Product details
Overview
ADV7401BSTZ-110 from Analog Devices is a 10-bit integrated multiformat SDTV/HDTV video decoder and RGB graphics digitizer supporting NTSC/PAL/SECAM composite/S-video, 525p/625p/720p/1080i component video, and VGA–SXGA RGB graphics up to 1280×1024@75 Hz. It features four 10-bit ADCs, 12-channel analog mux, and 12.825 MHz to 110 MHz LLC1 pixel clock output for HDTV STB and PDP display systems.
For engineers reviewing the ADV7401BSTZ-110 datasheet, ADV7401BSTZ-110 pinout, ADV7401BSTZ-110 application, or ADV7401BSTZ-110 equivalent, this device serves as a single-chip solution for legacy analog video decoding, high-resolution graphics digitization, and embedded sync processing in industrial temperature-grade (−40°C to +85°C) consumer and professional AV equipment.
Technical Context
The ADV7401BSTZ-110 integrates two independent processing cores: a Standard Definition Processor (SDP) handling CVBS/S-video with adaptive 2D comb filtering, automatic standard detection, Macrovision detection, and VBI data slicing; and a Component Processor (CP) supporting YPrPb/RGB component formats including 720p and 1080i, with programmable SDR/DDR pixel output modes and 24-bit digital input port compatibility with DVI/HDMI receiver ICs.
It uses a single 28.63636 MHz crystal for all internal clock generation, provides line-locked LLC1 output (12.825–110 MHz), supports SCART fast-blank overlay between CVBS and RGB, and delivers 10-bit digitized pixel streams via configurable 8-/12-/16-/24-bit parallel interfaces with HS/VS/FIELD/DE synchronization signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 10-bit per channel; enables true 8-bit video decoding fidelity with ±0.6 LSB INL at 27 MHz for CVBS inputs. |
| LLC1 Pixel Clock Range | 12.825 MHz to 110 MHz; supports full HD timing for 720p/1080i and SXGA graphics digitization without external PLL. |
| Input Channel Support | 12 analog inputs (AIN1–AIN12); allows direct connection of multiple video sources (CVBS, S-video, RGB, YPrPb) without external multiplexer. |
| Video Standards | PAL/NTSC/SECAM composite & S-video; 525i/625i/525p/625p/720p/1080i component; VGA–SXGA RGB graphics; certified Macrovision detection on CVBS/S-video. |
| Output Interface | 12-bit 4:4:4 or 8-bit 4:2:2 DDR pixel output; enables direct interface to downstream video processors or HDMI transmitters with embedded sync support. |
| Operating Temperature | −40°C to +85°C; qualified for industrial-grade deployment in HDTV STBs, PVRs, and professional scan converters. |
| Power Supplies | AVDD = 3.3 V, DVDD = 1.8 V, DVDDIO = 3.3 V, PVDD = 1.8 V; separate analog/digital/PLL domains minimize noise coupling. |
Pinout & Package
LQFP-100 package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad; thermally optimized for industrial ambient operation with θJA = 30°C/W on 4-layer PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1–AIN12 | Analog Video Inputs | Accept CVBS, S-video Y/C, RGB, YPrPb, or SCART signals; each routed to dedicated 10-bit ADC with fine/coarse clamp control. |
| P0–P40 (selected) | Pixel Data I/O | Configurable 8-/12-/16-/24-bit parallel bus for SDR/DDR YCrCb/RGB output or 24-bit digital RGB input from DVI/HDMI Rx ICs. |
| LLC1 | Line-Locked Clock Output | 12.825–110 MHz pixel clock synchronized to incoming video; drives pixel data valid timing for downstream logic. |
| FB | Fast Blank Overlay Control | Switches real-time between CVBS and RGB analog inputs during SCART mode; enables seamless signal mixing without frame buffer. |
| XTAL / XTAL1 | Clock Input/Output | 28.63636 MHz crystal interface; XTAL accepts oscillator or crystal; XTAL1 connects to crystal second terminal or floats when external clock used. |
| INT | Programmable Interrupt Output | Active-high/low status change indicator (e.g., lock loss, format switch, VBI event); reduces polling overhead in host MCU firmware. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated SDP + CP dual-core architecture | Enables simultaneous decoding of legacy CVBS/S-video and modern component/HDTV signals within one die-eliminates need for discrete decoder chains. |
