Overview

YX1903BIs a three-channel single-line transmissionLEDDrive Control Chip

Utilize unipolar return-to-zero (RZ) data protocol.

YX1903BInternally, it includes a power clamp module, a signal decoding module,

Oscillator module, data regeneration module, output current drive module, etc. Among them

The data regeneration module automatically cascades the input data from this chip after receiving it.

Ensure data shaping and forwarding to maintain data integrity without attenuation during transmission.

YX1903BNo external resistor required.OUT R/G/BPort default output voltage

Flow17mAThe chip's peripheral components are few, simple, and reliable.
