Analog Devices Inc. ADV7280KCPZ-RL

Overview

ADV7280KCPZ-RL from Analog Devices is a 10-bit, 4× oversampled SDTV video decoder with integrated deinterlacer and 8-bit ITU-R BT.656 output. It supports worldwide NTSC/PAL/SECAM standards across CVBS, Y/C, and YPrPb inputs, delivers mini-TBC functionality via ADLLT and FIFO management, and operates from −40°C to +105°C for automotive infotainment systems.

For engineers reviewing the ADV7280KCPZ-RL datasheet, ADV7280KCPZ-RL pinout, ADV7280KCPZ-RL application, or ADV7280KCPZ-RL equivalent, key selection considerations include its 4-channel analog input capability, 27 MHz line-locked LLC clock, I²C programmability, 32-lead 5 mm × 5 mm LFCSP package, and qualification for automotive AEC-Q100 Grade 2 environments.

Technical Context

The ADV7280KCPZ-RL implements a fully integrated analog front end with on-chip antialiasing filters and a 10-bit ADC per channel, enabling simultaneous digitization of up to four single-ended analog video sources. Its standard definition processor (SDP) performs NTSC/PAL/SECAM autodetection, 5-line adaptive 2D comb filtering, and Rovi copy protection detection without external memory.

It integrates an interlaced-to-progressive (I2P) converter using edge-adaptive algorithms and provides mini-time base correction via Adaptive Digital Line Length Tracking (ADLLT) and enhanced FIFO management. Output is delivered as an 8-bit YCrCb 4:2:2 stream compliant with ITU-R BT.656, synchronized by HS, VS/FIELD/SFL, and LLC signals.

Key Specifications

Pinout & Package

ADV7280KCPZ-RL uses a 32-lead, 5 mm × 5 mm, RoHS-compliant LFCSP package with exposed thermal pad requiring connection to DGND. Pin functions are validated per Analog Devices' Rev. A datasheet (pages 11–12).

Equivalent & Alternatives

The following parts are listed as comparable options for similar SDTV video decoder applications.

Compared with ADV7281KCPZ-RL, the ADV7280KCPZ-RL offers identical automotive qualification and BT.656 output but trades input count for smaller footprint and lower power. Against MAX9526ETX+T, it delivers superior timing stability, integrated deinterlacing, and full AEC-Q100 compliance-justifying its use in safety-critical automotive vision systems.

FAQ

What video standards does the ADV7280KCPZ-RL support?

The ADV7280KCPZ-RL supports worldwide NTSC, PAL, and SECAM analog video standards with automatic detection and seamless switching. It accepts composite (CVBS), S-Video (Y/C), and component (YPrPb) inputs, and processes them through its 10-bit ADC and standard definition processor. The ADV7280KCPZ-RL handles all major regional variants including NTSC-M, PAL-B/G/H/I/D/K, and SECAM-L/L' without firmware intervention.

Does the ADV7280KCPZ-RL require an external crystal?

Yes, the ADV7280KCPZ-RL requires a 28.63636 MHz fundamental-mode crystal connected between XTALP and XTALN pins. This crystal drives the internal PLL to generate precise video timing clocks. An external 1.8 V oscillator may alternatively feed XTALN, but the crystal solution is preferred for jitter-sensitive automotive applications. The ADV7280KCPZ-RL does not operate without this timing source.

What is the function of the VS/FIELD/SFL pin on the ADV7280KCPZ-RL?

The VS/FIELD/SFL pin on the ADV7280KCPZ-RL is a multifunction output configurable via I²C registers. It can deliver vertical synchronization pulses, field identification signals for interlaced formats, or a serial subcarrier frequency lock stream used to synchronize with Analog Devices video encoders. Its behavior is determined by register settings and cannot be changed dynamically without reconfiguration.

Can the ADV7280KCPZ-RL decode VBI data such as closed captions?

Yes, the ADV7280KCPZ-RL includes a full-featured vertical blanking interval (VBI) data slicer capable of extracting closed caption (Line 21), teletext, WSS, and other standard VBI payloads. This functionality is enabled and configured through I²C registers, and sliced data is accessible via dedicated status flags and interrupt signaling on the INTRQ pin.

Is the ADV7280KCPZ-RL pin-compatible with the ADV7280-M variant?

No, the ADV7280KCPZ-RL is not pin-compatible with the ADV7280-M. While both share the same 32-lead LFCSP package, their pinouts differ significantly: the ADV7280KCPZ-RL uses P0–P7, HS, VS/FIELD/SFL, and LLC for BT.656 output, whereas the ADV7280-M substitutes those with MIPI CSI-2 lanes (D0P/D0N/CLKP/CLKN) and GPOs. PCB layout and firmware must be redesigned for migration.
