GENERAL DESCRIPTION
The EVAL-ADuM3151Z supports the parts listed in the
supported models section, which are, 7-channel, data direction
variants of SPIsolator isolators optimized for use in SPI
applications. They include three low speed channels for axillary
functions, which are not timing critical. The evaluation board
provides a JEDEC standard 20-lead SSOP pad layout, support
for signal distribution, loopback, and loads referenced to V
DDx
or
GND
x
, as well as optimal bypass capacitance. Signal sources can
be wired onto the board as well as brought onto the board
through edge-mounted SMA connectors (sold separately) or
terminal blocks for power connections. The board includes 200 mil
header positions for compatibility with Tektronix active probes.
The board follows best printed circuit board (PCB) design practices
for 4-layer boards, including a full power and ground plane on
each side of the isolation barrier. No other EMI or noise mitigation
design features are included on this board. In cases of very high
speed operation or when ultralow emissions are required, refer
to the AN-1109 application note for additional board layout
techniques.
