It is ideal for automotive cameras, driver information systems, and heads-up displays where EMI reduction and cable cost savings are critical.

HDMI compatibility must be carefully evaluated through bridge circuits or companion serializers (e.g., DS90C387), as the DS90CF388 itself does not natively process HDMI signals but can transport pixel data derived from HDMI sources when properly interfaced.

• Identify whether your system requires point-to-point video transmission over long distances (up to 15m)
• Determine if electromagnetic interference (EMI) reduction is a priority—FPD-Link III uses DC-balanced encoding to minimize emissions
• Assess the need for bidirectional control channels (I²C, GPIO) for camera or display configuration
• Evaluate environmental conditions such as temperature range (-40°C to +105°C junction temp for this device)

Resolution and Timing Support

The DS90CF388VJDX NOPB supports up to 28-bit wide parallel output, enabling high-resolution display interfaces. While it doesn’t directly decode HDMI streams, it can handle video data extracted from HDMI sources via an external HDMI receiver or FPGA.

To ensure compatibility with modern display standards:

• Verify that your video source can output formats supported by the deserializer (e.g., RGB888, CCIR656)
• Confirm the maximum pixel clock frequency (typically up to 154 MHz) aligns with your resolution needs (e.g., 1080p @ 60Hz, WUXGA, etc.)
• Check that the serializer on the transmitting side (e.g., DS90C387 or equivalent) matches the DS90CF388’s capabilities
• Use the TI DS90CF388 datasheet to validate timing diagrams and synchronization signals (HSYNC, VSYNC, PCLK)

Design Tip: For 4K or 3D video applications, consider using multiple DS90CF388 devices in parallel or upgrading to newer GMSL or DSI-based solutions, as FPD-Link III has bandwidth limitations compared to current standards.
