GS8319 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8319 is a Genesis-Systech single-wire RGB LED driver IC with 16-bit grayscale, a 30kHz refresh rate, and a dual-wire redundant data path for reliable cascaded pixel runs.

Strengths

  • 16-bit (65536-level) grayscale for smooth low-end dimming and fine color depth
  • 30kHz refresh rate keeps output comfortably flicker-free for on-camera use
  • Dual-wire redundant data path adds fault tolerance so a single break in the data line does not kill the rest of the run

Limitations

  • RGB-only (three channels), so there is no dedicated white channel for RGBW fixtures
  • Not pre-listed on ENTTEC pixel controllers and has little English datasheet presence, so it requires a custom pixel-protocol setup with the chip timing entered manually

Overview

The GS8319 is a data-only LED driver IC from Genesis-Systech that uses an NRZ single-wire pixel protocol, meaning pixel data travels on a single data conductor with no separate clock line, and each chip regenerates the signal as it passes down the cascade. It drives three PWM channels for RGB output at 16-bit (65536-level) grayscale, refreshes at 30kHz, and operates from a 7.5 to 19V supply. Its defining feature is a dual-wire redundant data topology: a backup data line lets the run keep passing pixel information if the primary link is interrupted, which improves reliability in long installations. The part ships in SOP8 or SOT23-8 packages and includes automatic overload protection. ENTTEC is not affiliated with Genesis-Systech.

Using this protocol with ENTTEC

The GS8319 is a data-only single-wire SPI-style pixel chip, so it is not one of the pre-listed protocols on ENTTEC pixel controllers. It is supported through ENTTEC's custom pixel-protocol creation, where the chip's NRZ single-wire timing is entered to generate a matching protocol.

ENTTEC has been engineering lighting control in Australia since 1999, and shipping LED pixel controllers since the original Pixelator in 2014.
