GS8526 Pixel Protocol
Manufacturer: Genesis-Systech
The Genesis-Systech GS8526 is a DMX512 LED driver IC that decodes the standard DMX512 protocol to drive a 4-channel RGBW output with 16-bit grayscale at a 9.5kHz refresh rate.

| Suitable Camera | Suitable for typical broadcast/cinema frame rates |
| Redundant Data Line | No (DMX bus) |
Strengths
- 16-bit (65536-level) grayscale for smooth, high-resolution dimming and color mixing
- Native 4-channel RGBW output, adding a dedicated white channel alongside red, green and blue
- Wide 7 to 36V working voltage range plus automatic address coding for simpler fixture setup
Limitations
- The 9.5kHz refresh rate is sufficient for typical broadcast and cinema frame rates but is not an ultra-high-speed part; very demanding high-frame-rate camera work may still show limits
- As a Genesis-Systech component there is little English-language datasheet presence, so timing and channel-mapping details may require the first-party Chinese documentation
Overview
The GS8526 is a DMX512 driver IC from Genesis-Systech (Shenzhen Junlue Technology). Rather than a single-wire self-clocked pixel protocol, it decodes the standard DMX512 differential bus directly and drives four output channels (RGBW) with 16-bit (65536-level) grayscale. It operates over a wide 7 to 36V supply range and refreshes at 9.5kHz, which places it comfortably within typical broadcast and cinema frame rates. The part is offered in SOP16 and SSOP10 packages and includes automatic address coding, letting fixtures self-assign their DMX addresses along the chain. Because it speaks DMX512, a GS8526-based fixture is driven by any standard DMX512 controller or interface. ENTTEC is not affiliated with Genesis-Systech.
