Introduction to FPD-Link Serializers
FPD-Link Serializers are signal conversion chips developed based on the FPD-Link (Flat Panel Display Link) high-speed serial bus protocol. Their core function is to convert parallel CMOS/LVDS display signals into serial differential signals for transmission, making them indispensable signal-conditioning components for embedded display systems such as automotive displays, industrial displays, and high-definition cameras.
Regarding the technological evolution of FPD-Link Serializers technology
In terms of technological evolution, FPD-Link serializers have undergone multiple upgrades to meet varying resolution and bandwidth requirements. The first-generation FPD-Link serializers supported single-channel LVDS output with bandwidths under 1 Gbps, primarily catering to low-to-mid-resolution displays like SVGA and XGA. The second-generation FPD-Link II serializers introduced embedded clock technology-eliminating the need for a separate clock signal and further reducing cabling-supported total bandwidths of up to approximately 3 Gbps, accommodated 1080P resolution, and served as the mainstream solution for early automotive center-stack displays. The third-generation FPD-Link III serializers upgraded the data encoding mechanism to support the simultaneous transmission of high-definition video signals and control data (such as I2C signals) over a single link-a capability known in the industry as "bidirectional transmission over a single cable." They support total bandwidths of up to 12 Gbps, enabling signal transmission for 2K and 4K automotive instrument clusters, center-stack screens, and ADAS high-definition cameras; furthermore, they meet AEC-Q100 automotive-grade reliability standards and operate across a wide temperature range of -40°C to 125°C.
Advantages of FPD-Link Serializers
Compared to other high-speed serial transmission solutions, FPD-Link serializers offer advantages such as a mature protocol, a streamlined system design, and manageable costs. They are highly optimized for embedded, low-bandwidth, high-definition transmission scenarios and-having established a stable supply chain and industrial ecosystem, particularly in the automotive sector-remain a mainstream choice for low-to-medium resolution automotive displays and camera data transmission. However, to meet the demands for higher resolutions and greater bandwidth in automotive displays, an increasing number of new products are shifting toward solutions like V-by-One, LVDS, and Ethernet; meanwhile, FPD-Link serializers continue to undergo bandwidth upgrades to accommodate these higher-specification transmission requirements.
Specific FPD-Link serializer model
The DS90UB638-Q1 is a versatile deserializer capable of receiving serial sensor data from a single source via an FPD-Link III interface. When paired with the DS90UB635-Q1 serializer, the DS90UB638-Q1 receives data from imagers, supporting 2MP/60fps and 4MP/30fps cameras, as well as satellite radars and other sensors (such as ToF and LiDAR). The received data is output via a MIPI CSI-2 compliant interface for interconnection with downstream processors. When the CSI-2 interface is configured for 2-lane operation, an identical MIPI CSI-2 clock lane is provided to enable replicated output. This replication mode creates two copies of the received video stream for use in data logging and parallel processing.
The DS90UB638-Q1 is AEC-Q100 qualified and designed to receive data over 50Ω single-ended coaxial cables. It is ideally suited for Power-over-Coax (PoC) applications; the receiver equalizer automatically adapts to compensate for cable loss characteristics-including cable aging over time-without the need for additional programming.
