GS8304 Pixel Protocol
Manufacturer: Genesis-SystechThe GS8304D is a Genesis-Systech single-wire, data-only RGBW LED driver IC with 16-bit grayscale per channel, a 48kHz refresh rate, and a dual-wire redundant data path, housed in an SSOP10 package.

Strengths
- 16-bit grayscale per channel (65536 levels) for smooth, deep dimming and fine color gradation
- 48kHz refresh rate keeps output comfortably flicker-free and camera-safe at high frame rates
- Dual-wire redundant data path adds reliability: a single data-line break need not take out the rest of the chain, and the 3MHz data rate supports longer high-resolution runs
Limitations
- Data-only single-wire chip that is not pre-listed on ENTTEC pixel controllers; using it requires setting up a custom pixel protocol with the chip's timing
- Little English-language datasheet presence, as it is a Genesis-Systech (Shenzhen Junlue Technology) part documented primarily in Chinese
Overview
The GS8304D is a data-only LED driver chip from Genesis-Systech, controlled over a single NRZ self-clocked data line with no separate clock conductor. It drives four channels (RGBW) with 16-bit grayscale resolution per channel, refreshes at 48kHz, and operates across a 7.5 to 30V pixel supply range in an SSOP10 package. A distinguishing feature is its dual-wire redundant data topology, which provides a backup data path so a single break in the data chain does not necessarily kill the downstream pixels. It also supports a 16-bit display mode control and a 3MHz data rate for driving longer high-resolution runs. 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 among the supported protocols on ENTTEC pixel controllers. It can still be driven by adding the chip's timing through ENTTEC's custom pixel-protocol creation feature, after which an ENTTEC pixel controller can output to it.
Mapping an installation? ELM, ENTTEC's free LED pixel mapping software, drives the controllers above over Art-Net and sACN, from a single fixture to building-scale maps.
ENTTEC has been engineering lighting control in Australia since 1999, and shipping LED pixel controllers since the original Pixelator in 2014.
