Demands for higher resolution and/or higher frame rate cameras require MIPI CSI-2 output, which are limited to a short transmission range of approximately 1 foot. To extend this distance to 10 feet or more, the THCV243 serializes up to 4 lanes of MIPI CSI-2 signals and converts it into a single lane of V-by-One HS. V-by-One HS technology is a high-speed digital interface protocol developed and owned by THine. It supports up to 4 Gbps per lane which can extend the transmission of 1080p60 2Mpixel uncompressed video over long distances.
This new chip allows engineers to extend MIPI CSI-2 transmission to greater than 15 meters with a 2.1mm x 2.9mm package. It also allows the reduction of a significant number of cables between the camera and processor board by aggregating the GPIO-type bidirectional control signals.
An application example
THCV243’s companion chip, THCV242, deserializes the V-by-One HS signal generated by the THCV243 back to the original MIPI CSI-2 signal.
THCV243’s package size of 2.1 x 2.9 mm allows a small camera form factor, which is a critical requirement for medical endoscope camera applications.
The chipset supports “Sub-Link” that aggregates bidirectional low speed signals, such as GPIO. The separation of the V-by-One HS high speed signal path and Sub-Link enables debugging and gives more choices for physical harnesses including the utilization of Keyssa’s contactless connection for systems benefiting from or requiring a ruggedized, low latency, detachable camera.
The chip will be available at major distributors including Digi-Key and Mouser shortly.
