ADV7401KSTZ-140

Overview

The ADV7401KSTZ-140 is a high-quality, single-chip multiformat video decoder and graphics digitizer manufactured by Analog Devices. It features four 10-bit ADCs sampling up to 140 MHz, supporting NTSC, PAL, SECAM, and HDTV component standards. The device includes a 12-channel analog input multiplexer, internal antialias filters, and a 24-bit digital input port for DVI/HDMI sources. It provides RGB graphics digitization up to SXGA resolution and outputs pixel data via a 12-bit DDR or 8-bit SDR interface.

Feature Summary

• Supports simultaneous processing of composite/S-video and standard definition RGB signals with SCART fast blank overlay functionality.
• Integrates a Standard Definition Processor (SDP) and Component Processor (CP) for comprehensive signal decoding and color-space conversion.
• Includes a VBI data slicer capable of extracting teletext, closed captioning, and CGMS data from the vertical blanking interval.
• Features a 3x3 programmable color-space conversion matrix for flexible YCrCb and RGB format translation.

Applications

• LCD/DLP rear projection HDTVs
• HDTV set-top boxes with PVR capabilities
• Hard-disk-based video recorders
• Multiformat scan converters

Procurement Notes

Verify that the specific suffix -140 corresponds to the 140 MHz speed grade variant when sourcing. Confirm the operating temperature range requirements, as this specific grade may differ from the industrial range (-40°C to +85°C) offered by other variants in the ADV7401 family. Ensure I2C address configurations align with system design constraints before finalizing procurement.

Selection Notes

Select this model specifically for applications requiring a maximum sampling rate of 140 MHz to support SXGA graphics digitization. Compare against lower-speed variants if only SDTV or lower-resolution HD formats are required, as those may offer different thermal or power characteristics. Verify compatibility with the target pixel output interface (DDR vs. SDR) and ensure the host processor supports the required data rates.

Part Context

This component belongs to the ADV7401 series of integrated video decoders. It serves as a bridge between analog video sources and digital display processors. The device consolidates multiple functions typically found in discrete solutions, including decoding, digitization, and timing recovery, into a single LQFP-100 package.

Replacement Considerations

Public confirmed substitute part numbers: ADV7401BSTZ-110, ADV7401BSTZ-80.
