ADV7180WBSTZ - 10-Bit SDTV Video Decoder | Analog Devices
料号： ADV7180WBSTZ ✗ 停产ADV7180WBSTZ 概述
An analog video decoder is a signal-conversion integrated circuit that accepts legacy composite or component video and produces digital component data for subsequent image processing, encoding, capture, or display. Within the broader semiconductor hierarchy, the ADV7180 belongs to the video-processing IC category, uses an analog-to-digital conversion stage, and connects to host processors through a serial digital-video interface. Its ITU-R BT.656 output is designed for direct connection with suitable MPEG encoders, codecs, mobile video processors, and digital video systems.
The manufacturer identifies several functional characteristics of the ADV7180 family. It automatically recognizes NTSC, PAL, and SECAM signals, supports full-featured VBI data slicing with teletext support, and includes a two-wire serial microprocessor interface compatible with I2C. The analog input signal range is 1.0 V. Separate 1.8 V analog, PLL, and digital supplies support low-voltage system design, while the digital I/O supply can operate from 1.8 V through 3.3 V. Power-down and ultralow sleep modes help reduce consumption when the video path is inactive.
The ADV7180 converts standard-definition television signals into 4:2:2 component video data compatible with the 8-bit ITU-R BT.656 interface. Its 4× oversampling architecture supports accurate reconstruction of the incoming analog waveform before digital conversion. The parallel functional blocks include analog input conditioning, automatic standard detection, demodulation, digital conversion, output formatting, VBI processing, and host-register control. The I2C-compatible interface allows a system controller to configure operating registers and monitor decoder status.
Typical uses include analog-video capture systems, video surveillance equipment, broadcast monitoring, industrial inspection equipment, consumer video conversion, and embedded multimedia platforms. A television signal enters the analog input section, passes through standard-detection and decoding circuitry, and leaves the device as serial component-video data for an encoder, codec, processor, or display controller. The decoder can therefore bridge an installed analog-video source to a modern digital video pipeline without requiring the downstream processor to perform analog demodulation.
Designers should verify the analog input topology, clocking, supply sequencing, I/O voltage, and register configuration against the Analog Devices ADV7180 datasheet. Decoupling should follow the datasheet's recommended network, and the serial output routing must preserve signal integrity because video timing and impedance discontinuities can affect downstream capture reliability. The device also requires attention to thermal performance and the 1.0 V analog input range when designing the preceding amplifier or termination stage.
This product page consolidates the confirmed ADV7180WBSTZ capabilities, package information, application guidance, design considerations, and qualified replacement information. It also distinguishes confirmed drop-in options from merely similar devices, helping engineers make PCB, firmware, and production decisions with fewer component-level assumptions.

典型应用
ADV7180WBSTZ 适用于 6 应用s: Analog CCTV Video Conversion, Broadcast Video Monitoring, Industrial Video Inspection, Legacy Video Capture Adapter, Mobile and Embedded Video Modules, Analog Video Test and Measurement.
Analog CCTV Video Conversion
The ADV7180WBSTZ is appropriate for an analog surveillance front end that must convert NTSC, PAL, or SECAM camera signals into digital component-video data. Its automatic standard detection removes the need for separate decoder paths, while the 4:2:2 output and 8-bit ITU-R BT.656 interface provide a standardized handoff to an encoder, codec, or processor. The upstream amplifier must present the documented 1.0 V analog input range. Because surveillance installations can be exposed to temperature extremes, the -40°C to +85°C grade of ADV7180WBSTZ is more suitable than the commercial-temperature ADV7180CBSTZ alternative.
推荐
Broadcast Video Monitoring
Use the ADV7180WBSTZ when a broadcast monitoring system must ingest legacy analog baseband video and pass it into a digital processing chain. Automatic recognition of NTSC, PAL, and SECAM supports equipment intended for international use, and the 4:2:2 component output can feed suitable MPEG encoders or codecs. The 1.8 V analog, PLL, and digital supplies reduce system voltage requirements, while the 1.8 V to 3.3 V I/O range simplifies host integration. Full-featured VBI slicing with teletext support is useful when the monitoring product must preserve closed-caption or other vertical-blanking data.
