GENERAL DESCRIPTION
The ADATE318 is a complete, single-chip ATE solution that
performs the pin electronics functions of driver, comparator,
and active load (DCL), four quadrant, per pin, parametric
measurement unit (PPMU). It has VHH drive capability per
chip to support flash memory testing applications and integ-
rated 16-bit DACs with an on-chip calibration engine to
provide all necessary dc levels for operation of the part.
The driver features three active states: data high, data low, and
terminate mode, as well as a high impedance inhibit state. The
inhibit state, in conjunction with the integrated dynamic
clamps, facilitates the implementation of a high speed active
termination. The output voltage capability is −1.5 V to +6.5 V
to accommodate a wide range of ATE and instrumentation
applications.
The ADATE318 can be used as a dual, single-ended drive/
receive channel or as a single differential drive/receive channel.
Each channel of the ADATE318 features a high speed window
comparator as well as a programmable threshold differential
comparator for differential ATE applications. A four quadrant
PPMU is also provided per channel.
All dc levels for DCL and PPMU functions are generated by 24
on-chip 16-bit DACs. To facilitate accurate levels programming,
the ADATE318 contains an integrated calibration function to
correct gain and offset errors for each functional block.
Correction coefficients can be stored on chip, and any values
written to the DACs are automatically adjusted using the
appropriate correction factors.
The ADATE318 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
over/undervoltage fault clamps for monitoring and reporting
the device temperature and any output pin or PPMU voltage
faults that may occur during operation.
