产品详情

The mobile industry processor interface (MIPI®) model of the ADV7281A (ADV7281A-M) has the same pinout as and is software compatible with the ADV7281-M.

The ADV7281A 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 ADV7281A features 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 external amplifier circuitry.

The standard definition processor (SDP) in the ADV7281A 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 via a MIPI CSI-2 transmitter (Tx) interface, hereafter referred to as MIPI Tx.

The ADV7281A offers short to battery (STB) diagnostic sense inputs and general-purpose outputs.

The ADV7281A is provided in a space-saving LFCSP surface-mount, RoHS compliant, package. The ADV7281A is rated over a −40°C to +105°C temperature range, making it ideal for automotive applications.

The ADV7281A must be configured in accordance with the I2C writes provided in the evaluation board script files.
