Product details
Overview
ADV7280WBCPZ-RL from Analog Devices is a 10-bit, 4× oversampled SDTV video decoder with integrated deinterlacer and I2P conversion, supporting NTSC/PAL/SECAM autodetection across CVBS, Y/C, and YPrPb inputs. It outputs 8-bit ITU-R BT.656 YCrCb 4:2:2 video data with line-locked LLC clock and delivers mini-TBC functionality via ADLLT and enhanced FIFO management for automotive infotainment and DVR systems.
For engineers reviewing the ADV7280WBCPZ-RL datasheet, ADV7280WBCPZ-RL pinout, ADV7280WBCPZ-RL application, or ADV7280WBCPZ-RL equivalent, key selection criteria include its 32-lead LFCSP package, −40°C to +105°C automotive qualification, 28.63636 MHz crystal interface, 4-channel analog input support, and 8-bit BT.656 output timing compliance.
Technical Context
The ADV7280WBCPZ-RL implements a single 10-bit ADC with 4× oversampling per channel for CVBS/Y/C/YPrPb modes, paired with a 5-line adaptive 2D comb filter and CTI enhancement. Its analog front end includes on-chip antialiasing filters and supports up to 1.47 V common-mode input range with excellent CMRR (73 dB) using external 0.1% resistor matching.
Signal processing includes adaptive digital line length tracking (ADLLT), automatic gain control with adaptive peak white mode, and Rovi copy protection detection. The I2P converter operates without external memory, using edge-adaptive algorithms to minimize artifacts on low-angle lines while maintaining full-field progressive output at 27 MHz LLC clock rate.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SDTV video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7281WBCPZ-RL | Same pinout and package; adds MIPI CSI-2 output alongside BT.656 - requires MVDD supply and CLKN/D0N routing. | Targeted at mobile processors with MIPI receivers; not drop-in for BT.656-only hosts. | Select ADV7281WBCPZ-RL only if migrating to MIPI interface and redesigning PCB layout for differential pairs. |
| MAX9526ETX+T | 10-bit decoder with BT.656 output but no integrated I2P; requires external memory for deinterlacing and lacks ADLLT/mini-TBC. | Suitable for cost-sensitive DVRs where motion artifacts are acceptable and external frame buffer is available. | Choose MAX9526ETX+T when minimizing BOM cost outweighs need for real-time deinterlacing and timing stabilization. |
Compared with ADV7280WBCPZ-RL, ADV7281WBCPZ-RL adds MIPI flexibility at the cost of increased layout complexity, while MAX9526ETX+T reduces integration to lower cost but sacrifices autonomous I2P and TBC capabilities essential for automotive and premium DVR use cases.

FAQ
What video standards does the ADV7280WBCPZ-RL support?
The ADV7280WBCPZ-RL supports worldwide NTSC, PAL, and SECAM analog video standards with automatic detection and seamless switching. It processes composite (CVBS), S-Video (Y/C), and component (YPrPb) inputs, delivering decoded 8-bit YCrCb 4:2:2 data over ITU-R BT.656 interface. All standard definition formats-including NTSC M, PAL B/G/H/I/D/K/L, and SECAM L/L'-are handled natively by the ADV7280WBCPZ-RL without firmware configuration.
Does the ADV7280WBCPZ-RL require an external crystal?
Yes, the ADV7280WBCPZ-RL requires a 28.63636 MHz fundamental crystal connected between XTALP and XTALN pins for precise subcarrier lock and stable LLC clock generation. Alternatively, a 1.8 V CMOS oscillator may drive XTALN directly, with XTALP left unconnected. The crystal's ±50 ppm stability is mandatory for reliable NTSC/PAL color demodulation and timing accuracy in the ADV7280WBCPZ-RL.
What is the function of the VS/FIELD/SFL pin on the ADV7280WBCPZ-RL?
The VS/FIELD/SFL pin on the ADV7280WBCPZ-RL is a multifunction output configurable via I2C register: it can deliver vertical sync (VS), field sync (FIELD), or subcarrier frequency lock (SFL) signal. In SFL mode, it outputs a serial stream used to synchronize external Analog Devices encoders. This triple-mode capability allows flexible timing integration in systems using the ADV7280WBCPZ-RL for both display and encode-loop applications.
How does the ADV7280WBCPZ-RL handle power management?
ADV7280WBCPZ-RL supports hardware-controlled power-down via the active-low PWRDWN pin, reducing total supply current to ≤84 µA (DVDDIO), ≤420 µA (DVDD), ≤46 µA (PVDD), and ≤0.2 µA (AVDD). It also features programmable sleep modes through I2C, enabling dynamic power scaling during inactive video periods. All power domains retain state during brief power-down cycles, allowing rapid resumption of decoding without full reinitialization of the ADV7280WBCPZ-RL.
Is the ADV7280WBCPZ-RL pin-compatible with the ADV7280-M variant?
No, the ADV7280WBCPZ-RL is not pin-compatible with the ADV7280-M. While both share the same 32-lead LFCSP package, the ADV7280WBCPZ-RL uses P0–P7, HS, VS/FIELD/SFL, and LLC for BT.656 output, whereas the ADV7280-M replaces those with MIPI CSI-2 signals (D0P/D0N/CLKP/CLKN) and adds GPO0–GPO2 and MVDD. Pin functions differ significantly; direct substitution would require PCB redesign and firmware adaptation for the ADV7280WBCPZ-RL.
