Preliminary
MY9931
3 Channels Constant Current LED Driver With
Cascade DMX512 Protocol and Differential Interface
General Description
Features
The MY9931, 3 channels constant current LED driver with 14bits grayscale APDM (Adaptive Pulse Density Modulation) control, supports standard DMX512 protocol and fully differential interface suited for long distance cascade applications. The distinctive DMX512 decoding approach could decode precisely a standard DMX512 signal. The differential interface provides wide common-mode range to support long distance transmission without common-ground power systems.
