Analog Devices Inc. ADV7283BCPZ-RL

Overview

ADV7283BCPZ-RL from Analog Devices is a 10-bit, 4× oversampled SDTV video decoder IC with integrated deinterlacer (I2P), differential analog inputs, and ITU-R BT.656 8-bit YCrCb 4:2:2 output. It supports worldwide NTSC/PAL/SECAM standards across CVBS, Y/C (S-Video), and YPrPb (component) formats, delivers 5-line adaptive 2D comb filtering, and operates over −40°C to +105°C for automotive infotainment systems.

For engineers reviewing the ADV7283BCPZ-RL datasheet, ADV7283BCPZ-RL pinout, ADV7283BCPZ-RL application, or ADV7283BCPZ-RL equivalent, key selection criteria include its 27 MHz LLC pixel clock, 10-bit ADC resolution with ±0.6 LSB DNL, differential CVBS input support up to 4 V common-mode range, Rovi® copy protection detection, and automotive-grade LFCSP-32 package compatibility.

Technical Context

The ADV7283BCPZ-RL integrates a single 10-bit ADC with 4× oversampling per channel (57.27 MHz for CVBS, 114 MHz for Y/C, 172 MHz for YPrPb), an adaptive digital line length tracking (ADLLT™) engine for time-base correction, and a fully digital I2P converter eliminating external memory. Its analog front end accepts six channels of single-ended, pseudo-differential, or fully differential video inputs with on-chip anti-aliasing filters and clamp circuitry.

It implements a five-line adaptive 2D comb filter with chroma transient improvement (CTI), adaptive contrast enhancement (ACE), and a full VBI slicer supporting WST, CCAP, CGMS, and WSS. Programming occurs via a 400 kHz I2C-compatible interface with ALSB-selectable addresses (0x40/0x42), and power management includes dedicated DVDDIO (1.62–3.63 V), AVDD/DVDD/PVDD (1.71–1.89 V) rails and a dedicated PWRDWN pin.

Key Specifications

Pinout & Package

ADV7283BCPZ-RL is housed in a 32-lead, 5 mm × 5 mm, RoHS-compliant LFCSP package with exposed thermal pad. DGND pins and the EPAD must be connected to a common ground plane per layout guidelines.

FAQ

What video standards does the ADV7283BCPZ-RL support?

The ADV7283BCPZ-RL supports all major worldwide SDTV standards including NTSC (J, M, 4.43), PAL (B, D, G, H, I, M, N, Nc, 60), and SECAM (B, D, G, K, L). It performs automatic detection and seamless switching between these formats on any of its six analog inputs, making ADV7283BCPZ-RL ideal for global automotive and broadcast equipment deployment.

Does ADV7283BCPZ-RL require an external crystal?

Yes, ADV7283BCPZ-RL requires a 28.63636 MHz fundamental crystal connected between XTALP and XTALN pins for normal operation. Alternatively, a 1.8 V CMOS clock oscillator can drive XTALN directly with XTALP left unconnected. The crystal or oscillator provides the master reference for all internal PLLs and timing blocks in ADV7283BCPZ-RL.

How does the ADV7283BCPZ-RL handle differential CVBS inputs?

ADV7283BCPZ-RL accepts fully differential or pseudo-differential CVBS inputs on AIN1–AIN6 using external resistor networks. This configuration enables up to 4 V common-mode input range and superior noise rejection-critical for automotive video links. The internal AFE processes both signal polarities simultaneously, delivering accurate digitization without external amplification in ADV7283BCPZ-RL.

Can ADV7283BCPZ-RL output progressive video without external memory?

Yes, ADV7283BCPZ-RL integrates a hardware-based interlaced-to-progressive (I2P) converter that operates without external memory. Its on-chip FIFO and ADLLT™ algorithm perform real-time line-length tracking and field buffering internally, allowing ADV7283BCPZ-RL to deliver clean progressive BT.656 output directly to display controllers or video processors.

What is the function of the INTRQ pin on ADV7283BCPZ-RL?

The INTRQ pin on ADV7283BCPZ-RL is an open-drain interrupt output that asserts low upon detection of video events including loss of sync, standard change (e.g., NTSC → PAL), VBI data arrival, or Rovi® copy protection activation. This allows host processors to respond asynchronously without continuous register polling, improving system efficiency in ADV7283BCPZ-RL-based designs.
