ADV7179BCP - 10-Bit NTSC/PAL Video Encoder | Analog Devices
Référence : ADV7179BCP ✗ Fin de vieADV7179BCP Présentation
A video encoder is a signal-conversion integrated circuit that transforms digital video into legacy analog composite or component output. In the product hierarchy, the ADV7179BCP is a video encoder, interface IC, signal-processing semiconductor, and communications-interface component. It bridges a digital video pipeline and displays or capture equipment that still require NTSC or PAL baseband signals.
Key features include three 10-bit DACs, support for PAL and NTSC systems, a 40-LFCSP-WQ package with an exposed pad, and a stated operating temperature range of -40°C to +85°C. According to the Analog Devices ADV7174/ADV7179 data sheet, the timing specifications apply with a 3.3 V analog supply, a 1.235 V reference, and a 150 Ω RSET resistor. The encoder also supports WSS and CGMS-A data control generation.
The digital input follows the CCIR-601 4:2:2, 8-bit component-video format, while the encoder generates synchronized analog baseband outputs. Output video frames are synchronized with incoming timing reference codes. Optionally, the device accepts or generates HSYNC, VSYNC, and FIELD timing signals, and those pulse widths and positions can be adjusted in master mode. Master and slave timing behavior therefore supports integration with different video timing sources.
Typical uses include legacy broadcast and surveillance equipment, industrial inspection systems, video capture cards, camera interfaces, mobile or portable video products, and embedded systems requiring an analog NTSC or PAL output from a CCIR-601 digital-video source. The three DAC outputs support the device's role as a complete integrated encoder rather than a digital-only processing block.
Designers should preserve the documented supply range, reference configuration, and external RSET value of 150 Ω. The exposed pad requires careful thermal and layout treatment so heat can leave the encoder package, while analog video outputs require suitable termination and trace-impedance control to avoid signal degradation.
This page consolidates manufacturer functionality, verified pricing, lifecycle information, package details, and application-focused design guidance. It also distinguishes documented ADV7179 family alternatives from unrelated cross-package parts so engineers can evaluate replacement options without assuming that similar encoder functions guarantee pin-to-pin compatibility.

Applications typiques
ADV7179BCP convient pour 6 applications: Legacy Broadcast Video Equipment, Industrial Video Inspection, Security Camera Video Output, Video Capture and Frame Conversion, Portable and Embedded Video Products, Telecommunications and Network Video.
Legacy Broadcast Video Equipment
The ADV7179BCP fits legacy broadcast equipment that receives digital component video but must provide an analog NTSC or PAL baseband output. Its 3.0 V to 3.6 V analog operating range, three 10-bit DACs, and CCIR-601 4:2:2 8-bit input provide an integrated conversion path without a separate external video DAC stage. The encoder synchronizes output frames with incoming timing reference codes and can optionally generate HSYNC, VSYNC, and FIELD signals, making it useful in monitoring, switching, and capture subsystems that still expose analog television connections. The main engineering trade-off is lifecycle risk: because the part is obsolete and not recommended for new designs, it is most appropriate for sustaining an existing installation rather than initiating a long-life platform.
Recommandé
Industrial Video Inspection
The ADV7179BCP can serve as the analog-video output stage in an industrial inspection system whose imaging pipeline produces CCIR-601 4:2:2, 8-bit component data. Its NTSC and PAL compatibility and three 10-bit DAC outputs allow the same encoder to feed analog displays, recorders, or long-distance monitoring equipment across different regional television standards. The documented -40°C to +85°C operating range supports industrial temperature conditions, although enclosure temperature and converter heat must be checked separately because junction-thermal data was not provided. Engineers should keep analog outputs away from digital clocks and switching supplies, control impedance on the video paths, and use the exposed pad as both an electrical and thermal connection according to the manufacturer footprint.
