ADV7182WBCPZ-RL

Overview

The ADV7182WBCPZ-RL is a 10-bit SDTV video decoder with differential inputs, converting analog baseband signals to 8-bit ITU-R BT.656 YCrCb 4:2:2 data. It supports NTSC, PAL, and SECAM standards via CVBS, Y/C, and YPrPb inputs. The device features a single 10-bit ADC with 4× oversampling, five-line adaptive comb filters, and an integrated TBC using ADLLT. Operating on a single 1.8 V supply, it includes AGC, ACE, and Macrovision detection within a 32-lead LFCSP package.

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 for composite, S-Video, and component formats.
• Includes five-line adaptive comb filters and CTI/DNR video enhancement for superior image quality.
• Provides TBC functionality through adaptive digital line length tracking and enhanced FIFO management.

Applications
