Is GS8523 a clocked or single-wire pixel protocol?

GS8523 is a single-wire, self-clocking protocol, with one data line and no separate clock.

Is GS8523 suitable for use on camera?

Rated camera suitability: Suitable for typical broadcast/cinema frame rates. At a 9.5kHz refresh rate the GS8523 sits in the mid band, comfortable for common broadcast and cinema frame rates. (at a 9.5kHz PWM rate). Confirm it is comfortably flicker-free at your target frame rate.

Does GS8523 support RGBW?

No, GS8523 is RGB only, with no dedicated white channel.

Who makes the GS8523 pixel chip?

GS8523 is commonly attributed to Genesis-Systech. ENTTEC is not affiliated with Genesis-Systech.

GS8523 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8523 is a Genesis-Systech DMX512 LED driver IC in an SOP8 package that decodes a standard DMX512 signal to drive a 3 channel RGB pixel with 16-bit (65536 level) grayscale at a 9.5kHz refresh rate, with automatic address coding.

Specifications

Specification	Detail
Clock Type	DMX512
Color Resolution	16 Bits
Physical Package	SOP8
RGB	Yes
RGBW	No
Output Pixel Voltage	7 to 30V
PWM Rate	9.5kHz
Suitable Camera	Suitable for typical broadcast/cinema frame rates. At a 9.5kHz refresh rate the GS8523 sits in the mid band, comfortable for common broadcast and cinema frame rates.
Redundant Data Line	No (DMX bus)

Strengths

16-bit grayscale (65536 levels per channel) for smooth, high-resolution dimming
Automatic address coding lets each node self-assign its DMX address, simplifying large installs
Wide 7 to 30V operating range in a small SOP8 package, and 9.5kHz refresh keeps it comfortable for common broadcast and cinema frame rates

Limitations

RGB only (3 channels, no dedicated white channel), so it cannot drive an RGBW pixel
As a DMX512 driver IC it has limited English-language datasheet presence, so integration details are best confirmed against the first-party specification

Overview

The GS8523 is a DMX512 LED driver IC from Genesis-Systech (Shenzhen Junlue Technology). Rather than using a self-clocked single-wire pixel protocol, it receives a standard DMX512 control signal and decodes it locally to drive a 3 channel RGB output. It carries 16-bit grayscale (65536 levels per channel) for fine dimming resolution and refreshes at 9.5kHz, which keeps the output comfortable for typical broadcast and cinema frame rates. The chip works across a wide 7 to 30V supply range in a compact SOP8 package, and its automatic address coding feature lets each fixture self-assign its DMX address along the bus, simplifying installation on large runs.
