Supported Video Protocols
As one of the companies participating in the founding of the CoaXPress® Consortium, we have been extensively involved in the technical creation and development of the CoaXPress specification and protocol for sending high-speed data and video signals over copper cables. This makes us an expert in this field. We also have a long history of supporting the High-Definition Serial Digital Interface (HD-SDI), which uses the SMPTE protocol for sending uncompressed high-speed video over copper cabling.
This technology is used for transmission of uncompressed, unencrypted digital video signals as defined by the CoaXPress standard. Signals can be transmitted up to 300m over copper cable depending on the transmission speed.
Key Advantages of Our CoaXPress Solutions:
- 1.25 Gbps to 12.5 Gbps downlink speeds
- 20 and 40 Mbps uplink control signals
- Up to 13W of power delivered to camera over cable
- Space-saving 4 × 4 mm, 16-pin QFN package
This protocol, which is based on the SMPTE standard, is used for the transmission of uncompressed, unencrypted digital video signals and, optionally, embedded audio and time code. Signals can be transmitted up to 300m over copper cable depending on the transmission speed. HD-SDI has been widely adopted in security and surveillance camera and video applications.
Key Advantages of Our HD-SDI Solutions:
- 1.25 Gbps to 3.125 Gbps downlink speeds
- 5 Mbps uplink control signals
- Up to 13W power over delivered to camera over cable
- Space-saving 4 x 4 mm, 16-pin QFN package
We Offer These Solutions for Your Design
Our auto-adaptive coaxial cable video equalizers enable the signal recovery performance to automatically adapt to compensate for different cable lengths, varying temperatures, system aging and other factors. They support simultaneous video downlink, uplink for camera control and power over a single coaxial cable and are designed for the lowest-achievable power consumption to reduce the amount of wasted energy and unwanted heat within systems.
Our cable drivers enable frequency separation on a single copper cable to allow video, control and power signals to be transmitted simultaneously without interference.
Transceivers (Equalizers/ Transmitters/Repeaters)
Our transceivers are chipsets consisting of a transmitter that is integrated into a camera and an equalizer that is integrated into the frame grabber on the system head end. Our single-chip transceiver devices also feature integrated Clock-Data-Recovery (CDR), which enables them to also be used as cable extenders/repeaters. Real-time cable link signal integrity test capability ensures link quality at all times and low-frequency clock recovery for camera-side devices.
Video cameras are used for digital image processing systems in many industries. Find out how our solutions are meeting the imaging challenges in these key applications:
