Overview
The ADV7281AWBCPZ-M-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. It converts these analog video signals into a YCrCb 4:2:2 video data stream, which is compatible with the 8-bit ITU-R BT.656 interface standard or output via a MIPI CSI-2 interface for the ADV7281-M and ADV7281-MA models.
The ADV7281A, a variant of this series, features a single 10-bit analog-to-digital converter (ADC) and an on-chip differential to single-ended converter, allowing direct connection of differential, pseudo differential, or single-ended CVBS without external amplifier circuitry. The device is ideal for automotive applications due to its operating temperature range of -40°C to +105°C and its RoHS-compliant, space-saving LFCSP package.
