of ATE and instrumentation applications.
The ADATE320 can be used as a dual, single-ended pin
electronics channel or as a single differential channel. In
addition to per channel high speed window comparators, the
ADATE320 provides a programmable threshold differential
comparator for differential ATE applications.
All dc levels for DCL and PPMU functions are generated by
dedicated, on-chip, 16-bit DACs. To facilitate the programming
of accurate levels, the ADATE320 includes an integrated
calibration function to correct for the gain and offset errors of
each functional block. Correction coefficients can be stored on
chip, and any values written to the DACs adjust automatically
using the appropriate correction factors.
The A
DATE320 uses a serial programmable interface (SPI) bus
to program all functional blocks, DACs, and on-chip calibration
constants. It also has an on-chip temperature sensor and overvolt-
age/undervoltage fault clamps that monitor and report the
device temperature and any output pin or transient PPMU
voltage faults that may occur during operation.
The ADATE320 is available in two options. The standard option
has high speed comparator outputs with 250 mV output swing.
The ADATE320-1 has 400 mV output swing. See the Ordering
Guide for more information.
