Edge-based and on-off-keying (OOK) are common communication architectures used in digital isolators. The choice between the two involves tradeoffs, mostly in data rates versus power consumption. Depending on the implementation, there can also be tradeoffs related to noise and transient response and common mode transient immunity (CMTI). This FAQ reviews how edge-based and OOK architecture […]

MOSFET package design improves safety in high-voltage circuits
Littelfuse, Inc. announced the launch of CPC3981Z, an 800 V, 100 mA, 45 Ohm, Small Power N-Channel Depletion Mode MOSFET. Compared to a standard SOT-223 package, this new product’s SOT-223-2L package features a removed middle pin. That increases the drain-gate pin spacing from 1.386 millimeters to more than 4 millimeters. The extended creepage distance is beneficial in […]
How many PCIe card sizes exist today, and where are they used?
There are five standard sizes for PCIe cards and two sizes of mini PCIe. In addition, some larger PCIe slots can accommodate more than one card using a process called bifurcation. This FAQ looks at the five standard sizes and common uses for them. Then turns to mini PCIe and its applications and closes with […]
