CN0263 Evaluation Board Guide
Overview
CN0263 is a circuit that provides a very robust solution, with integrated overvoltage (short-to-battery [STB]) protection, for receiving CBVS video signals in harsh environments. It follows the traditional, proven architecture of isolating/separating a low voltage integrated circuit from the outside world and using an amplifier circuit for signal conditioning and protection.
ADA4830-1 is a single monolithic, high speed difference amplifier that integrates input overvoltage (short-to-battery) protection of up to 18 V with a wide input common-mode voltage range and excellent ESD robustness. It is intended for use as a receiver for differential or pseudo differential CVBS and other high speed video signals in harsh, noisy environments, such as automotive infotainment and vision systems. The ADA4830-1 combines high speed and precision, which allows for accurate reproduction of CVBS video signals, yet rejects unwanted common-mode error voltages.
ADV7180 automatically detects and converts standard analog baseband television signals compatible with worldwide NTSC, PAL, and SECAM standards into 4:2:2 component video data compatible with the 8-bit ITU-R BT.656 interface standard. The simple digital output interface connects gluelessly to a wide range of MPEG encoders, codecs, mobile video processors, and Analog Devices, Inc., digital video encoders, such as the ADV7391.
The ADV7180 and ADA4830-1 are fully automotive qualified, which makes both products ideal for infotainment and visionbased safety systems for automotive applications.
The EVAL-CN0263-EB1Z Board connects to mini-USB connector and is powered by a +7.5 V supply or +7.5 V “wall wart”.
