ADV7182ABCPZ

Overview

The ADV7182ABCPZ is a multiformat SDTV video decoder in a 32-lead LFCSP package. It features one 10-bit ADC with 4× oversampling for CVBS, S-Video, and YPrPb inputs. The device supports NTSC, PAL, and SECAM standards with automatic detection. It outputs 8-bit ITU-R BT.656 YCrCb 4:2:2 data via an I²C interface. Operating voltages include 1.8 V for analog/digital cores and 1.62 V to 3.63 V for I/O. It operates from -40°C to +85°C.

Feature Summary

• Supports worldwide NTSC, PAL, and SECAM color demodulation with automatic standard detection.
• Features four analog video input channels with on-chip antialiasing filters and differential/single-ended support.
• Includes five-line adaptive comb filters and CTI/DNR video enhancement capabilities.
• Integrates AGC, ACE, and Rovi copy protection detection within the digital processing block.

Applications

• Advanced driver assistance systems
• Automotive infotainment units
• DVRs for video security

Procurement Notes

Verify that the specific suffix 'BCPZ' corresponds to the industrial temperature grade (-40°C to +85°C) rather than the automotive grade (-40°C to +105°C). Confirm the package type is LFCSP-32 and ensure RoHS compliance matches project requirements. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a single-chip solution is required for converting analog baseband video into digital ITU-R BT.656 streams. It is suitable for applications needing direct connection of differential or single-ended CVBS signals without external amplifiers. Consider its low power consumption and integrated signal processing features for space-constrained designs.

Part Context

The ADV7182A series includes variants like the ADV7182 and ADV7182A, which share pinouts and software compatibility. The ADV7182ABCPZ represents the industrial-grade version of this versatile decoder. It belongs to Analog Devices' portfolio of video processing ICs designed for consumer and automotive multimedia applications.

Replacement Considerations

The ADV7182AWBCPZ-RL is a listed alternative model. Verify if the 'W' suffix indicates a different temperature rating or packaging configuration before substitution.

FAQ

Does the ADV7182ABCPZ support differential video inputs?

Yes, the device features a differential-to-single-ended converter that accommodates direct connection of differential, pseudo-differential, or single-ended CVBS signals.

What is the maximum I2C clock frequency?

The maximum serial clock (SCLK) frequency for the I2C port is 400 kHz.
