Is GS8515 a clocked or single-wire pixel protocol?

GS8515 is a single-wire, self-clocking protocol, with one data line and no separate clock.

Is GS8515 suitable for use on camera?

Rated camera suitability: Suitable for typical broadcast/cinema frame rates. At 9kHz refresh the GS8515 sits in the range that handles common broadcast and cinema frame rates cleanly. (at a 9kHz PWM rate). Confirm it is comfortably flicker-free at your target frame rate.

Does GS8515 support RGBW?

Yes, GS8515 supports RGBW (a dedicated white channel alongside red, green and blue).

Who makes the GS8515 pixel chip?

GS8515 is commonly attributed to Genesis-Systech. ENTTEC is not affiliated with Genesis-Systech.

GS8515 Pixel Protocol

Manufacturer: Genesis-Systech

The GS8515 is a Genesis-Systech DMX512 LED driver IC that decodes a standard DMX512 signal to drive an RGBW (4-channel) fixture with 16-bit per-channel grayscale, running from 7 to 36V in an SOP16 package.

Strengths

16-bit (65536-level) per-channel grayscale for smooth, high-resolution dimming and color mixing
RGBW four-channel output adds a dedicated white channel alongside red, green and blue
Wide 7 to 36V working voltage range and standard DMX512 control, so it drops into conventional DMX installations without a proprietary controller

Limitations

9kHz PWM refresh is solid for broadcast and cinema frame rates but is not an ultra-high-refresh part; the practical bar it clears is camera safety at typical frame rates
As a DMX512 driver IC from a manufacturer with limited English-language datasheet presence, it is documented primarily through first-party Chinese specifications

Overview

The GS8515 is a DMX512 LED driver IC from Genesis-Systech (Shenzhen Junlue Technology). Rather than using a single-wire self-clocked pixel protocol, it receives a standard DMX512 signal over the differential DMX bus and decodes it locally to drive four output channels (RGBW) at 16-bit grayscale resolution. It operates across a wide 7 to 36V working range and ships in an SOP16 package, with a 9kHz PWM refresh rate that keeps output steady across typical broadcast and cinema frame rates. Because it is a DMX512 decoder, the GS8515 is driven by any standard DMX512 source and does not depend on a custom pixel-protocol timing definition. ENTTEC is not affiliated with Genesis-Systech.
