GS8306 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8306D is a Genesis-Systech data-only single-wire LED driver IC using an NRZ self-clocked pixel protocol, delivering 16-bit grayscale at a 31kHz refresh rate over a dual-wire redundant data path, driving two RGB pixels (6 channels) per chip.

Strengths

  • 16-bit grayscale (65536 levels) for smooth, fine-grained dimming and color depth
  • 31kHz refresh rate keeps output flicker-free at high camera frame rates
  • Dual-wire redundant data path provides a backup line for improved reliability in cascaded runs

Limitations

  • RGB-only output with no dedicated white channel, so it cannot drive RGBW pixels
  • Not pre-listed on ENTTEC pixel controllers, so it requires custom pixel-protocol setup with the chip's timing entered manually, and it has little English-language datasheet presence

Overview

The GS8306D is a Genesis-Systech (Shenzhen Junlue Technology) data-only LED driver chip that carries pixel data over a single self-clocked NRZ line, so no separate clock conductor is required. It provides 16-bit (65536-level) grayscale, giving fine control over dimming and color depth, and refreshes at 31kHz, which keeps output comfortably flicker-free for on-camera use. Each chip drives two RGB pixels across 6 channels and operates from a 7 to 24V supply in an ESSOP10 package. A distinguishing feature is its dual-wire redundant data topology: a backup data line lets a run keep passing signal if the primary path is interrupted, improving reliability in cascaded installations. ENTTEC is not affiliated with Genesis-Systech.

Using this protocol with ENTTEC

This is a data-only single-wire SPI-style pixel chip, so it is not pre-listed on ENTTEC pixel controllers. It is supported through ENTTEC's custom pixel-protocol creation, where you add the chip's NRZ timing to generate a working protocol on a pixel controller such as the OCTO or Pixelator.

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