Overview

SmartDV’s MIPI CSI-2 Transmitter IP is a silicon-proven, high-performance camera interface solution engineered for SoC designs requiring reliable, high-bandwidth image data transmission across mobile, automotive, AI/ML, industrial, and medical imaging applications. Fully compliant with MIPI CSI-2 v4.2, MIPI D-PHY v3.0, and MIPI C-PHY v3.1, it delivers complete transmitter-side CSI-2 functionality with support for both D-PHY and C-PHY physical layers, enabling data rates up to 9 Gbps per lane on D-PHY and up to 3 Gsps per trio on C-PHY.

Designed to address the full breadth of modern imaging transmission requirements, the IP supports an extensive pixel format library spanning RAW, RGB, and YUV data types, multiple virtual channels, multi-lane configurations up to 8 lanes on D-PHY, and advanced features including LRTE, Alternate Low Power State (ALPS) in C-PHY mode, and data scrambling. Its flexible interleaving support for both data type and virtual channel transmission makes it a versatile, production-ready solution for the most demanding camera and imaging subsystem designs.

Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its PPI interface for seamless C-PHY and D-PHY integration, pixel-level video stream interface with up to four pixels per clock, and comprehensive interrupt support enable fast integration and confident design bring-up across a wide range of process nodes and imaging applications.
