10-Bit, 4 Oversampled SDTV Video Decoder with Differential Inputs Data Sheet ADV7282A FEATURES GENERAL DESCRIPTION 1 Worldwide NTSC/PAL/SECAM color demodulation support The ADV7282A has the same pinout as and is software One 10-bit ADC, 4 oversampling per channel for CVBS, Y/C, compatible with the ADV7282 with the exception of a updated and YPrPb modes IDENT code. The mobile industry processor interface (MIPI) Analog video input channels with on-chip antialiasing filter model of the ADV7282A (ADV7282A-M) has the same pinout ADV7282A: up to 4 input channels as and is software compatible with the ADV7282-M with the ADV7282A-M: up to 6 input channels exception of an updated IDENT code. Video input support for CVBS (composite), S-Video (Y/C), All features, functionality, and specifications are shared by the and YPrPb (component) ADV7282A and the ADV7282A-M, unless otherwise noted. Fully differential, pseudo differential, and single-ended The ADV7282A is a versatile one-chip, multiformat video CVBS video input support decoder that automatically detects standard analog baseband NTSC/PAL/SECAM autodetection video signals and converts them into YCrCb 4:2:2 component STB diagnostics on 2 video inputs video data streams. Up to 4 V common-mode input range solution Excellent common-mode noise rejection capabilities The analog input of the ADV7282A features an input mux 5-line adaptive 2D comb filter and CTI video enhancement (4-channel on ADV7282A, 6-channel on ADV7282A-M), a Integrated AGC with adaptive peak white mode single 10-bit analog-to-digital converter (ADC) and an on-chip Fast switching capability differential to single-ended converter to accommodate the 2 Integrated I P video output converter (deinterlacer) direct connection of differential, pseudo differential, or single- ACE ended CVBS without the need for external amplifier circuitry. Downdither (8-bit to 6-bit) The standard definition processor (SDP) in the ADV7282A Rovi copy protection detection automatically detects PAL, NTSC and SECAM standards in the 8-bit ITU-R BT.656 YCrCb 4:2:2 output and HS, VS, or field form of composite, S-Video (Y/C) and component. The analog synchronization (ADV7282A) video is converted into a 4:2:2 component video data stream MIPI CSI-2 output interface (ADV7282A-M only) that is output either via an 8-bit ITU-R BT.656 standard- Full featured VBI data slicer with WST support compatible interface (ADV7282A) or via a MIPI CSI-2 Tx Power-down mode available (hereafter referred to as MIPI Tx) interface (ADV7282A-M). 2 2-wire, I C-compatible serial interface The ADV7282A also feature a deinterlacer for interlaced to Qualified for automotive applications 2 progressive (I P) conversion. 40C to +105C temperature grade 32-lead, 5 mm 5 mm, RoHS compliant LFCSP The ADV7282A offers short to battery (STB) diagnostic sense inputs and general-purpose outputs. APPLICATIONS The ADV7282A is provided in a space-saving LFCSP surface- Advanced driver assistance mount, RoHS compliant package. The ADV7282A is rated over Automotive infotainment the 40C to +105C temperature range, making it ideal for DVRs for video security automotive applications.
