Reducing Bias Noise in PHY1075 Applications
要約:The Phyworks PHY1075, a combined laser driver/limiting amplifier with digital diagnostics, can have noise on the laser bias output in common anode configuration. The noise is in the form of a 100Hz repetitive glitch, at an approximately 2.5mA magnitude. This application note details the noise measurements taken and suggests various methods to reduce bias noise in an edge-emitting laser application.
