The ADV7282/ADV7282-M automatically detects standard analog baseband Video signals compatible with worldwide NTSC, PAL, and SECAM standards in the form of composite, S- Video , and component Video .
3 The ADV7282 converts the analog Video signals into a YCrCb 4:2:2 Video data stream that is compatible with the 8-bit ITU-R interface standard. The ADV7282-M converts the analog Video signals into an 8-bit YCrCb 4:2:2 Video data stream that is output over a mobile industry processor interface (MIPI ) CSI-2 interface. The analog Video inputs of the ADV7282/ADV7282-M accept single-ended, pseudo differential , and fully differential signals. The ADV7282/ADV7282-M contain a deinterlacer (I2P con-verter) and short to battery detection capability with two STB diagnostic pins. The ADV7282 provides four analog inputs. The ADV7282-M provides six analog inputs and three general-purpose outputs. The ADV7282/ADV7282-M are programmed via a 2-wire, serial bidirectional port (I2C compatible) and is fabricated in a V CMOS process.
4 The ADV7282/ADV7282-M are provided in space-saving, RoHS compliant LFCSP surface-mount packages. The ADV7282/ADV7282-M are rated over the 40 C to +105 C temperature range. This makes the ADV7282/ADV7282-M ideal for automotive applications. Rev. B Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
