ADV7800BSTZ-150

Overview

The ADV7800BSTZ-150 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 digitizes RGB graphics with a maximum pixel clock rate of 150 MHz. It includes a 3D comb filter, 3D digital noise reduction, advanced time base correction, and interlaced-to-progressive conversion. A 24-bit digital input port supports DVI/HDMI data.

Feature Summary

• Integrates four 10-bit analog-to-digital converters for high dynamic range processing.
• Features an adaptive 3D comb filter and 3D digital noise reduction for superior signal quality.
• Supports simultaneous interlaced and progressive parallel output for multiple video standards.
• Includes a 24-bit digital input port compatible with DVI and HDMI receiver interfaces.

Applications

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

Procurement Notes

Verify the specific suffix 'BSTZ-150' against official Analog Devices documentation to confirm package type, temperature grade, and speed bin. Ensure compatibility with required external SDRAM memory configurations and power supply voltages (DVDD, AVDD) during system design. Confirm RoHS compliance status through current datasheets.

Selection Notes

Select this component when designing systems requiring simultaneous SDTV decoding and HDTV component processing. The 150 MHz speed grade is necessary for full-resolution RGB graphics digitization. Evaluate the need for integrated SCART functionality and overlay capabilities. Consider the external memory requirements for DDR/SDR SDRAM interfaces when planning board layout.

Part Context

The ADV7800 belongs to Analog Devices' family of multiformat video decoders and digitizers. It combines standard definition processing with component processor capabilities in a single chip. This integration reduces bill-of-materials complexity by eliminating the need for separate decoders and digitizers in hybrid display applications.

Replacement Considerations

Consult official Analog Devices documentation for confirmed substitute part numbers. Verify functional equivalence regarding pinout, voltage levels, and supported video standards before implementation.
