# MIPI CSI-2 Bandwidth Calculator

> Compute the bandwidth of a MIPI CSI-2 camera interface: from resolution, frame rate and bit depth get the required data rate and check whether the lanes can carry it.

Tool for sizing a MIPI CSI-2 camera link. Enter resolution, frame rate, pixel format (RAW8/10/12/14, YUV422, RGB888) and D-PHY configuration (lane count, lane rate): get the required data rate, lane utilization, headroom and the minimum number of lanes needed. Born from our camera-capture work on STM32.
