It can be used to generate up to four configurable PWM outputs, and includes options for external synchronization and clock signals. The work is being done on behalf of, and therefore lists maintainers from Analog Devices, Inc. The series has been tested on actual hardware using an EVAL-AD7985FMCZ evaluation board. An oscilloscope was used to validate that the generated PWM signal matched the requested one.