| 12-channel analog mux with antialias filters | Reduces BOM count by removing external video switches and analog anti-aliasing networks while maintaining SNR >58 dB (luma flat field). |
| VBI data slicer (Teletext/VPS/VITC/CC/CGMS) | Extracts broadcast metadata directly from composite signal-enables EPG, closed captioning, and copy control without secondary processor. |
| SCART fast blank overlay | Hardware-level switching between CVBS and RGB analog paths under FB pin control-supports real-time picture-in-picture and menu overlays in CRT/LCD TVs. |
| 24-bit digital input port | Accepts RGB pixel data from DVI/HDMI receiver ICs (e.g., ADV7611), enabling hybrid analog/digital video processing pipelines in AV receivers and STBs. |
| Industrial temperature range (−40°C to +85°C) | Validated for continuous operation in enclosed HDTV chassis and set-top box environments without derating or forced cooling. |
Applications
| LCD/DLP Rear Projection HDTV | HDTV Set-Top Box with PVR |
|---|---|
Use Scenario: Decoding analog broadcast signals (PAL/NTSC) and component video inputs (720p/1080i) for display on large-format rear-projection panels with minimal latency. IC Role / Device Role / Timing Role: Primary video decoder and graphics digitizer; generates LLC1-synchronized pixel stream and HS/VS/FIELD timing for panel controller interface. Use Value: Single-chip integration eliminates discrete ADCs, sync extractors, and color-space converters-reducing board area by >35% versus multi-chip solutions. |
Use Scenario: Capturing analog video inputs (composite, S-video, RGB) for time-shifted playback and recording onto hard disk in broadcast-quality resolution. IC Role / Device Role / Timing Role: Front-end digitizer feeding MPEG encoder; provides VBI data (CGMS, WSS) for conditional access and recording control. Use Value: Certified Macrovision detection and CGMS extraction enable compliant recording behavior per broadcast licensing requirements. |
| PDP HDTV Display System | DVD Recorder with Progressive Scan |
Use Scenario: Converting legacy analog video sources (VCR, camcorder) and progressive-scan RGB PC outputs into native plasma panel timing format. IC Role / Device Role / Timing Role: Graphics digitizer for SXGA (1280×1024@75 Hz) RGB inputs; outputs DDR 12-bit 4:4:4 YCrCb aligned to panel pixel clock. Use Value: 140 MHz-capable ADC path (enabled in ADV7401BSTZ-110) ensures distortion-free digitization of high-bandwidth PC graphics signals. |
Use Scenario: Digitizing progressive-scan component video (525p/625p) from DVD players or game consoles for re-encoding and storage. IC Role / Device Role / Timing Role: Component processor handling YPrPb inputs; applies 2D comb filtering and chroma/luma enhancement before encoding. Use Value: Adaptive digital line length tracking (ADLLT™) maintains stable lock on unstable progressive-scan sources-preventing frame tearing during recording. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7403BSTZ | Same pinout, identical SDP/CP architecture, but supports higher LLC1 up to 140 MHz and adds HDMI receiver functionality. | Targeted at next-gen designs requiring HDMI input alongside analog decoding-requires additional HDCP key management. | Select ADV7403BSTZ only if HDMI Rx integration and >110 MHz pixel clock are required; ADV7401BSTZ-110 remains optimal for analog-only cost-sensitive STBs. |
| MAX9526ETM+ | Single-core SDTV decoder only (no HDTV/component support); 8-bit ADCs; 40-pin TQFN; no VBI slicing or SCART overlay. | Suitable for low-cost DVD players or portable monitors-lacks 720p/1080i, RGB graphics, or industrial temp rating. | Choose MAX9526ETM+ only for basic NTSC/PAL decoding where HDTV, graphics, or extended temperature are not needed. |
Compared with ADV7403BSTZ and MAX9526ETM+, the ADV7401BSTZ-110 uniquely balances multiformat analog decoding, SXGA graphics digitization, VBI processing, and industrial temperature operation in a single LQFP-100 package-making it the most cost-effective choice for HDTV-ready STBs and PDP/LCD displays requiring both legacy and progressive-scan support.
