Mipi A-Phy

The first step is now taken on the new MIPI A-PHY


We have taken our first steps on the new MIPI A-PHY specification, aiming for the automotive industry. Ethernet is becoming strong in vehicles but it isn’t suitable for every application since there may be unpredictability in the transmission time or latency when streaming some data from a sensor to the “processor”. The A-PHY support real high-speed data streaming both from the sensors to the “processor” and to the displays.

The MIPI Alliance has started a collaboration with experts from the automotive industry

BitSim is a member of the MIPI Alliance (www.mipi.org), an influential standardization organization within the mobile industry which has successfully developed a number of industry standards for various well-used and established interfaces for camera sensors, displays, storage, power and audio etc.
For some time, a collaboration has been initiated by companies active in the automotive industry, with both car manufacturers and subcontractors to enhance existing or develop new interface specifications for automotive applications.

For short distances in camera applications, MIPI CSI-2 is already used in the automotive industry. BitSim has its own IP block, Bit-MIPI CSI-2, used by customers in different industry segments.

Now, this cooperation will cover solutions for longer distances, up to 15 m, for camera and radar sensors.
Since there will be up to eight cameras in modern cars in the near future, the 40 cm that MIPI CSI-2 can handle today is not enough.

BitSim’s IP, Bit-MIPI CSI-2 used in Flir’s new generataion of thermal cameras, the EXX-Series

Flir Systems is using BitSim’s FPGA-IP, Bit-MIPI CSI-2 in their newly launched advanced thermal cameras. Read more.

The MIPI Alliance, the non-profit corporation that brings the mobile industry together, has standardized the interface between the camera/image sensor and the receiving electronics (host processor or similar) for further image processing, through a high-speed serial interface, the MIPI CSI-2.

The market for image sensors is increasing by over 10% annually, with the consumer and automotive markets leading this growth.

With MIPI CSI-2, the camera providers can reach the market faster with this standardized way of interacting with the sensors: at a faster speed, at a higher resolution, or more cost effectively.

Today, MIPI CSI-2 is also used in other areas, such as test and measurement, industrial or medical markets.

Statement from our customer FLIR

BitSim has supported us in an exemplary way, and BitSim’s IP is one important part of the complete effort that made us reach the market faster in launching our new advanced thermal imaging cameras”, says Rikard hunell, Vice President Sourcing & Strategic Planning of Flir.
