to the sdp or cp (see table 8 for sampling rates). the analog front end uses differential channels to each adc to ensure high performance in a mixed-signal application. the front end also includes a 12-channel input mux that enables multiple video signals to be applied to the adv7401. current and voltage clamps are positioned in front of each adc to ensure that the video signal remains within the range of the converter. fine clamping of the video signals is performed downstream by digital fine clamping in either the cp or sdp. optional antialiasing filters are positioned in front of each adc. these filters can be used to band-limit standard definition video signals, removing spurious, out-of-band noise. the adcs are configured to run in 4 oversampling mode when decoding composite and s-video inputs; 2 oversampling is performed for component 525i, 625i, 525p, and 625p sources. all other video standards are 1 oversampled. oversampling the video signals reduces the cost and complexity of external anti-aliasing filters with the benefit of an increased signal-to- noise ratio (snr). the adv7401 can support simultaneous processing of cvbs and rgb standard definition signals to enable scart compat- ibility and overlay functionality. a combination of cvbs and rgb inputs can be mixed and output under control of i 2 c registers and the fast blank pin. table 8. maximum adc sampling rates model maximum adc sampling rate adv7401bstz-80 80 mhz ADV7401BSTZ-110 110 mhz adv7401wbstz-110 110 mhz adv7401kstz-140 140 mhz standard definition processor (sdp) the sdp section is capable of decoding a large selection of baseband video signals in composite s-video and yuv formats. the video standards supported by the sdp include pal b/d/i/g/h, pal60, pal m, pal n, ntsc m/j, ntsc 4.43, and secam b/d/g/k/l. the adv7401 can automatically detect the video standard and process it accordingly. the sdp has a 5-line superadaptive 2d comb filter that gives superior chrominance and luminance separation when decod- ing a composite video signal. this highly adaptive filter auto- matically adjusts its processing mode according to video standard and signal quality with no user intervention required. the sdp has an if filter block that compensates for attenuation in the high frequency luma spectrum due to tuner saw filter. the sdp has specific luminance and chrominance parameter control for brightness, contrast, saturation, and hue. the adv7401 implements a patented adaptive-digital-line- length-tracking (adllt) algorithm to track varying video line lengths from sources such as a vcr. adllt enables the adv7401 to track and decode poor quality video sources such as vcrs, noisy sources from tuner outputs, vcd players, and camcorders. the sdp also contains a chroma transient improvement (cti) processor. this processor increases the edge rate on chroma transitions, resulting in a sharper video image. the sdp can process a variety of vbi data services, such as teletext, closed captioning (cc), wide screen signaling (wss), video programming system (vps), vertical interval time codes (vitc), copy generation management system (cgms), gemstar 1/2, and extended data service (xds). the adv7401 sdp section has a macrovision 7.1 detection circuit that allows it to detect types i, ii, and iii protection levels. the decoder is also fully robust to all macrovision signal inputs. component processor the cp section is capable of decoding/digitizing a wide range of component video formats in any color space. component video standards supported by the cp are 525i, 625i, 525p, 625p, 720p, 1080i, 1250i, vga up to sxga @ 75 hz (adv7401kstz-140 only), and many other standards not listed here. the cp section of the adv7401 contains an agc block. when no embedded sync is present, the video gain can be set manually. the agc section is followed by a digital clamp circuit that ensures the video signal is clamped to the correct blanking level. automatic adjustments within the cp include gain (contrast) and offset (brightness); manual adjustment controls are also supported. a fully programmable, any-to-any, 3 3 color space conversion matrix is placed between the analog front end and the cp section. this enables yprpb-to-rgb and rgb-to-ycrcb conversions. many other standards of color space can be implemented using the color space converter. adv7401 rev. b | page 16 of 20 the output section of the cp is highly flexible. it can be config- ured in single data rate mode (sdr) with one data packet per clock cycle or in a double data rate (ddr) mode where data is presented on the rising and falling edges of the clock. in sdr mode, a 16-bit 4:2:2 or 24-bit 4:4:4 output is possible. in these modes hs, vs, and field/de (where applicable) timing refer- ence signals are provided. in ddr mode, the adv7401 can be configured in an 8-bit 4:2:2 ycrcb or 12-bit 4:4:4 rgb/ ycrcb pixel output interface with corresponding timing signals. the adv7401 is capable of supporting an external dvi/ hdmi receiver. the digital interface expects 24-bit 4:4:4 or 16-bit 4:2:2 bit data (either graphics rgb or component video ycrcb), accompanied by hs, vs, de, and a fully synchronous clock signal. the data is processed in the cp and output as 16-bit 4:2:2 ycrcb data. the cp section contains circuitry to enable the detection of macrovision encoded yprpb signals for 525i, 625i, 525p, and 625p. it is designed to be fully robust when decoding these types of signals. vbi extraction of cgms data is performed by the cp section of the adv7401 for interlaced, progressive, and high definition scanning rates. the data extracted can be read back over the i 2 c interface. for more detailed product information about the adv7401, contact your local adi sales
