Product details
Overview
ADV7181CBCPZ-REEL from Analog Devices is a 10-bit integrated multiformat SDTV video decoder and RGB graphics digitizer supporting NTSC, PAL, SECAM, 525p/625p, 720p, 1080i, and SXGA (1280×1024@60 Hz) graphics digitization. It features four 10-bit ADCs sampling up to 110 MHz, 12-bit DDR/8–20-bit SDR pixel output, and industrial temperature range (−40°C to +85°C). Used in HDTV STBs with PVR and LCD projectors for analog-to-digital video conversion.
For engineers reviewing the ADV7181CBCPZ-REEL datasheet, ADV7181CBCPZ-REEL pinout, ADV7181CBCPZ-REEL application, or ADV7181CBCPZ-REEL equivalent, key selection criteria include component video support (YPrPb/RGB), dual-standard-definition-and-HDTV decoding capability, programmable interrupt output, SCART fast-blank overlay control, and compliance with ITU-R BT.656 output formatting.
Technical Context
The ADV7181CBCPZ-REEL integrates two independent processing paths: a Standard Definition Processor (SDP) handling composite/S-Video with 5-line 2D comb filtering and automatic PAL/NTSC/SECAM detection, and a Component Processor (CP) supporting YPrPb/RGB inputs including 720p/1080i and graphics up to SXGA. Both paths share a unified 6-channel analog front end with four 10-bit ADCs and configurable clamping.
It delivers pixel data via flexible output interfaces: SDR (8-/10-/16-/20-bit) and DDR (12-bit 4:4:4 RGB or 8-/10-bit 4:2:2 YCrCb), synchronized to a line-locked LLC clock (12.825–110 MHz). Timing is derived from a single 28.63636 MHz crystal, with subcarrier lock (SFL) and field/DE/HS/VS outputs for system-level synchronization.
Key Specifications

Pinout & Package
ADV7181CBCPZ-REEL uses a 64-lead, 10 mm × 10 mm Pb-free LFCSP_VQ package with exposed paddle (Pin 65, EPAD) requiring solder connection to ground for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1–AIN6 | Analog video input channels | Supports simultaneous CVBS, S-Video, YPrPb, and RGB sources; internal mux eliminates external switching ICs. |
| P0–P19 | Pixel data output bus | Configurable 8-/10-/12-/16-/20-bit parallel output; DDR mode doubles effective throughput for high-resolution graphics. |
| LLC | Line-locked pixel clock output | Provides jitter-controlled clock (12.825–110 MHz) directly usable by downstream FPGA or video processor without PLL re-synthesis. |
| FIELD/DE | Field sync / Data Enable output | In CP mode, functions as DE signal for direct interface to HDMI/DVI transmitter ICs-no glue logic required. |
| FB | Fast blank overlay control input | Enables real-time switching between CVBS and RGB signals for SCART-compliant overlay functionality. |
| INT | Programmable interrupt output | Asserts on SDP/CP status changes (e.g., standard detection, lock loss); reduces polling overhead in embedded firmware. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 5-line 2D comb filter | Delivers >60 dB analog front-end crosstalk suppression and <0.5° differential phase error for NTSC/PAL composite decoding. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video decoder and graphics digitizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7180BCPZ-REEL | Single 10-bit ADC, no component video support, max 54 MHz sampling, no DDR output. | Limited to SD-only (NTSC/PAL) and CVBS/S-Video; unsuitable for 720p/1080i or RGB graphics. | Select only for cost-sensitive SD-only designs where HDTV/component input is not required. |
| MAX9526ETX+T | 10-bit, 40 MHz max sampling, no graphics digitization, no DDR output, supports only CVBS/S-Video. | No YPrPb/RGB component or progressive scan support; lacks SCART overlay and Macrovision detection. | Use when only basic SD decoding is needed and system lacks resources for I²C register management. |
Compared with ADV7181CBCPZ-REEL, ADV7180BCPZ-REEL omits component video and DDR graphics paths-reducing feature set but lowering power and cost; MAX9526ETX+T lacks both HDTV support and programmable overlay, making it suitable only for entry-level SD video capture.

FAQ
What video standards does the ADV7181CBCPZ-REEL support?
The ADV7181CBCPZ-REEL supports NTSC (M/J, 4.43), PAL (B/D/I/G/H, 60, M, N), SECAM (B/D/G/K/L), 525i/625i/525p/625p, 720p, 1080i, and RGB graphics up to SXGA (1280×1024@60 Hz). All standards are auto-detected without firmware intervention. The ADV7181CBCPZ-REEL implements dedicated processing paths for SD (SDP) and component/graphics (CP) signals, ensuring accurate decoding across global broadcast formats and progressive-scan sources.
Does the ADV7181CBCPZ-REEL support DDR pixel output for graphics applications?
Yes, the ADV7181CBCPZ-REEL supports 12-bit DDR 4:4:4 RGB output specifically for graphics digitization, enabling direct interface to HDMI/DVI transmitters. This mode operates at pixel rates up to 110 MHz and uses the FIELD/DE pin as a data enable signal-eliminating external timing logic. The ADV7181CBCPZ-REEL also supports SDR 8-/10-/16-/20-bit YCrCb outputs for video-centric back ends, all synchronized to the line-locked LLC clock.
How does the fast blank (FB) pin function in the ADV7181CBCPZ-REEL?
The FB pin on the ADV7181CBCPZ-REEL controls hardware overlay between CVBS and RGB signals, enabling SCART-compliant mixing without CPU involvement. When asserted, it switches the output path from CVBS to RGB (or vice versa) in real time-critical for automotive backup camera overlays on navigation displays. The ADV7181CBCPZ-REEL processes both signals simultaneously in its analog front end, and the FB pin gates the final pixel stream before output formatting.
Is Macrovision® copy protection detection supported on component video inputs by the ADV7181CBCPZ-REEL?
Yes, the ADV7181CBCPZ-REEL provides certified Macrovision® detection on component video inputs (525i, 625i, 525p, 625p) in addition to composite and S-Video. Detection is performed in hardware within the SDP and CP blocks, and status is reported via I²C registers. This allows system firmware to enforce recording restrictions without offloading analysis to host processors-ensuring compliance in PVR-enabled HDTV STBs using the ADV7181CBCPZ-REEL.
What is the recommended crystal frequency for the ADV7181CBCPZ-REEL?
The ADV7181CBCPZ-REEL requires a 28.63636 MHz fundamental-mode crystal connected between XTAL and XTAL1 pins. This frequency is used to generate all internal clocks-including the line-locked LLC output-and ensures precise subcarrier recovery for NTSC/PAL decoding. The ADV7181CBCPZ-REEL also accepts an externally driven 28.63636 MHz CMOS clock on XTAL if crystal layout constraints exist, but crystal mode is preferred for optimal jitter performance.
