DLPS074 February 2017 DLPC4422
The DLPC4422 controller supports limited, internally-controlled, spread spectrum clock spreading on the DMD interface. The purpose of this is to frequency spread all signals on this high-speed, external interface to reduce EMI emissions. Clock spreading is limited to triangular waveforms. The DLPC4422 controller provides modulation options of 0%, +/-0.5% and +/-1.0% (center-spread modulation).
