10-Bit, 4 Oversampled SDTV Video Decoder with Differential Inputs Data Sheet ADV7281A FEATURES GENERAL DESCRIPTION Worldwide NTSC/PAL/SECAM color demodulation support The mobile industry processor interface (MIPI) model of the 1 One 10-bit ADC, 4 oversampling per channel for CVBS, Y/C, ADV7281A (ADV7281A-M) has the same pinout as and is and YPrPb modes software compatible with the ADV7281-M with the exception 6 analog video input channels with an on-chip antialiasing filter of an updated IDENT code. Video input support for CVBS (composite), S-Video (Y/C), and The ADV7281A is a versatile one-chip, multiformat video YPrPb (component) decoder that automatically detects standard, analog baseband Fully differential, pseudo differential, and single-ended video signals and converts them into YCrCb 4:2:2 component CVBS video input support video data streams. NTSC/PAL/SECAM autodetection The analog input of the ADV7281A features a single, 10-bit, STB diagnostics on 2 video inputs analog-to-digital converter (ADC), and an on-chip, differential Up to 4 V common-mode input range solution to single-ended converter to accommodate the direct connec- Excellent common-mode noise rejection capabilities tion of differential, pseudo differential, or single-ended CVBS 5-line adaptive 2D comb filter and CTI video enhancement without external amplifier circuitry. Integrated AGC with adaptive peak white mode Fast switching capability The standard definition processor (SDP) in the ADV7281A ACE automatically detects PAL, NTSC, and SECAM standards in the Downdither (8-bit to 6-bit) form of composite, S-Video (Y/C), and component. The analog Rovi copy protection detection video is converted into a 4:2:2 component video data stream MIPI CSI-2 Tx output interface that is output via a MIPI CSI-2 transmitter (Tx) interface, Full featured VBI data slicer with WST support hereafter referred to as MIPI Tx. Power-down mode available The ADV7281A offers short to battery (STB) diagnostic sense 2 2-wire, I C-compatible serial interface inputs and general-purpose outputs. Qualified for automotive applications The ADV7281A is provided in a space-saving, LFCSP surface- 40C to +105C temperature grade mount, RoHS compliant, package. The ADV7281A is rated over 32-lead, 5 mm 5 mm, RoHS compliant LFCSP the 40C to +105C temperature range, making it ideal for APPLICATIONS automotive applications. Advanced driver assistance 2 The ADV7281A must be configured in accordance with the I C Automotive infotainment writes provided in the evaluation board script files available at DVRs for video security www.analog.com/ADV7281A.
