GENERAL DESCRIPTION
The ADuM41501 is a 6-channel, SPIsolator™ digital isolator
optimized for isolated serial peripheral interfaces (SPIs). Based
on the Analog Devices, Inc., iCoupler® chip scale transformer
technology, the low propagation delay in the CLK, MO/SI,
MI/SO, and SS SPI bus signals supports SPI clock rates of up to
17 MHz. These channels operate with 13 ns propagation delay
and 1 ns jitter to optimize timing for SPI.
The ADuM4150 isolator also provides two additional independent
low data rate isolation channels, one channel in each direction.
Data in the slow channels is sampled and serialized for a 250 kbps
data rate with 2.5 µs of jitter.
The ADuM4150 supports a delay clock output on the master
side of the device. This output can be used with an additional
clocked port on the master to support 40 MHz clock performance.
See the Delay Clock section for more information.
