Sony's high-speed camera interface standard SLVS-EC 

Scalable Low-Voltage Signaling with Embedded Clock (SLVS-EC), is a high-speed interface standard developed by Sony Semiconductor Solutions Corporation (SSS) for fast, high-resolution image sensors. The interface's simple protocol makes it easy to build camera systems. Featuring an embedded clock signal, it is ideal for applications that require larger capacity, higher speed, or transmission over longer distances. While introducing a wide range of SLVS-EC compliant products, SSS will continue to promote SLVS-EC as a standard of interface for industrial image sensors that face increasing demands for more pixels and higher speed.

Enables implementation for high-speed, high-resolution image sensors without adding pins or enlarging the package. Supports up to 5 Gbps/lane. (As of November 2020.)

Uses the same 8b/10b encoding as in common interfaces. Can be connected to FPGAs or other common industrial camera components. With an embedded clock signal, SLVS-EC requires no skew adjustment between lanes and is a good choice for long-distance transmission. Simple protocol facilitates implementation.

SLVS-EC is standardized by the Japan Industrial Imaging Association (JIIA)


  1. why not just jump to a PCIe?

    1. I believe it has something to do with ECC, jitter and specific data pattern. 4.752Gbps per lane is however equivalent of PCIe 2.0, so PCIe 4.0/5.0 would make more sense IMO.

  2. Seemed to me, that this is a subset of MIPI CSL M-PHY with some proprietary extensions, which make it subject to licensing ...
