产品详情

The ADV7280A has the same pinout as and is software compati-ble with the ADV7280. The mobile industry processor interface (MIPI®) model of the ADV7280A (ADV7280A-M) has the same pinout and is software compatible with the ADV7280-M.

All features, functionality, and specifications are shared by the ADV7280A and the ADV7280A-M, unless otherwise noted.

The ADV7280A 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 ADV7280A is designed for single-ended input video signals. It features an input mux (4-channel on ADV7280A, 8-channel on ADV7280A-M) and a single 10-bit analog-to-digital converter (ADC).

The standard definition processor (SDP) in the ADV7280A 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 (ADV7280A) or via a MIPI CSI-2 Tx (hereafter referred to as MIPI Tx) interface (ADV7280A-M). The ADV7280A also features a deinterlacer for interlaced to progressive (I2P) conversion.

The ADV7280A is provided in a space-saving LFCSP surface-mount, RoHS compliant package. The ADV7280A is offered in an automotive grade rated over the −40°C to +105°C temperature range, as well as a −40°C to +85°C temperature range, making the device ideal for automotive, industrial, and consumer applications.

The ADV7280A must be configured in accordance with the I2C writes provided in the evaluation board script files.
