5千伏6通道数字隔离器SPI的时钟延迟adum4150数据表

　　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.
