Gnarly Grey SLVS-EC Interface IP

Sony image sensors have a variety of electrical interfaces depending on rate, resolution and application. For image sensors above 20MP and 30fps the Sony SLVS-EC interface provides high speed connectivity at over 2.3Gbps/lane while eliminating the need for a dedicated clock lane and interpair trace matching.

The Gnarly Grey SLVS-EC Interface IP converts multiple data lanes of SLVS-EC sensor data to pixels and provides access to necessary packet control indicators. It is targeted and optimized for Lattice Semiconductor FPGAs providing real-time video interfacing of Sony SLVS-EC image sensors.
