What is SLVS-EC?

Scalable Low-Voltage Signaling with Embedded Clock, abbreviated SLVS-EC, is a high speed interface standard developed by Sony 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 a good choice for higher speeds or transmission over longer distances.

SLVS-EC features

High speed transmission

SLVS-EC enables the implementation for high speed, high resolution image sensors without adding pins or enlarging the package. It supports up to 5 Gbps/lane.

Multi-lane functionality

Extremely versatile, with exceptional freedom in the connection configuration between image sensors and the FPGA/DSP.

Multi-interface

The base SLVS-EC configuration features 1-8 lanes, and using multiple interfaces enables high speed data transfer.

Multi-sensor

Signals from multiple image sensors can be received by a single FPGA/DSP, for multi-camera systems or similar applications.

Without a clock lane and/or need for wiring of equal length, SLVC-EC affords greater freedom in sensor arrangements.

Multi-stream

Enables simultaneous output of multiple types of images from a single image sensor.

*Multi-stream functionality is implemented in consumer camera sensors.

Easy system implementation
  • 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 adjustement between lanes and is a good choice for long distance transmission.

  • Simple protocol facilitates implementation.
