Based on the Analog Devices, Inc., iCoupler OB IB BLOCK BLOCK chip scale transformer technology, the low propagation delay in V V 9 12 OC IC SS the CLK, MO/SI, MI/SO, and SPI bus signals supports SPI GND 10 11 GND 2 1 clock rates of up to 17 MHz. These channels operate with 14 ns Figure 2. ADuM3152 Functional Block Diagram propagation delay and 1 ns jitter to optimize timing for SPI. V 1 20 V The ADuM3151/ADuM3152/ADuM3153 isolators also provide DD1 ADuM3153 DD2 three additional independent low data rate isolation channels in GND 2 19 GND 1 2 ENCODE DECODE three different channel direction combinations. Data in the slow MCLK 3 18 SCLK ENCODE DECODE channels is sampled and serialized for a 250 kbps data rate with MO 4 17 SI DECODE ENCODE up to 2.5 s of jitter in the low speed channels.
