Lattice Video Utility Calculator

This comprehensive tool helps FPGA/SoC designers calculate video timing parameters, MIPI D-PHY configurations, and bandwidth requirements for Lattice Semiconductor devices. Streamline your design process with accurate calculations and industry-standard presets.

Purpose: Provide comprehensive video timing calculations (active area, blanking intervals, pixel clock, frame rates) and MIPI D-PHY parameter optimization for Lattice FPGA/SoC designs. Support both industry-standard presets (CTA/CEA, VESA) and custom configurations with real-time validation and export capabilities.

Target audience: FPGA/SoC designers, display interface engineers, firmware developers, applications engineers, and validation/test teams working with MIPI DSI/CSI and video pipelines. Specifically designed for Lattice CrossLink-NX, Avant, CertusPro-NX/MachXO5, and Certus-NX device families.

Typical use cases:

• Sizing horizontal/vertical blanking for timing closure
• Estimating MIPI lane rates and bandwidth requirements
• Validating sensor/display configurations against device capabilities
• Calculating D-PHY timing parameters for soft D-PHY implementations
• Sharing standardized configurations across design teams
• Converting between pixel and byte clock domains
• Optimizing video pipeline performance for Lattice devices

Who should use this: Teams building camera/display interfaces, prototyping embedded vision systems, or validating board-level video paths on Lattice devices.
