Serializer IC Extends Video Transmissions

By Mat Dirjish

In a 2.1 mm x 2.9 mm package, THine’s THCV243 MIPI CSI-2 serializer IC can extend MIPI CSI-2 transmissions beyond 15 meters. 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.

According to THine, higher resolution and/or higher frame rate cameras require MIPI CSI-2 output, which limits transmission range to approximately 1 foot. To extend this distance to 10 feet or more, the THCV243 serializes up to four lanes of MIPI CSI-2 signals and converts it into a single lane of V-by-One HS technology, a high-speed digital interface protocol developed and owned by THine. It supports up to 4 Gb/s per lane, which can extend the transmission of 1080p60 2-Mpixel uncompressed video over long distances.

A companion chip, THCV242, deserializes the V-by-One HS signal generated by the THCV243 back to the original MIPI CSI-2 signal. For more details, take a gander at the THCV243 datasheet.
