ADV7800BSTZ-80

Overview

The ADV7800BSTZ-80 is a high-quality, single-chip multiformat video decoder and graphics digitizer featuring four 10-bit ADCs. It supports NTSC, PAL, SECAM, and component standards including 525i/625i, 525p/625p, 720p, 1080i, and 1080p. The device includes a 12-channel analog input mux, 3D comb filtering, advanced time base correction, and interlaced-to-progressive conversion. It digitizes RGB graphics up to 150 MHz and features a 24-bit digital input port for DVI/HDMI sources.

Feature Summary

• Integrates four 10-bit ADCs with a 12-channel analog input multiplexer for direct connection of multiple video sources without external switching components.
• Processes standard definition signals using adaptive 3D comb filtering and advanced time base correction with frame synchronization.
• Supports simultaneous processing of composite and RGB signals to enable SCART compatibility and overlay functionality.
• Converts interlaced SD signals to progressive scan formats and handles HDTV component inputs.

Applications

• AV receivers
• LCD HDTVs
• PDP HDTVs
• CRT HDTVs
• HDTV STBs with PVR
