GS8312 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8312 is a Genesis-Systech single-wire NRZ pixel driver that decodes one data conductor to drive 12 output channels (four RGB pixels) with 16-bit grayscale per channel at a 31kHz refresh rate.

Strengths

  • 16-bit (65536-level) grayscale per channel for smooth low-end dimming and fine color gradation
  • High channel density: 12 output channels (four RGB pixels) driven from a single cascade data line
  • 31kHz refresh rate keeps output flicker-free on camera at broadcast and cinema frame rates
  • Wide 7 to 24V operating supply and compact SOP16 package

Limitations

  • RGB output only, with no dedicated white channel
  • Single-wire cascade with no redundant or backup data line, so a break in the data chain interrupts downstream pixels
  • Not pre-listed on ENTTEC pixel controllers, so it requires a custom pixel-protocol setup with the chip's timing added
  • Little English-language datasheet presence, as documentation is primarily first-party Chinese-language material

Overview

The GS8312 is a data-only LED driver IC from Genesis-Systech (Shenzhen Junlue Technology). It uses an NRZ single-wire self-clocked protocol, meaning pixel data travels on a single conductor with no separate clock line, and chips are chained in a single-wire cascade. Each device drives 12 output channels arranged as four RGB pixels, delivering 16-bit (65536-level) grayscale per channel for fine, smooth color and dimming resolution. It operates over a 7 to 24V supply and refreshes at 31kHz, comfortably above the threshold where flicker becomes visible on camera, so it captures cleanly at typical broadcast and cinema frame rates. The part ships in a compact SOP16 package. This is a first-party specification sourced from Genesis-Systech; ENTTEC is not affiliated with Genesis-Systech.

Using this protocol with ENTTEC

The GS8312 is a data-only single-wire SPI-style pixel chip and is not pre-listed among the protocols on ENTTEC pixel controllers. It can be supported through ENTTEC's custom pixel-protocol creation feature, where you define the chip's NRZ timing so the controller can drive it.

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