Core Advantages: Why Do We Need Serializers & Deserializers – Serdes?

• Reduces Pin and Cable Counts: It compresses dozens of data lines into one or a few differential pairs. This significantly reduces IC package sizes, PCB routing complexity, and cable costs.
• Breaks Speed Bottlenecks: Parallel transmission faces severe physical limitations at extreme frequencies (like clock skew). SerDes uses differential signaling and Clock and Data Recovery (CDR) technology to achieve blazing speeds—from several Gbps to hundreds of Gbps.
• Lowers Electromagnetic Interference (EMI): Fewer cables and low-voltage differential signaling drastically reduce both outward EMI radiation and susceptibility to external noise.

4 Typical Application Scenarios for SerDes ICs

With the explosive growth in data traffic, SerDes has become essential infrastructure for modern electronic systems.

1. Automotive Electronics (ADAS & Smart Cabin)

The vehicle interior is a harsh environment. It has high EMI, temperature swings, and intense vibrations. Yet, modern cars must transmit massive amounts of HD video.

• Application: HD cameras (ADAS/surround-view) capture video. A serializer converts this into a high-speed serial stream over coaxial or twisted-pair cables. It travels several meters to the central compute platform. A deserializer then restores it to parallel data for the SoC. Similarly, navigation and entertainment data travel via SerDes to center consoles or digital clusters.
• Typical Protocols: FPD-Link (TI), GMSL (ADI), HSMT (Domestic)

2. Data Centers and Communication Infrastructure

Servers, switches, routers, and their interconnections demand the highest SerDes speeds.

• Application: Optical transceivers inside data centers contain high-speed SerDes modules. They convert parallel electrical signals from server motherboards into serial electrical signals. These drive lasers to transmit optical signals over fiber (reaching 56G, 112G, or even 224G PAM4). Internal server PCIe buses also rely fundamentally on SerDes architecture.
• Typical Protocols: PCIe, Ethernet, Fibre Channel

3. Consumer Electronics and Displays

Our daily devices—phones, PCs, TVs—rely heavily on SerDes.

• Application: Laptop motherboard-to-screen cables typically use eDP. GPUs connect to monitors via HDMI or DisplayPort. Smartphone motherboards connect to screens (MIPI DSI) and cameras (MIPI CSI). Their physical layers rely on SerDes parallel-to-serial conversion to shrink cable sizes.
• Typical Protocols: HDMI, DisplayPort, MIPI, USB (High-speed serial tech starting from USB 3.0)

4. Industrial Automation and Medical Imaging

Critical for precision instruments requiring long-distance, lossless transmission of big data.

• Application: High-speed industrial cameras on machine vision assembly lines send uncompressed, high-framerate images to industrial PCs in real-time. Medical equipment like MRI machines or high-resolution ultrasound probes use SerDes to reliably transmit massive array data from sensors to processing units.
• Typical Protocols: CoaXPress, CameraLink HS

3 Core Categories of SerDes ICs

1. Automotive High-Speed Video SerDes

• Logic & Positioning: Designed for intelligent driving (ADAS cameras, LiDAR) and smart cabins (high-res screens, HUDs). The core requirements are long-distance transmission (meters via coax/twisted pair) and strict AEC-Q100 certification. They typically integrate a forward high-speed data channel and a reverse low-speed control channel (I2C/SPI/UART/GPIO). This allows video, power (PoC), and control signals to run over a single cable.
• Typical Chips:
  • Serializers: DS90UB953TRHBTQ1 (TI) serializes MIPI CSI-2 into FPD-Link III. MAX9275GTN/V+ (Maxim/ADI) supports 3.12Gbps GMSL1.
  • Deserializers: DS90UB964TRGCTQ1 (TI) acts as an FPD-Link III hub. It merges 4 serial inputs into MIPI CSI-2 for the SoC. MAX96752GTN/VY+ (Maxim/ADI) is a GMSL2 deserializer reaching 6 Gb/s.

2. General Tablet and Display Interface SerDes

• Logic & Positioning: Used for traditional consumer electronics, industrial monitors, or laptop screen connections. They solve the issues of wide parallel buses (like 21-bit/28-bit LVTTL/CMOS) which have too many pins and severe EMI. They convert these into low-pin-count, low-radiation standard LVDS or FPD-Link differential signals.
• Typical Chips:
  • Serializers: SN65LVDS93ADGG (TI) converts 28-bit parallel LVTTL into 4-channel LVDS. SN65LVDS301ZXHR (TI) acts as a MIPI DSI to CMOS/LVDS transmitter.
  • Deserializers: DS90C189TWRTDTQ1 (TI) is a low-power dual-pixel FPD-Link (LVDS) receiver for large displays.

3. High-Speed Industrial and FPGA Interconnect SerDes

• Logic & Positioning: Used in industrial automation, medical imaging, or telecom base stations. They handle backplane communication or high-speed data transfer between boards. These chips typically use CML (Current Mode Logic) or high-bandwidth PHY LVDS. They emphasize ultra-low latency, maximum throughput, and pure point-to-point high-speed digital logic docking.
• Typical Chips:
  • Serializers: DS32ELX0421SQE/NOPB (TI) is an FPGA Link serializer. It converts 5-channel differential LVDS parallel data into a single CML serial signal up to 3.125 Gb/s.
  • Deserializers: DS32ELX0124SQE/NOPB (TI) receives the high-speed CML serial signal and accurately restores it to 5-channel differential LVDS data.
