ADV7180BCPZ - 10-Bit SDTV Video Decoder | Analog Devices
Teilenummer: ADV7180BCPZ ✗ AbgekündigtADV7180BCPZ Übersicht
A video decoder converts composite, Y/C, or component analog video into digital pixel and timing data. The ADV7180BCPZ belongs to the video decoder hierarchy within mixed-signal and digital signal processing semiconductors. Its internal 10-bit ADC samples CVBS at 4× oversampling, Y/C at 2× oversampling, and YPrPb at 2× oversampling per channel. On-chip antialiasing filtering supports the three analog input channels, while automatic color-standard detection simplifies multistandard system configuration.
The decoder produces 4:2:2 component video compatible with the 8-bit ITU-R BT.656 interface. Its digital output can connect to MPEG encoders, codecs, mobile video processors, and other compatible digital video devices. A two-wire serial microprocessor interface provides I2C-compatible control, allowing software or hardware configuration of the decoder without a large parallel control bus.
ADV7180BCPZ is fabricated using a 1.8 V CMOS process and is designed for low power dissipation in space-constrained systems. The analog signal range is 1.0 V, while separate digital I/O supply capability permits interfacing with systems operating at 1.8 V or 3.3 V. The device also includes a full-featured VBI data slicer with teletext support, a power-down mode, and an ultralow sleep-mode current option.
Typical applications include analog television capture, industrial video inspection, broadcast monitoring, set-top-box video input, security surveillance, and embedded multimedia systems. In each case, the three-channel analog front end and automatic NTSC, PAL, and SECAM detection simplify the signal chain while the BT.656 output provides a standardized digital interface.
PCB implementation should preserve the analog and digital return paths specified by the manufacturer and place decoupling capacitors close to their respective supply pins. Because the LFCSP-VQ package is compact and has many fine-pitch connections, follow the land pattern and exposed-pad assembly guidance in the ADV7180 datasheet. The manufacturer identifies the ADV7180 family as not recommended for new designs, so long-lived or new production programs should confirm lifecycle and sourcing implications before committing the device to a new board.

Typische Anwendungen
ADV7180BCPZ ist geeignet für 6 Anwendungs: Analog Television Video Capture, Industrial Video Inspection, Broadcast Monitoring Equipment, Set-Top Box Video Input, Security Surveillance Systems, Embedded Multimedia and Mobile Video Systems.
Analog Television Video Capture
The ADV7180BCPZ fits analog television capture systems that require automatic handling of worldwide NTSC, PAL, and SECAM inputs. Its 10-bit ADC, 4× CVBS oversampling, and three analog channels provide flexible front-end integration, while the 8-bit ITU-R BT.656 output connects directly to compatible encoders or codecs. The 57.27 MSPS maximum sampling rate and BT.656 output reduce the need for separate conversion stages, although the NRND lifecycle status requires confirmation for long-lived programs.
Empfohlen
Industrial Video Inspection
The ADV7180BCPZ is suitable for industrial inspection equipment that receives composite or component analog video from cameras or legacy machinery. Three input channels allow multiple sources to be selected, and automatic NTSC, PAL, and SECAM detection avoids requiring operators to identify each signal standard. The 1.0 V analog input range and on-chip antialiasing filters support signal conditioning, while the digital BT.656 output can feed a processor for image analysis.
Empfohlen
Broadcast Monitoring Equipment
The ADV7180BCPZ can serve as the decoding front end in broadcast monitoring equipment handling composite baseband television signals. Automatic color-standard detection supports equipment deployed across regions using NTSC, PAL, or SECAM, and the standardized 4:2:2 ITU-R BT.656 output simplifies connection to downstream encoders and codecs. Its full-featured VBI data slicer with teletext support adds value for installations that need ancillary vertical-interval information.
Empfohlen
Set-Top Box Video Input
The ADV7180BCPZ can serve legacy analog-video inputs in a set-top box or media gateway. Its three-channel analog front end supports flexible source selection, while automatic standard detection simplifies compatibility with regional broadcast signals. The 1.8 V CMOS implementation and 1.8 V to 3.3 V I/O range allow the decoder to share a power architecture with modern video logic. The BT.656 output provides a direct, standardized path to an MPEG encoder or codec.
Empfohlen
Security Surveillance Systems
The ADV7180BCPZ fits surveillance installations that retain analog camera links but require standardized digital output for recording or network encoding. Three analog input channels can support multi-camera switching, and the automatic NTSC, PAL, and SECAM detection reduces configuration complexity across mixed camera populations. The 4:2:2 BT.656 interface provides a direct path to compatible compression hardware, while the low-power 1.8 V CMOS process suits compact multi-channel installations.
Empfohlen
Embedded Multimedia and Mobile Video Systems
The ADV7180BCPZ is appropriate for embedded multimedia equipment that accepts analog television video and forwards it to a mobile video processor or codec. Its space-constrained 40-LFCSP-VQ package, three integrated analog channels, and single 1.8 V core architecture support compact designs. The decoder’s BT.656 output avoids a proprietary digital link, while 1.8 V to 3.3 V I/O support allows direct interfacing with processors using different logic levels.

Wichtigste Unterscheidungsmerkmale

- Flexible digital-interface voltage range (vs. ADV7180KCP32Z)
- Three-channel analog front end with antialiasing filtering (vs. TVP5150)
- Standardized 8-bit BT.656 output (vs. SAA7113)
Designhinweise
Follow the manufacturer land pattern and exposed-pad assembly instructions for the 40-LFCSP-VQ package. Place the required input, output, and reference decoupling capacitors close to the associated power pins, with separate analog and digital return-current paths. Avoid routing switching-node or high-current return paths beneath the analog input area, because coupling into the video inputs can degrade picture quality even when the decoder itself is operating correctly.
Maintain the specified 1.8 V analog, PLL, and digital supplies and select the I/O supply according to the downstream BT.656 interface voltage. Use the power-up sequence and decoupling arrangement in the ADV7180 Rev. K datasheet. A single 1.8 V supply arrangement is possible, but the I/O domain must still be configured and filtered correctly for the voltage levels used by the connected processor, encoder, or codec.
Keep analog video traces short, use a continuous ground reference, and separate analog inputs from digital clocks and high-speed switching nodes. The 10-bit internal ADC does not remove the need for clean analog routing because input coupling, impedance discontinuities, and ground contamination can affect decoded images. Confirm termination and filtering values against the application schematics in the manufacturer datasheet rather than substituting generic network values.
Do not treat the ADV7180BCPZ, ADV7180WBCPZ, ADV7180KCP32Z, or ADV7180BCPZ-REEL as automatically interchangeable. Automotive qualification, package dimensions, exposed-pad construction, and ordering suffix can differ. Validate the exact mechanical drawing, pin assignment, temperature grade, and lifecycle status before substitution; a reel designation changes order handling but does not establish electrical or drop-in equivalence by itself.
Compliance-Informationen
The ADV7180 Rev. K datasheet identifies automotive-qualified family variants and operating-temperature grades, but the exact compliance declarations for ADV7180BCPZ are not stated in the available manufacturer snippets.
