Product details
Overview
ADV7281WBCPZ-MA from Analog Devices is a 10-bit, 4× oversampled SDTV video decoder IC with differential analog video inputs, supporting up to eight CVBS/Y/C/YPrPb input channels and delivering MIPI CSI-2 8-bit YCrCb 4:2:2 output for automotive infotainment and DVR systems.
For engineers reviewing the ADV7281WBCPZ-MA datasheet, ADV7281WBCPZ-MA pinout, ADV7281WBCPZ-MA application, or ADV7281WBCPZ-MA equivalent, key selection considerations include its 8-channel analog input capability, −40°C to +105°C automotive qualification, MIPI CSI-2 interface compliance, and integrated STB diagnostics on two inputs.
Technical Context
The ADV7281WBCPZ-MA implements a fully differential analog front end with on-chip antialiasing filters per channel and supports NTSC/PAL/SECAM autodetection across all input types. Its digital processing block integrates a 5-line adaptive 2D comb filter, CTI enhancement, and ADLLT-based mini-TBC functionality for stable line-locked timing recovery.
It uses a 28.63636 MHz crystal oscillator input (XTALP/XTALN) to drive an internal PLL, generating precise pixel clocks for MIPI CSI-2 transmission at nominal 216 Mbps in interlaced mode. Power domains are segregated: AVDD/DVDD/PVDD at 1.8 V, DVDDIO at 3.3 V, and MVDD at 1.8 V for the MIPI transmitter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 10-bit with 4× oversampling per channel - enables high-fidelity digitization of composite, S-video, and component analog video signals. |
| Input Channels | 8 fully configurable analog inputs (AIN1–AIN8) - supports multi-camera automotive rearview or surround-view systems without external multiplexing. |
| Output Interface | MIPI CSI-2 compliant serial output - reduces PCB routing complexity versus parallel BT.656, enabling direct connection to mobile/application processors. |
| Video Standards | NTSC/PAL/SECAM autodetection - eliminates manual format configuration and ensures robust operation across global broadcast and legacy video sources. |
| Operating Temperature | −40°C to +105°C - qualified for under-hood or dashboard-mounted automotive applications per AEC-Q100 requirements. |
| Power Supply | DVDDIO = 2.97–3.63 V; AVDD/DVDD/PVDD/MVDD = 1.71–1.89 V - supports low-noise, tightly regulated 1.8 V and 3.3 V rail architectures common in automotive ECUs. |
| Package | 32-lead, 5 mm × 5 mm LFCSP - RoHS-compliant surface-mount package with exposed thermal pad for enhanced heat dissipation in compact modules. |
Pinout & Package
Package: 32-lead, 5 mm × 5 mm, RoHS-compliant LFCSP with exposed thermal pad connected to DGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1–AIN8 | Analog Video Input | Differential/pseudo-differential/single-ended CVBS/Y/C/YPrPb inputs - eight independent channels enable simultaneous multi-source decoding without external switching. |
| XTALP / XTALN | Clock Input | 28.63636 MHz crystal oscillator interface - provides precise reference for internal PLL and pixel clock generation required for MIPI CSI-2 timing compliance. |
| D0P / D0N / CLKP / CLKN | MIPI CSI-2 Output | Differential data and clock lanes - deliver 8-bit YCrCb 4:2:2 video stream at up to 216 Mbps with HS/LP mode transitions per MIPI specification. |
| GPO0–GPO2 | General-Purpose Output | Configurable digital outputs - support system-level control signaling such as camera select, sync pulse generation, or status indication. |
| SCLK / SDATA | I²C Interface | 2-wire serial programming port (400 kHz max) - enables register configuration, format detection status reads, and interrupt handling during runtime. |
| PWRDWN | Power Control | Active-low hardware power-down - reduces total supply current to ≤4.5 μA (MVDD) and ≤73 μA (DVDDIO), critical for low-quiescent automotive subsystems. |
Key Features
| Feature | Design Value |
|---|---|
| 8-channel analog input architecture | Eliminates need for external analog switches in multi-camera systems, reducing BOM count and signal path degradation. |
| Integrated short-to-battery (STB) diagnostics | Enables real-time fault detection on two video inputs - critical for ASIL-B–compliant automotive vision systems requiring functional safety monitoring. |
