Overview
The ADV7280BCPZ-RL, produced by Analog Devices Inc., is a versatile one-chip, multiformat video decoder. This device 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. The ADV7280 converts these analog video signals into an 8-bit YCrCb 4:2:2 component video data stream that is compatible with the ITU-R BT.656 interface standard. It is fabricated in a 1.8 V CMOS process and is available in a 32-lead LFCSP package, making it ideal for space-constrained portable applications.