Recommandé
Security Camera Video Output
The ADV7179BCP is applicable to surveillance cameras and camera-interface modules that need a conventional analog baseband output from a digital imaging pipeline. Its three 10-bit DACs support PAL or NTSC generation, while the CCIR-601 4:2:2, 8-bit input can originate from a digital camera or image-processing pipeline. Optional HSYNC, VSYNC, and FIELD generation provides the downstream monitor with the timing required to reproduce interlaced video. The design trade-off is that an obsolete encoder should not be introduced into new security hardware without a supply and quality plan. For an existing camera platform, verify timing polarity, blanking levels, output amplitude, and connector grounding against the target display equipment before production use.
Recommandé
Video Capture and Frame Conversion
The ADV7179BCP fits video-capture and frame-conversion equipment that receives standardized digital component-video data and must bridge it to an analog recording or monitoring chain. The encoder accepts CCIR-601 4:2:2 8-bit data, creates three 10-bit analog outputs, and synchronizes generated video frames with incoming timing reference codes. Master mode adds flexibility by allowing HSYNC, VSYNC, and FIELD pulse widths and positions to be adjusted for a particular capture or display system. Because the part is obsolete, engineers should preserve the existing footprint and validate the full timing interface rather than assuming every ADV7179 family ordering code has identical behavior. Prototype measurements should include synchronization stability, DAC output levels, and compliance with the intended NTSC or PAL system.
Recommandé
Portable and Embedded Video Products
The ADV7179BCP can be used in portable or embedded video products that retain an analog television output for compatibility with legacy displays, docking stations, or service equipment. Its 3.0 V to 3.6 V analog operating range is suitable for a 3.3 V system rail, and the integrated three-DAC architecture reduces the component count compared with a discrete encoder and DAC implementation. WSS and CGMS-A control-data generation can enrich the output where the receiving television or capture system supports those signals. Designers must balance functional simplicity against lifecycle and power constraints: no verified power-consumption, thermal-resistance, or power-management figures are available in the supplied data. Consequently, the exposed-pad layout and measured converter loading should be validated on the final board.
Recommandé
Telecommunications and Network Video
The ADV7179BCP can serve in telecommunications or network-video equipment that bridges digital video transport to an analog branch or service monitor. CCIR-601 4:2:2 8-bit input provides a defined interface from digital video infrastructure, while NTSC/PAL generation and three 10-bit DACs support local baseband monitoring. Optional timing generation and adjustment can help accommodate equipment with different synchronization expectations, and WSS/CGMS-A support can carry service metadata into compatible displays. The implementation must isolate analog video routing from high-speed network and switching circuitry, provide continuous reference and RSET components as documented, and verify composite timing at the connector. Because the encoder is obsolete, it should be restricted to controlled legacy branches unless lifecycle assurance and sourcing controls are in place.

Notes de conception
Follow the official Analog Devices 40-LFCSP-WQ land pattern rather than treating it as a generic QFN footprint. Connect the exposed pad according to the manufacturer recommendation, preserve the specified 1.235 V reference arrangement, and place the 150 Ω RSET component close to its associated pin. Incorrect pad geometry or long reference and RSET traces can alter timing accuracy, output calibration, and channel matching even when the nominal 3.3 V supply is present.
Separate the three analog video outputs from digital timing and clock routes, and provide a continuous ground reference beneath the encoder and its video circuitry. Video signals should use controlled-impedance routing, short return paths, and connector-side return connections to limit reflections and ground potential differences. Although no output impedance or crosstalk figures were supplied, physical separation remains important because these parameters can affect visible artifacts even when the digital conversion itself is correct.
Use the exposed pad as a thermal path with adequate copper and through-vias where permitted by the manufacturer layout, then verify enclosure temperature and actual converter dissipation on the assembled board. The supplied data gives a -40°C to +85°C operating range but no power dissipation, junction resistance, or package thermal resistance. Consequently, no unsupported junction-temperature estimate is presented; thermal qualification should use measured board conditions and the manufacturer thermal model.
Do not assume that every ADV7179 or ADV7174 ordering suffix is automatically interchangeable. The verified evidence distinguishes an active ADV7179KCPZ from the obsolete target and does not provide complete suffix-level pin, grade, or lifecycle data for every candidate. Before substituting a part, compare the official pin table, exposed-pad connection, timing defaults, output levels, temperature grade, and PCB footprint. This check is particularly important when an existing board is being cloned or prepared for long-term production.
