FPD-LINK Transmitter

Convert Pixel Data Streams to an FPD-LINK Video Stream

Related Products

Due to the higher demand for better displays, bridging applications has become increasingly popular. One very common application interface is the Flat Panel Display Link (FPD-LINK) interface. The Low Voltage Differential Signaling (LVDS) standard is commonly used for high-speed differential interface in consumer devices, industrial control, medical and automotive. The LVDS interface offers low voltage, low power and improved signal integrity advantages over single-ended technology. Applications such as Channel Link, FPD-Link, and Camera Link use LVDS interface for physical layer.

7:1 LVDS interface is a popular standard for source synchronous interfaces which consist of multiple data bits and clocks. Typically, 1 channel of 7:1 LVDS interface consists of 5 LVDS pairs (1 clock, 4 data) depending on the data type it supports.

Lattice’s OpenLDI/FPD-LINK/LVDS Transmitter Interface IP translates DSI video streams such as MIPI DSI Display Interface and others to LVDS interface for an FDP-Link connection to displays.
