+# LVDS-dat

+

+**LVDS** (Low-Voltage Differential Signaling) is an **electrical signaling standard**, not a specific video protocol.

+Whether it’s "parallel" or "serial" depends on how it’s used:

+

+## In Display Interfaces

+- **Old PC laptop panels** (LVDS display interface) use **serialized pixel data**:

+ - Pixel data from a parallel RGB bus is **serialized** into multiple LVDS lanes.

+ - Typically, **3 data pairs + 1 clock pair** for single link (supports up to ~1366×768).

+ - **6 data pairs + 1 clock pair** for dual link (for higher resolutions like 1920×1080).

+ - Each LVDS lane still carries data in a **parallel-to-serial** fashion internally.

+

+## Key Points

+- **LVDS = Serial differential transmission** (each lane is serial).

+- **LVDS display interface** = multiple serial lanes operating in parallel (multi-lane serial).

+- Main goal: lower EMI, higher speed, longer cable runs vs. raw parallel RGB.

+

+## Summary Table

+| Aspect | LVDS (as used in displays) |

+|-------------------------|---------------------------------------------|

+| Signal Type | Differential |

+| Transmission per lane | Serial |

+| Overall interface | Multiple serial lanes in parallel |

+| Typical Usage | Laptop screens, industrial monitors |

+| Speed per lane | Hundreds of Mbps |

+## GM8283 LVDS Transmitter Overview

+

+The GM8283 is a 28-bit parallel-to-serial LVDS transmitter with pre-emphasis, mainly used for the transmission side in video/image transfer applications. It converts 28-bit parallel LVTTL/LVCMOS data and a reference clock into four channels of serial LVDS data streams and one channel of LVDS sync clock. In each clock cycle, 24 bits of RGB data and 3 bits of control data are transmitted across four LVDS serial channels. The input reference clock frequency ranges from 10MHz to 90MHz, with a maximum total data rate of up to 2520Mbps.

+

+### Internal Modules

+

+- **Serializer**: Loads 28-bit parallel data and, triggered by the multi-phase sync clock generated by the PLL, shifts out the data.

+- **Phase-Locked Loop (PLL)**: Generates multi-phase sync clocks for data and clock synchronization.

+- **LVDS Driver**: Converts the four serial data streams and one sync clock from the serializer into LVDS signals for output.

+- **Enable Module**: In standby mode, shuts down internal module currents to enter low-power state.

+

+### Features

+

+- Programmable data gating control: Clock can sample data on either rising or falling edge via RFC control.

+

+### Pin Compatibility

+# VGA-dat

+

+## VGA for raspberry pi

+

+From the birth of the Raspberry-Pi there have been complaints about the lack of a VGA output. That has now been remedied. But only for the B+ and at the cost of losing most of your GPIOs.

+

+The BCM2835 has a parallel display interface on the GPIO pins. I did not publish this in the 2835 datasheet as 50% of the DPI pins where not on the GPIO connector, making it impossible to get any decent video out.

+

+The B+ however has all of the necessary DPI signals brought out. Dom has been working on the software side and the new DPI (read: VGA) driver software has been added to the latest release.

+

+### Resolution & Quality

+

+The VGA output supports the same resolutions as your HDMI one. Thus from 640x480 up to 1920x1024 60fps. At the highest resolution the pixel quality is almost as good as HDMI.

+

+If you look very closely there is a slight pixel crawl. The adapter uses a simple resistor ladder network as digital-to-analogue converter. Therefore the colour quality depends on how well balanced your resistors are.

+

+The video shown uses an adapter with 1% SMD resistors. There is a slight colour banding and with 6 bits per channel you have a maximum of 262144 colours.

+

+

+### Double screen

+In contrast to the composite video, the DPI interface can be run independent of the HDMI. Thus next to the HDMI screen, the VGA can be used as ‘second monitor’. The software for that is still under development but I expect that to arrive in the next two week.

+

+Beware that running two screens at maximum resolution will really eat into your SDRAM bandwidth. In fact it has not tried yet, so it might not be possible.

+

+### Other Display Interfaces

+

+#### 1. **MIPI-CSI** (Camera Serial Interface)

+- **Direction:** Camera → Processor

+- Also uses MIPI D-PHY (similar electrical layer as DSI).

+- Serial, differential, high-speed.

+- Instead of pixel-out, it’s pixel-in.

+

+#### 2. **LVDS** (Low-Voltage Differential Signaling)

+- Parallel pixel data serialized over multiple lanes.

+- Widely used in laptops before MIPI-DSI became popular.

+- Lower data rate per lane (~945 Mbps) but can use many lanes.

+- Simpler than DSI (no packet protocol like DSI).

+

+#### 3. **eDP** (Embedded DisplayPort)

+- Mostly used in laptops and tablets.

+- Based on DisplayPort standard.

+- Packet-based like DSI, but higher bandwidth (multi-Gbps per lane).

+- Supports very high resolutions (4K, 8K).

+

+#### 4. **HDMI**

+- For external displays/TVs.

+- Packetized video + audio.

+- Higher voltage, not as power-efficient as DSI.

+- Not usually used for mobile internal displays.

+

+#### 5. **Parallel RGB / TTL**

+- Old-school direct pixel bus (1 wire per color bit + sync signals).

+- Very high pin count, no serialization.

+- Easy to understand but not good for high resolution.

+

+#### 6. **SLVS-EC** (Scalable Low Voltage Signaling – Embedded Clock)

+- Newer serial interface from Sony and others.

+- Competes with MIPI for camera & display links.

+- Higher speeds than D-PHY in some cases.

+

+---

+

+💡 **Main takeaway:**

+- **MIPI-DSI** = optimized for **internal** mobile/tablet displays, low pin count, low EMI, power-efficient.

+- **LVDS** and **eDP** = laptop displays.

+- **HDMI** = external monitors/TVs.

+- **Parallel RGB** = simple, low-res systems.
