Analog Devices Inc. ADV7182BCPZ-RL

Overview

ADV7182BCPZ-RL from Analog Devices is a 10-bit SDTV video decoder IC that converts NTSC/PAL/SECAM composite, S-Video, and YPrPb analog video inputs into an 8-bit ITU-R BT.656 4:2:2 digital output stream. It features a single 10-bit ADC with 4× oversampling per channel, five-line adaptive comb filtering, Rovi Macrovision copy protection detection, and supports differential CVBS input with up to 4 V common-mode range - enabling robust operation in automotive infotainment systems.

For engineers reviewing the ADV7182BCPZ-RL datasheet, ADV7182BCPZ-RL pinout, ADV7182BCPZ-RL application, or ADV7182BCPZ-RL equivalent, this device is selected for designs requiring autodetection of global analog video standards, low-power SD decoding with integrated VBI data slicing (teletext/WST), and high CMR (>75 dB) in space-constrained LFCSP packages.

Technical Context

The ADV7182BCPZ-RL integrates a fully differential analog front end with four analog input channels, on-chip antialiasing filters, and a 10-bit ADC clocked at 57.27 MHz (CVBS), 114 MHz (Y/C), or 172 MHz (YPrPb). Its standard definition processor implements ADLLT™ for adaptive line-length tracking and patented 2D comb filtering optimized for composite signal separation.

It delivers synchronized 8-bit pixel data (P7–P0) with HS, VS/FIELD, and LLC timing outputs, while supporting I²C-compatible MPU control, automatic gain control with adaptive peak white mode, and programmable power-down modes drawing as low as 0.15 µA on AVDD.

FAQ

What video standards does the ADV7182BCPZ-RL support?

The ADV7182BCPZ-RL supports worldwide NTSC (M/J/4.43), PAL (B/D/G/H/I/60/M/N/Nc), and SECAM (B/D/G/K/L) standards in composite, S-Video, and YPrPb formats. It performs automatic detection and seamless switching between these standards without host intervention, as confirmed in the Rev. C datasheet Section "Overview of the Standard Definition Processor" and Table 3 autodetection timing.

Does the ADV7182BCPZ-RL support differential CVBS input?

Yes, the ADV7182BCPZ-RL supports fully differential, pseudo-differential, and single-ended CVBS inputs. Its analog front end is explicitly designed for differential operation, enabling up to 4 V common-mode input range and achieving 75 dB common-mode rejection when used with matched external resistors - details are specified in the General Description and Table 3 of the Rev. C datasheet.

What is the function of the INTRQ pin on the ADV7182BCPZ-RL?

The INTRQ pin on the ADV7182BCPZ-RL is an active-low, open-drain interrupt request output that signals events including loss of video lock, detected format change, Macrovision trigger, or VBI data ready. It allows the host processor to respond asynchronously rather than polling registers, improving system efficiency - described in Table 8 (Pin Function Descriptions) and Section "Global Status Register" of the Rev. C datasheet.

Can the ADV7182BCPZ-RL operate from a single 1.8 V supply?

Yes, the ADV7182BCPZ-RL supports single 1.8 V operation for AVDD, DVDD, PVDD, and DVDDIO supplies, as stated in the Features section and Electrical Characteristics table (Table 2). This simplifies power design in space-constrained applications like portable media players, though DVDDIO may be raised to 3.3 V for interfacing with higher-voltage hosts.

What package type is used for the ADV7182BCPZ-RL?

The ADV7182BCPZ-RL uses a 32-lead, 5 mm × 5 mm, RoHS-compliant LFCSP (Lead Frame Chip Scale Package) with exposed thermal pad. This package is specified in the Features section, Outline Dimensions (page 96), and Ordering Guide of the Rev. C datasheet - confirming mechanical compatibility and thermal performance (θJA = 32.5°C/W) for automotive and industrial use.
