Analog Devices’ new transceivers allow a high-definition video and control link using only basic unshielded-twisted-pair (UTP) cabling and connectors.
To address the rapidly growing use for high-definition (HD) video streams in vehicles, Analog Devices has announced a transceiver series that enables HD video over existing low-cost, low-bulk Unshielded Twisted Pair (UTP) cables and unshielded connectors. This allows OEMs to upgrade easily from standard-definition (SD) cameras to high-definition (HD) cameras and provide the superior resolution and image quality required for today’s automotive camera applications.
The new ADV7990 and ADV7991 transmitters and ADV7380 and ADV7381 receivers use ADI’s Car Camera Bus (C2B) technology to enable significant savings in weight, bulk, cost, and reduce cable-routing constraints when compared to other automotive link solutions, claimed the firm.
Transceivers Bring High-Def Video via Existing Vehicle Cable and Connector Infrastructure
ADI said that the C2B transceivers not only support excellent visual quality over the unshielded infrastructure, but also enable full compliance to the rigorous industry mandates for EMC, EMI, and ESD robustness.
The performance of the innovative cable-compensation design is claimed to support 30-meter cable runs with multiple in-line connections for resolutions up to 2 megapixels at 30 Hz or 1 megapixel at 60 Hz.
“C2B has proven to be a very cost-effective solution and provides seamless transition from mainstream low-resolution NTSC to high-definition cameras, and offers significant value to car manufacturers in reducing cable harness cost and weight,” said Motoki Kanamori, general manager, Advanced Hardware Development Dept., Cockpit Systems Business Unit, Denso Corp. “Denso is excited to work with Analog Devices and use its C2B technology to enable our scalable camera and video-connectivity solutions across vehicle lineups.”
The ADV7990/91 and ADV7380/81 transceivers feature negligible latency along with uncompressed transmission; the bidirectional control channel uses the same cable and thus incurs no additional costs.
These devices support a 75-MHz pixel rate (75 MHz Y, 75 MHz C) “frozen frame” detection while the bidirectional control function supports I2C, interrupt/status and general-purpose I/O (GPIO).
Pricing and Availability
Samples of all the new devices are available now. Production availability for the ADV7990/80 is scheduled in January 2019 while for the ADV7381/91 is scheduled in November 2018.
