Skyworks Solutions Inc. Si88x4x Quad Digital Isolators

Skyworks Solutions Inc. Si88x4x Quad Digital Isolators combine proven digital isolator technology with an on-chip isolated DC-DC converter. This feature provides regulated output voltages of 3.3 or 5.0V (or >5V with external components) at peak output power levels of up to 2W. These devices offer up to four digital channels. The DC-DC converter has a user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shutdown option, and loop compensation. The ultra-low-power digital isolation channels offer substantial data rates, propagation delay, size, and reliability advantages over legacy isolation technologies. Data rates up to 100Mbps are supported, and all of these Skyworks devices achieve propagation delays of only 23ns.
