GS8523 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8523 is a Genesis-Systech DMX512 LED driver IC in an SOP8 package that decodes a standard DMX512 signal to drive a 3 channel RGB pixel with 16-bit (65536 level) grayscale at a 9.5kHz refresh rate, with automatic address coding.

Specifications

Clock TypeDMX512
Color Resolution16 Bits
Physical PackageSOP8
RGBYes
RGBWNo
Output Pixel Voltage7 to 30V
PWM Rate9.5kHz
Suitable CameraSuitable for typical broadcast/cinema frame rates. At a 9.5kHz refresh rate the GS8523 sits in the mid band, comfortable for common broadcast and cinema frame rates.
Redundant Data LineNo (DMX bus)

Strengths

  • 16-bit grayscale (65536 levels per channel) for smooth, high-resolution dimming
  • Automatic address coding lets each node self-assign its DMX address, simplifying large installs
  • Wide 7 to 30V operating range in a small SOP8 package, and 9.5kHz refresh keeps it comfortable for common broadcast and cinema frame rates

Limitations

  • RGB only (3 channels, no dedicated white channel), so it cannot drive an RGBW pixel
  • As a DMX512 driver IC it has limited English-language datasheet presence, so integration details are best confirmed against the first-party specification

Overview

The GS8523 is a DMX512 LED driver IC from Genesis-Systech (Shenzhen Junlue Technology). Rather than using a self-clocked single-wire pixel protocol, it receives a standard DMX512 control signal and decodes it locally to drive a 3 channel RGB output. It carries 16-bit grayscale (65536 levels per channel) for fine dimming resolution and refreshes at 9.5kHz, which keeps the output comfortable for typical broadcast and cinema frame rates. The chip works across a wide 7 to 30V supply range in a compact SOP8 package, and its automatic address coding feature lets each fixture self-assign its DMX address along the bus, simplifying installation on large runs.
