Auxiliary and Specialized Chips

The ICs in this group handle the system's logic: they convert signals between different protocols (for example, from DMX to Single Wire), drive external power transistors, or run specialized indicator panels. Unlike smart LEDs, these ICs act as a "command center" or an intermediate link.

Glossary

Connection Type (Clock Type)

This parameter defines how many wires are required to transmit data and how stable the signal will be.

  • Single Wire: The most widespread standard. Data travels over a single wire. Requires precise timing configuration to work correctly (Period, H0, H1, Reset).
  • 2-Wire (Clocked): Uses two wires: one for data (Data), the other for synchronization (Clock). Faster and more stable; eliminates pixel "jitter".
  • Differential DMX: A professional standard (RS-485) that uses two data wires (lines A and B). Transmits the signal over hundreds of meters without loss. Ideal for outdoor façades.
  • Single Wire DMX: A hybrid type. Uses DMX command logic but physically transmits it over a single wire. Simplifies installation while preserving the flexibility of DMX systems.

DMX Speed (kbit/s)

The DMX-512 transmission-speed range the chip adaptively decodes. DMX chips only (Differential / Single Wire DMX); others show ➖.

The controller must output the DMX signal at a speed within this range. If the selected speed exceeds the chip's maximum, the chip won't decode it and the strip stays dark (even though everything is wired correctly). Standard DMX ≈ 250 kbit/s; fast pixel modes raise the speed to 500–750 kbit/s — only chips with a matching ceiling handle them.

Example: a 250–500 chip won't run at 750 kbit/s; a 200–2000 chip handles any speed.

Channels

The number of independent outputs on the chip for color control.

  • 3 channels: Classic RGB (Red, Green, Blue).
  • 4 channels: Usually RGBW (a white channel added for pastel tones) or RGB + Amber.
  • 1–4 or 1–6 (range): Means the chip is universal. It can be configured in software — for example, to drive a single high-power white floodlight or a full RGBW section.
  • 5–12, etc.: Chips with many outputs drive several RGB/RGBW groups at once. Often used in matrix modules.

Color Depth (Bit)

Defines how smoothly the LED changes brightness from 0 to 100%, and the internal control architecture.

Base depth (per channel):

  • 5 bit — 32 levels. LPD6803 style. Low resolution, visible "steps".
  • 7 bit — 128 levels (per the protocol, the most significant bit is used as a marker). LPD8806/8803.
  • 8 bit — 256 levels. The standard for most chips. Slight "steps" visible at very low brightness.
  • 12 bit — 4,096 levels. Noticeably smoother transitions.
  • 16 bit — 65,536 levels. Maximum smoothness. Professional use.

Composite notation (when the chip performs additional internal processing):

  • 8 + 5 bit — 8-bit color per channel + a 5-bit global per-pixel dimmer (32 levels). APA102/SK9822/HD107S architecture. Color control is 8-bit, but pixel brightness is set by a separate 5-bit current divider.
  • 16 + 4 bit gain / 16 + 5 bit gain — 16-bit color control + independent per-channel current adjustment (4 or 5 bit). UCS9812 / WS2816A / UCS8903 / HD108. Essentially two parameters per channel: coarse current adjustment + smooth PWM.
  • 12 + 4 bit gain — 12-bit color + 4-bit per-channel gain. UCS5603.
  • 8 → 12 bit γ — the user sends 8 bits, but internal gamma correction expands it into 12-bit PWM for smoother perception. GS8206/8208.
  • 16 + 4 bit γ — 16-bit color + internal 4-bit γ correction (effective resolution ~20 bit). WS2816B/C series.

PWM Frequency (Hz)

The LED's flicker rate — invisible to the eye, but captured by cameras.

  • Low (< 1000 Hz): black bands will "roll" across the footage when filming with a phone.
  • High (> 2000 Hz): optimal for interiors and amateur video.
  • Ultra-high (8000 to 32000 Hz): the professional "Flicker-Free" standard. The image stays perfectly clean even under slow-motion filming.

Backup Line (Redundant Line)

A technology that keeps the strip alive when a single pixel in the chain fails. Applicability depends on the protocol topology:

  • Chain (daisy-chain) topology (Single Wire, 2-Wire Clocked) — the signal passes from chip to chip: each chip receives data on its DIN (Data Input), takes its own 24/32-bit slot, and forwards the remainder through its DO / DOUT output (Data Output — manufacturers name it differently) to the next chip. If one chip fails, all downstream chips lose the signal. This is where a backup data input makes sense:
    • DIN + BIN — Backup Input, e.g. WS2813, WS2815, WS2818 (WorldSemi)
    • DIN + FDIN — Forward (auxiliary) Data Input, e.g. UCS5603, UCS7604, UCS7614, TM1914, LB1908
    • DATA1+CLK1 + DATA2+CLK2 — a hypothetical second Data+Clock pair for 2-Wire (not implemented in any existing chip in practice)
  • Bus topology (Differential DMX, Single Wire DMX) — all chips are connected in parallel to one shared data line (or to the differential A+B = D+ / D− pair). Each chip listens to the stream independently and takes its own DMX slot. A failure of one chip does not affect the others. A backup line is not needed by design.

Column values:

  • ✅ Yes: The chip has an additional data input (DIN+BIN/FDIN or a similar scheme). If one pixel in the chain fails, the signal bypasses it and the rest of the strip keeps working.
  • ➖ No: The chip has no redundancy scheme — if one chip fails, the whole strip after it goes dark. A backup could be implemented architecturally (chain topology), but it is not present in this chip.
  • ❇️ Not applicable: The chip uses a bus protocol architecture (DMX/RS-485 or single-line bus). A backup is conceptually unnecessary — each chip is independent, so a single failure does not affect the others.
  • ❔ Not specified: The value needs verification.

LS Player Port / LS Converter Port (+Extender)

Indicates whether the corresponding port on the Light Stream device can drive this chip. This refers specifically to the DMX port on the device (LS Player / LS Converter / LS Extender), not to the device as a whole.

  • ✅ Supported: A chip of this type can be connected to this device port directly.
  • ➖ Not supported: A chip of this type cannot be connected to this port (different protocol / connection type).

LS Converter Control Preset / Addressing Preset

The settings to select in the LS Converter for correct operation with the chip. A value of `Auto` means the parameter is detected automatically. `DMX` means the DMX protocol is used. `➖` means the parameter is not applicable (for example, the LS Converter is not used for 2-Wire chips).

Legend

  • ✅ — yes / supported / feature implemented in the chip
  • ➖ — feature not implemented in the chip (but architecturally possible)
  • ❇️ — concept not applicable to the protocol (bus architecture — all chips are independent)
  • ❔ — value not specified, needs verification
