What is Sony's SLVS-EC Camera Interface? | SLVS-EC Specifications
Sony SLVS-EC: You know when you need it!
Sony’s SLVS-EC Camera Interface (Scalable Low Voltage Signaling with Embedded Clock) has quickly established itself as the future of CMOS Sensor Interfacing replacing SLVS and subLVDS as the interface of choice for high-end designs. Many Sony sensors support SLVS-EC exclusively and even other sensor suppliers are starting to adopt this interface as standard. See the Sony SLVS-EC specifications below.

Don’t try and re-invent the wheel!
Macnica Mpression has cost-effective, hardware-verified, FPGA-IP for SLVS-EC supporting multiple FPGA suppliers (Altera preferred, Xilinx option available).
Don’t yoke yourself to an inferior IP partner!
Macnica was first to market with FPGA IP for SLVS-EC v1.2 and first to support SLVS-EC v2.0. Hardware evaluation with Sony IMX420, IMX421, and IMX530 available (EasyMVCopens in a new tab). Full details, pricing, documentation, simulation environment, and more under NDA.
