Lattice Semiconductor and Valens Semiconductor has announced a HDBaseT camera reference design. Up to two cameras can be supported with the output being a HDBaseT CAT5 cable containing both uncompressed video streams. The reference design is powered from the PoE CAT5 cable.
The reference design can accept multiple 1080p sensor cameras and transmit uncompressed high definition video over a single 150m CAT5 Ethernet cable to the DVR (digital video recorder), as well as power and various controls. As opposed to IP cameras, this camera provides a good image quality with zero latency, according to the company. It facilitates the implementation of enhanced video analytics in the DVR with good monitoring quality in real time. This architecture simplifies installation and does not require any configuration or maintenance, and therefore is suitable for analogue and pan tilt zoom camera replacement or upgrade, says the company.
Valens' reference design chipset enables long-reach wired connectivity of uncompressed HD content via a standard single LAN cable. The low power, mid-range LatticeECP3 FPGA device is good for multiplexing the video streams and formatting the data to the Valens HDBaseT Tx driver, claims the company. The FPGA has the necessary memory blocks, FPGA logic, serialisers or deserialisers.
