GENERAL DESCRIPTION
The EVAL-ADATE320EBZ is a full-featured evaluation board de-
signed to allow the user to simply evaluate all features of the
ADATE320 dual-integrated driver, comparator, and active load
(DCL) with a per pin parametric measurement unit (PPMU). The
EVAL-ADATE320EBZ features breakout connections through the
Subminiature Version A (SMA) terminals for all of the signal inputs
and outputs. The differential pairs are provided with 50 Ω-controlled
impedance traces with equal lengths.
The EVAL-ADATE320EBZ only takes in +12 V and −8 V supplies,
and the on-board regulators provide the required device supplies.
The EVAL-ADATE320EBZ can be controlled through the on-board
connectors or through the USB port of a Windows-based PC using
the ADATE320 Evaluation Board Software, which is available for
download on the EVAL-ADATE320EBZ product page. The default
setup is for control through the USB port. Communication with
the ADATE320 Evaluation Software is through the USB, and the
light emitting diode (LED) indicators on the EVAL-ADATE320EBZ
provide displays for the read and write data.
The ADATE320 data sheet provides full details on the ADATE320,
as well as the information on each of the registers within
the ADATE320, and must be consulted when using the EVAL-
ADATE320EBZ.
