Is GS8513 a clocked or single-wire pixel protocol?

GS8513 is a single-wire, self-clocking protocol, with one data line and no separate clock.

Is GS8513 suitable for use on camera?

Rated camera suitability: Suitable for typical broadcast/cinema frame rates (at a 9kHz PWM rate). Confirm it is comfortably flicker-free at your target frame rate.

Does GS8513 support RGBW?

No, GS8513 is RGB only, with no dedicated white channel.

Who makes the GS8513 pixel chip?

GS8513 is commonly attributed to Genesis-Systech. ENTTEC is not affiliated with Genesis-Systech.

GS8513 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8513 is a Genesis-Systech DMX512 LED driver IC in an SOP8 package that decodes a standard DMX512 signal to drive 3-channel RGB pixels with 16-bit (65536-level) grayscale at a 9kHz refresh rate over a 7 to 36V supply.

Specifications

Strengths

16-bit grayscale (65536 levels) per channel for smooth, fine-grained dimming and colour transitions
Wide 7 to 36V operating supply, flexible across common LED strip and module voltages
Standard DMX512 decoding in a compact SOP8 package, driven by any DMX512 source without a custom pixel protocol
9kHz refresh rate suitable for typical broadcast and cinema frame rates

Limitations

RGB only (3 channels), with no dedicated white channel
Little English-language datasheet presence, as documentation is primarily first-party Genesis-Systech material

Overview

The GS8513 is a DMX512 LED driver IC from Genesis-Systech (Shenzhen Junlue Technology), supplied in a compact SOP8 package. Rather than using a self-clocked single-wire pixel protocol, it receives and decodes a standard DMX512 control signal directly at the fixture and drives a 3-channel RGB output. It provides 16-bit grayscale per channel (65536 levels), which supports smooth, fine-grained dimming and colour blending, and operates from a wide 7 to 36V supply, making it flexible across common LED strip and module voltages. Its 9kHz PWM refresh rate falls comfortably in the range suitable for typical broadcast and cinema frame rates. Because the part is a DMX512 decoder, it is driven by any standard DMX512 source and does not require a custom pixel protocol definition. ENTTEC is not affiliated with Genesis-Systech.
