Is GS8512 a clocked or single-wire pixel protocol?

GS8512 is a single-wire, self-clocking protocol, with one data line and no separate clock.

Is GS8512 suitable for use on camera?

Rated camera suitability: Suitable for typical broadcast/cinema frame rates (at a 12kHz PWM rate). Confirm it is comfortably flicker-free at your target frame rate.

Does GS8512 support RGBW?

No, GS8512 is RGB only, with no dedicated white channel.

Who makes the GS8512 pixel chip?

GS8512 is commonly attributed to Genesis-Systech. ENTTEC is not affiliated with Genesis-Systech.

GS8512 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8512 is a Genesis-Systech DMX512 LED driver IC in an SOP8 package that decodes a standard DMX512 signal to drive an RGB (3 channel) fixture with 16-bit (65536 level) grayscale at a 12kHz PWM refresh across an 8 to 30V supply.

Strengths

16-bit (65536 level) grayscale per channel for smooth, high-resolution dimming
Wide 8 to 30V operating supply with 12V/15V/24V single-lamp and 24V dual-lamp series drive options
Standard DMX512 input, so it works with any existing DMX512 source or interface without custom protocol timing

Limitations

RGB only (3 channels), with no dedicated white channel
Little English-language datasheet presence, as it is a first-party Genesis-Systech (Shenzhen Junlue Technology) part

Overview

The GS8512 is a DMX512 driver IC from Genesis-Systech (Shenzhen Junlue Technology). Rather than acting as a self-clocked pixel chip, it receives a standard DMX512 control signal and decodes it locally to drive an RGB (3 channel) LED load, giving 16-bit (65536 level) per-channel grayscale for smooth dimming and a 12kHz PWM refresh rate. It operates over a wide 8 to 30V supply and supports 12V, 15V and 24V single-lamp drive as well as 24V dual-lamp series drive, making it flexible for a range of fixture voltages. The 12kHz refresh sits comfortably within typical broadcast and cinema frame rates, so on-camera flicker is generally not a concern for standard shooting. Because it is a DMX512 decoder, it is driven by any ENTTEC DMX512 source or interface (for example the DMX USB Pro, ODE or Storm) over a standard DMX line, and does not require a custom pixel-protocol definition. ENTTEC is not affiliated with Genesis-Systech.
