Related Products optimized for isolated serial peripheral interfaces (SPIs). Based Product Description on the Analog Devices, Inc., iCoupler chip scale transformer ADuM3150 3.75 kV, high speed, clock delayed technology, the low propagation delay in the CLK, MO/SI, SPIsolator SS MI/SO, and SPI bus signals supports SPI clock rates of up to ADuM3151/ADuM3152/ 3.75 kV, multichannel SPIsolator 17 MHz. These channels operate with 13 ns propagation delay ADuM3153 and 1 ns jitter to optimize timing for SPI. ADuM3154 3.75 kV, multiple slave SPIsolator ADuM4151/ADuM4152/ 5 kV, multichannel SPIsolator The ADuM4150 isolator also provides two additional independent ADuM4153 low data rate isolation channels, one channel in each direction. ADuM4154 5 kV, multiple slave SPIsolator Data in the slow channels is sampled and serialized for a 250 kbps data rate with 2.5 s 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. 1 Protected by U.S. Patents 5,952,849 6,873,065 6,262,600 and 7,075,329. Other patents are pending. Rev.