| Adaptive Digital Line Length Tracking (ADLLT) | Provides mini-time base correction (TBC) without external memory, stabilizing output timing against horizontal jitter in unstable analog sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SDTV video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7282-M | Same 8-input architecture and MIPI CSI-2 output, but adds embedded VBI data slicer with closed captioning support and enhanced Rovi detection. | Better suited for broadcast-content-aware systems requiring CC/EIA-608 parsing and advanced copy protection handling. | Select ADV7282-M when VBI metadata extraction or extended Macrovision version compatibility is required. |
| MAX9526 | 10-bit SD decoder with 4-channel input and BT.656 parallel output; no MIPI interface, no STB diagnostics, lower temperature grade (−40°C to +85°C). | Targeted at cost-sensitive consumer media players where parallel interface and non-automotive thermal range are acceptable. | Choose MAX9526 only for non-automotive, non-MIPI designs where BOM cost outweighs interface flexibility and functional safety features. |
Compared with ADV7281WBCPZ-MA, ADV7282-M extends VBI and copy protection capabilities while maintaining pin and software compatibility, whereas MAX9526 offers lower integration and thermal performance-making it unsuitable for automotive deployment despite similar decoding function.

FAQ
What video standards does the ADV7281WBCPZ-MA support?
The ADV7281WBCPZ-MA supports worldwide NTSC, PAL, and SECAM analog video standards across composite (CVBS), S-video (Y/C), and component (YPrPb) formats. It performs automatic format detection without external configuration, and its 10-bit ADC with 4× oversampling ensures accurate digitization regardless of standard. The ADV7281WBCPZ-MA maintains specified differential phase (<0.9°) and gain (<0.5%) accuracy for all supported standards.
Does the ADV7281WBCPZ-MA support differential video inputs?
Yes, the ADV7281WBCPZ-MA supports fully differential, pseudo-differential, and single-ended analog video inputs on all eight AIN channels. Its analog front end includes on-chip antialiasing filters and delivers excellent common-mode noise rejection (>73 dB CMRR with matched external resistors). This makes the ADV7281WBCPZ-MA ideal for noisy automotive environments where differential signaling improves immunity to EMI.
What is the purpose of the GPO0–GPO2 pins on the ADV7281WBCPZ-MA?
The GPO0, GPO1, and GPO2 pins on the ADV7281WBCPZ-MA are general-purpose outputs configurable via I²C registers to drive external logic, LEDs, or enable signals. They support system-level functions such as camera selection synchronization, interrupt acknowledgment, or status indication in multi-camera automotive systems. Unlike the ADV7281 and ADV7281-M variants, only the ADV7281WBCPZ-MA provides three GPOs-enhancing its flexibility in complex vision subsystems.
How does the ADV7281WBCPZ-MA handle power-down mode?
The ADV7281WBCPZ-MA enters hardware power-down mode when the PWRDWN pin is driven low, reducing total supply current to ≤73 μA on DVDDIO and ≤4.5 μA on MVDD. All internal circuitry-including MIPI transmitter, ADC, and PLL-is disabled while retaining register state if DVDD remains active. This ultra-low quiescent mode meets stringent automotive subsystem sleep-current requirements, and the ADV7281WBCPZ-MA resumes full operation within microseconds upon PWRDWN deassertion.
Is the ADV7281WBCPZ-MA pin-compatible with other members of the ADV7281 family?
No, the ADV7281WBCPZ-MA is not pin-compatible with the ADV7281 or ADV7281-M. While all share the same 32-lead LFCSP package footprint, the ADV7281WBCPZ-MA replaces DIAG1/DIAG2 pins with AIN7/AIN8 and adds GPO0–GPO2, resulting in different pin assignments. Its pinout is identical only to the ADV7281-MA variant. Therefore, board layout must be designed specifically for ADV7281WBCPZ-MA or ADV7281-MA, and the ADV7281WBCPZ-MA cannot serve as a drop-in replacement for earlier family members.
