产品详情

The ADV7282A has the same pinout as and is software compatible with the ADV7282. The mobile industry processor interface (MIPI®) model of the ADV7282A (ADV7282A-M) has the same pinout as and is software compatible with the ADV7282-M.

All features, functionality, and specifications are shared by the ADV7282A and the ADV7282A-M, unless otherwise noted.

The ADV7282A is a versatile one-chip, multiformat video decoder that automatically detects standard analog baseband video signals and converts them into YCrCb 4:2:2 component video data streams.

The analog input of the ADV7282A features an input mux (4-channel on ADV7282A, 6-channel on ADV7282A-M), a single 10-bit analog-to-digital converter (ADC) and an on-chip differential to single-ended converter to accommodate the direct connection of differential, pseudo differential, or single-ended CVBS without the need for external amplifier circuitry.

The standard definition processor (SDP) in the ADV7282A automatically detects PAL, NTSC and SECAM standards in the form of composite, S-Video (Y/C) and component. The analog video is converted into a 4:2:2 component video data stream that is output either via an 8-bit ITU-R BT.656 standard-compatible interface (ADV7282A) or via a MIPI CSI-2 Tx (hereafter referred to as MIPI Tx) interface (ADV7282A-M). The ADV7282A also feature a deinterlacer for interlaced to progressive (I2P) conversion.

The ADV7282A offers short to battery (STB) diagnostic sense inputs and general-purpose outputs.

The ADV7282A is provided in a space-saving LFCSP surface-mount, RoHS compliant package. The ADV7282A is rated over the −40°C to +105°C temperature range, making it ideal for automotive applications.

The ADV7282A must be configured in accordance with the I2C writes provided in the evaluation board script files.
