A Constant Speed Drive (CSD) is a transmission which converts input from the engine accessory gearbox and generates a constant RPM output to an attached generator through a series of reduction gears.

An Integrated Drive Generator (IDG) is a combination of both the transmission and generator in the same assembly, and converts input RPM from the engine assembly gearbox to generate a constant RPM in the generator.

Both the CSD and IDG are responsible for creating constant frequency electrical energy for electrical systems in an aircraft.
