Analog Devices Inc. ADV7283BCPZ

Overview

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

For engineers reviewing the ADV7283BCPZ datasheet, ADV7283BCPZ pinout, ADV7283BCPZ application, or ADV7283BCPZ equivalent, key selection considerations include its 27 MHz LLC pixel clock, 4 V common-mode input range, Rovi® copy protection detection, 75 mA typical analog supply current in YPrPb mode, and LFCSP-32 package compatibility with high-density automotive PCB layouts.

Technical Context

The ADV7283BCPZ 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), adaptive digital line length tracking (ADLLT™) for VCR/tuner signal stabilization, and on-chip clamping with fine/peak-white AGC. Its analog front end accepts fully differential, pseudo-differential, or single-ended CVBS signals using external resistor networks.

It implements a hardware-based interlaced-to-progressive (I2P) converter without external memory, outputs progressive 8-bit BT.656 data synchronized to a line-locked LLC clock, and includes a full VBI slicer supporting WST, CCAP, CGMS, and WSS - all programmable via I2C at up to 400 kHz.

Key Specifications

Pinout & Package

ADV7283BCPZ is housed in a 32-lead, 5 mm × 5 mm, RoHS-compliant LFCSP package with exposed thermal pad. The package supports high thermal conductivity mounting to PCB ground planes (θ_JA = 32.5°C/W, θ_JC = 2.3°C/W) and requires DGND pins and EPAD to be connected to a common ground plane.

FAQ

What video standards does the ADV7283BCPZ support?

The ADV7283BCPZ supports worldwide NTSC (J/M/4.43), PAL (B/D/G/H/I/M/N/Nc/60), and SECAM (B/D/G/K/L) standards in composite (CVBS), S-Video (Y/C), and component (YPrPb) formats. It performs automatic standard detection and adapts processing parameters accordingly - no manual configuration is required for format switching.

Does the ADV7283BCPZ require an external crystal?

Yes, the ADV7283BCPZ requires a 28.63636 MHz fundamental crystal connected between XTALP and XTALN pins to generate internal clocks for ADC sampling (57.27/114/172 MHz) and system timing. An external 1.8 V oscillator may be used instead, fed into XTALN with XTALP left unconnected.

How does the ADV7283BCPZ handle differential CVBS inputs?

The ADV7283BCPZ accepts fully differential CVBS inputs across AIN1–AIN6 with up to 4 V common-mode range using external resistor dividers. Its analog front end provides >73 dB common-mode rejection (with 0.1% resistors), enabling reliable operation in electrically noisy automotive environments with ground potential differences.

Can the ADV7283BCPZ output progressive video without external memory?

Yes, the ADV7283BCPZ integrates a hardware-based interlaced-to-progressive (I2P) converter that operates without external memory. It uses on-chip FIFOs and ADLLT processing to generate stable progressive BT.656 output - reducing system cost, latency, and PCB footprint compared to solutions requiring DRAM or SRAM buffers.

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

The INTRQ pin on the ADV7283BCPZ is an active-low, open-drain interrupt output that signals events such as video lock loss, standard change (e.g., NTSC → PAL), VBI data ready, or Rovi® detection. It allows firmware to respond asynchronously without continuous I2C polling, improving system responsiveness and reducing processor load.