推荐
Industrial Video Inspection
The ADV7180WBSTZ can serve as the standardized-video decoder in industrial inspection equipment that accepts an analog camera signal but performs analysis digitally. The 10-bit, 4× oversampling conversion architecture provides a suitable path from composite or component video to digital data, while automatic NTSC, PAL, and SECAM detection improves adaptability across equipment configurations. Its industrial and automotive-qualified -40°C to +85°C temperature range supports use in equipment subject to wider thermal variation. The designer must still validate camera-specific amplitude, timing, synchronization, and noise performance at the system level.
推荐
Legacy Video Capture Adapter
The ADV7180WBSTZ is well suited to a legacy-video capture adapter designed to bridge analog television sources with digital acquisition hardware. Its 8-bit ITU-R BT.656 output can connect to a compatible processor, codec, or encoder, eliminating the need to implement analog demodulation downstream. The decoder supports NTSC, PAL, and SECAM automatically, and its VBI slicer can recover teletext or other vertical-blanking information when the application requires it. A practical design must account for the 1.0 V analog input level, separate low-voltage supply rails, host I/O voltage, and the timing requirements of the serial video interface.
推荐
Mobile and Embedded Video Modules
The ADV7180WBSTZ can bridge an analog video source into an embedded multimedia module equipped with an MPEG encoder, codec, or mobile video processor. The 1.8 V analog, PLL, and digital supplies are appropriate for compact low-voltage systems, while the 1.8 V to 3.3 V output range accommodates compatible host interfaces. Power-down and ultralow sleep modes provide options for reducing consumption when the source is inactive. Space-constrained designs must accommodate the 10 mm by 10 mm LQFP footprint, maintain compliant high-speed serial routing, and verify that the source signal can be conditioned to the required 1.0 V input range.
推荐
Analog Video Test and Measurement
The ADV7180WBSTZ can be incorporated into test and measurement instruments that need to decode multiple analog television standards into a common digital representation. Automatic NTSC, PAL, and SECAM detection reduces manual format selection, while the ITU-R BT.656 output enables connection to compatible capture or analysis hardware. The decoder's VBI data-slicing capability is valuable when the instrument must examine teletext or vertical-blanking metadata. For dependable measurements, the analog source, timing reference, termination network, and 1.0 V input range must be calibrated, while the serial output and I2C control connections should follow the datasheet timing and layout guidance.

设计说明
Route the ADV7180WBSTZ analog input, PLL supply, digital supply, clock, and serial video outputs according to the Analog Devices ADV7180 datasheet layout guidance. Place the prescribed decoupling capacitors close to their associated pins and provide a low-impedance ground reference beneath the LQFP thermal pad. The analog input trace should be short, controlled-impedance where applicable, and separated from noisy switching paths. Because the package has 64 leads, inspect every pin assignment against the manufacturer pin-description table rather than relying on package continuity alone.
Design the source network to deliver the ADV7180WBSTZ's documented 1.0 V analog input level with the required amplitude, bandwidth, and impedance. Check DC offset, sync polarity, amplitude variation, and termination before enabling automatic standard detection. For the digital output, preserve the ITU-R BT.656 clock-to-data timing and minimize discontinuities on the serial interface. If the video path also carries VBI data, preserve the required vertical-blanking bandwidth and avoid filtering that would distort recovered teletext information.
Use the Analog Devices ADV7180 datasheet to connect the 1.8 V analog, PLL, and digital supplies and to select the digital I/O voltage from 1.8 V to 3.3 V. A single 1.8 V supply is possible when the host interface permits it. Confirm power-up order, voltage tolerances, capacitor values, and load-current requirements before schematic release. The power-down and ultralow sleep modes should be tested with downstream receivers to confirm that serial-video and clock outputs enter the intended states during inactive periods.
The 64-LQFP package requires adequate copper area and thermal-pad assembly for reliable heat removal. Follow the manufacturer's soldering and land-pattern instructions, including the exposed-pad connection and solder-profile requirements. Estimate junction temperature from actual input-to-output power dissipation in the overall decoder system, and validate it across ambient temperature, load, and PCB copper conditions. Do not substitute a commercial-temperature part merely for convenience when the equipment must operate across the -40°C to +85°C range.
