This video data stream is compatible with the 8-bit ITU-R BT.656 interface standard. External HS, VS, and FIELD signals can provide timing references for LCD controllers and other video ASICs. The accurate 10-bit analog-to-digital conversion provides professional quality video performance for consumer applications with true 8-bit data resolution. The analog video inputs accept both single-ended, pseudo-differential, and fully differential composite video signals as well as S-Video and YPbPr video signals, supporting a wide range of consumer and automotive video sources. The ADV7182 along with an external resistor divider provide a common-mode input range of 4 V, enabling the removal of large signal, common-mode transients present on the video lines. Common-mode rejection (CMR) values of up to 80 dB can be achieved without the need for external amplifier circuitry. The AGC and clamp restore circuitry allow an input video signal peak-to-peak range to 1.0 V at the analog video input pin of the ADV7182. Alternatively, these can be bypassed for manual settings. The ADV7182 can be protected from short-to-battery (STB) events with standard ac coupling capacitors. The ADV7182 is programmed via a two-wire, serial bidirectional port (I2C® compatible) and is fabricated in a 1.8 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The ADV7182 is provided in a space-saving LFCSP surface-mount, RoHS compliant package. The ADV7182 is available in an automotive grade that is rated over the −40°C to +105°C temperature range. This makes the ADV7182 ideal for automive applications. The ADV7182 is also available in a −40°C to +85°C temperature range, making it ideal for industrial applications. The ADV7182 is a versatile one-chip multiformat video decoder that automatically detects PAL, NTSC, and SECAM standards in the form of composite, S-Video, and component video. The ADV7182 can receive composite signals in either single-ended or differential modes. This makes the ADV7182 ideal for automotive applications. OVERVIEW OF THE ANALOG FRONT END The ADV7182 analog front end (AFE) comprises a single high speed, 10-bit ADC that digitizes the analog video signal before applying it to the standard definition processor. The AFE employs differential channels to the ADC to ensure high performance in mixed-signal applications and to enable differential CVBS to be connected directly to the ADV7182. The front end also includes a 4-channel input mux that enables multiple composite video signals to be applied to the ADV7182. Current clamps are positioned in front of the ADC to ensure that the video signal remains within the range of the converter. A resistor divider network is required before each analog input channel to ensure that the input signal is kept within the range of the ADC (see Figure 23). The choice of this resistor divider ratio provides a common-mode range of up to 4 V. Fine clamping of the video signal is performed downstream by digital fine clamping within the ADV7182. Table 1 shows the three ADC clocking rates that are determined by the video input format to be processed. These clock rates ensure 4× oversampling per channel for CVBS, Y/C, and YPrPb modes. The ADV7182 has a fully differential AFE. This allows for inherent small and large signal noise rejection, improved electromagnetic interference (EMI), and the ability to absorb ground bounce. Support is offered for both true differential and pseudodifferential signals. Table 1. ADC Clock Rates Input Format CVBS Y/C (S-Video)2 YPrPb2 1 2 ADC Clock Rate (MHz)1 57.27 114 172 Oversampling Rate per Channel 4× 4× 4× Based on a 28.63636 MHz clock input to the ADV7182. See INSEL[4:0] in Table 95 for writes needed to set Y/C (S-Video) and YPrPb modes. The ADV7182 converts these analog video formats into a digital 8-bit ITU-R BT.656 video stream. The digital video output stream of the ADV7182 interfaces easily to a wide range of MPEG encoders, codecs, mobile video processors, and Analog Devices, Inc., digital video encoders, such as the ADV7391. External HS, VS, and FIELD signals provide timing references for LCD controllers and other video ASICs. Rev. C | Page 4 of 96 Data Sheet ADV7182 OVERVIEW OF THE STANDARD DEFINITION PROCESSOR The ADV7182 is capable of decoding a large selection of baseband video signals in composite (both single-ended and differential), S-Video, and component formats. The video standards supported by the video processor include PAL B/PAL D/PAL I/PAL G/PAL H, PAL 60, PAL M, PAL N, PAL Nc, NTSC M/NTSC J, NTSC 4.43, and SECAM B/SECAM D/SECAM G/SECAM K/SECAM L. The ADV7182 can automatically detect the video standard and process it accordingly. The ADV7182 has a five-line, superadaptive, 2D comb filter that gives superior chrominance and luminance separation when decoding a composite video signal. This highly adaptive filter automatically adjusts its processing mode according to the video standard and signal quality without requiring user intervention. Video user controls such as brightness, contrast, saturation, and hue are also available with the ADV7182. The ADV7182 implements a patented ADLLT™ algorithm to track varying video line lengths from sources such as a VCR. ADLLT enables the ADV7182 to track and decode poor quality video sources such as VCRs and noisy sources from tuner outputs, VCD players, and camcorders. The ADV7182 contains a chroma transient improvement (CTI) processor that sharpens the edge rate of chroma transitions, resulting in sharper vertical transitions. The ACE offers improved visual detail using an algorithm that automatically varies contrast levels to enhance picture detail. This enables the contrast in dark areas of an image to be increased without saturating the bright areas of an image. This is particularly useful in automotive applications, where it can be important to be able to discern objects in shaded areas. Down dithering from eight bits to six bits enables ease of design for standard LCD panels. The video processor can process a variety of VBI data services, such as closed captioning (CCAP), wide screen signaling (WSS), copy generation management system (CGMS), and teletext data slicing for world standard teletext (WST). Data is transmitted via the 8-bit video output port as ancillary data packets (ANC). The ADV7182 is fully Macrovision® certified; detection circuitry enables Type I, Type II, and Type III protection levels to be identified and reported to the user. The decoder is also fully robust to all Macrovision signal inputs. Rev.

The common-mode rejection (CMR) of this circuit design is critically dependent on the external resistor matching on its inputs. This measurement was performed with 0.1% tolerant resistors, a common-mode voltage of 1 V, and a common-mode frequency of 10 kHz. 3 This is the time that it takes the ADV7182 to detect which video format is present at its input, for example, PAL I or NTSC M. 4 This is the time that it takes the ADV7182 to switch from one (single-ended or differential) analog input to another, for example, switching from AIN1 to AIN2. 2 Rev.
