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.

Specifications

Clock TypeDMX512
Color Resolution16 Bits
Physical PackageSOP16
RGBNo
RGBWYes
Output Pixel Voltage7 to 36V
PWM Rate9kHz
Suitable CameraSuitable for typical broadcast/cinema frame rates. At 9kHz refresh the GS8515 sits in the range that handles common broadcast and cinema frame rates cleanly.
Redundant Data LineNo (DMX bus)

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.
