SUPPORTED SPIsolator MODELS
ADuM3154ARSZ
ADuM3154BRSZ
GENERAL DESCRIPTION
The E VA L-ADuM3154Z supports the ADuM3154ARSZ and
ADuM3154BRSZ, which are, 4-channel SPIsolator isolators
optimized for use in SPI applications. They include two low
speed address pins to rout the slave select to one of four
destinations. 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.
