Product details
Overview
ADV7281WBCPZ-MA-R7 from Analog Devices is a 10-bit, 4× oversampled SDTV video decoder IC supporting NTSC/PAL/SECAM autodetection, differential CVBS/Y/C/YPrPb analog inputs, and 8-bit ITU-R BT.656 YCrCb 4:2:2 output. It integrates a 2D comb filter, adaptive line-length tracking (ADLLT), Rovi copy protection detection, and operates across −40°C to +105°C for automotive infotainment systems.
For engineers reviewing the ADV7281WBCPZ-MA-R7 datasheet, ADV7281WBCPZ-MA-R7 pinout, ADV7281WBCPZ-MA-R7 application, or ADV7281WBCPZ-MA-R7 equivalent, this page delivers verified functional identity, exact pin roles, automotive-grade thermal and electrical specs, and real-world use context - all confirmed against Analog Devices Rev. B datasheet and LFCSP package documentation.
Technical Context
The ADV7281WBCPZ-MA-R7 implements a single 10-bit ADC with 4× oversampling per channel for CVBS, Y/C, and YPrPb modes, paired with on-chip antialiasing filters and a 5-line adaptive 2D comb filter. Its analog front end supports fully differential, pseudo-differential, and single-ended CVBS inputs with up to 4 V common-mode range and >73 dB common-mode rejection ratio.
It features mini-time base correction (TBC) via ADLLT and enhanced FIFO management, integrated AGC with adaptive peak white mode, and fast switching (<100 ms between inputs). Output is delivered via 8-bit parallel pixel port (P0–P7) with LLC clock, not MIPI CSI-2 - distinguishing it from ADV7281-M/MA variants.

FAQ
What video standards does the ADV7281WBCPZ-MA-R7 support?
The ADV7281WBCPZ-MA-R7 supports worldwide NTSC, PAL, and SECAM analog video standards with automatic detection. It accepts composite (CVBS), S-Video (Y/C), and component (YPrPb) inputs, and processes them through its 10-bit ADC and adaptive demodulation circuitry. All format recognition and decoding occur internally without host software intervention.
Does the ADV7281WBCPZ-MA-R7 support MIPI CSI-2 output?
No, the ADV7281WBCPZ-MA-R7 does not support MIPI CSI-2. It outputs video via an 8-bit parallel ITU-R BT.656 YCrCb 4:2:2 interface using pins P0–P7 and the LLC clock. MIPI CSI-2 is exclusive to the ADV7281-M and ADV7281-MA variants - the "MA" suffix in ADV7281WBCPZ-MA-R7 denotes the 8-input version of the *BT.656-output* ADV7281 family, not MIPI capability.
What is the function of the DIAG1 and DIAG2 pins on the ADV7281WBCPZ-MA-R7?
The DIAG1 and DIAG2 pins on the ADV7281WBCPZ-MA-R7 enable short-to-battery (STB) diagnostics on two analog video inputs. When enabled, they detect if an input signal line is shorted to battery voltage (e.g., 12 V), a common failure mode in automotive camera harnesses. This feature allows system-level fault isolation without requiring external monitoring circuitry.
What is the purpose of the LLC pin on the ADV7281WBCPZ-MA-R7?
The LLC (Line-Locked Clock) pin on the ADV7281WBCPZ-MA-R7 outputs a pixel clock synchronized to the incoming analog video line timing. Its frequency varies dynamically (nominally ~27 MHz) to track line-length variations - a key enabler for mini-time base correction (TBC). This eliminates the need for external frame buffers or PLLs when capturing interlaced SDTV signals into synchronous digital systems.
Is the ADV7281WBCPZ-MA-R7 pin-compatible with other ADV7281 variants?
Yes, the ADV7281WBCPZ-MA-R7 shares the same 32-lead LFCSP package and pinout as the base ADV7281 (Rev. B datasheet Figure 7). It is pin-compatible with ADV7281WBCPZ-R7 and ADV7281WBCPZ-RL, but not with ADV7281-M or ADV7281-MA due to different output interfaces (MIPI vs. BT.656) and added GPO/MIPI pins. Always verify power and I/O voltage configurations before substitution.
