Product details
Overview
ADV7401KSTZ-140 from Analog Devices is a 10-bit integrated multiformat SDTV/HDTV video decoder and RGB graphics digitizer, supporting analog input sampling up to 140 MHz, NTSC/PAL/SECAM decoding, 720p/1080i HDTV component processing, and digitization of RGB graphics up to 1280 × 1024 @ 75 Hz. It serves as the front-end video acquisition IC in high-definition television receivers and set-top boxes.
For engineers reviewing the ADV7401KSTZ-140 datasheet, ADV7401KSTZ-140 pinout, ADV7401KSTZ-140 application, or ADV7401KSTZ-140 equivalent, key selection considerations include its 140 MHz speed grade, dual-standard definition/component processor architecture, 12-channel analog mux, 24-bit digital input port for DVI/HDMI Rx interfacing, and industrial-grade thermal performance with 0°C to +70°C operating range.
Technical Context
The ADV7401KSTZ-140 integrates two independent processing engines: a Standard Definition Processor (SDP) handling CVBS/S-video with adaptive 2D comb filtering and automatic PAL/NTSC/SECAM detection, and a Component Processor (CP) supporting 525p/625p/720p/1080i formats and RGB graphics digitization. Both sections share four 10-bit ADCs clocked by a line-locked LLC1 output ranging from 12.825 MHz to 140 MHz.
It features a 24-bit digital input port for receiving pixel data from HDMI/DVI receiver ICs, programmable interrupt generation via the INT pin, VBI data slicing for teletext and closed captioning, and SCART fast-blank overlay control between CVBS and RGB signals using the FB pin.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7403KSTZ | Same 10-bit architecture but rated for 110 MHz max sampling; lacks 140 MHz SXGA support and reduced VBI feature set. | Targeted at cost-sensitive 720p-only designs without requirement for 1280×1024 graphics digitization. | Select ADV7403KSTZ only if 140 MHz capability and full VBI slicing are not required. |
| MAX9526ETM+ | 8-bit decoder with 40 MHz max sampling; no component processor, no DDR output, no VBI slicing. | Intended for basic SDTV applications like portable media players or low-cost monitors. | Not suitable as functional replacement; use only in new SD-only designs where HDTV and graphics digitization are excluded. |
Compared with ADV7403KSTZ and MAX9526ETM+, the ADV7401KSTZ-140 uniquely delivers 140 MHz sampling for SXGA graphics, dual SDP/CP processing, and full VBI data recovery-making it irreplaceable in high-end HDTV and STB platforms requiring multiformat flexibility and broadcast compliance.

FAQ
What video standards does the ADV7401KSTZ-140 support?
The ADV7401KSTZ-140 supports NTSC (J/M/4.43), PAL (B/D/G/H/I/M/N/60), and SECAM (B/D/G/K/L) via composite and S-video inputs, plus component formats including 525i/625i/525p/625p/720p/1080i. It also digitizes RGB graphics up to 1280 × 1024 @ 75 Hz. All standard detection and decoding functions are implemented in hardware within the ADV7401KSTZ-140's SDP and CP cores.
Does the ADV7401KSTZ-140 include Macrovision copy protection detection?
Yes, the ADV7401KSTZ-140 includes certified Macrovision copy protection detection on both composite and S-video inputs across all supported PAL/NTSC/SECAM formats. This functionality is implemented in the SDP section and requires no external components-detection status is reported via register bits accessible through the ADV7401KSTZ-140's I²C control port.
What is the maximum pixel clock frequency supported by the ADV7401KSTZ-140?
The ADV7401KSTZ-140 supports a maximum LLC1 pixel clock output frequency of 140 MHz, which is explicitly specified for this speed grade in the ordering guide and electrical characteristics tables. This enables digitization of SXGA (1280 × 1024 @ 75 Hz) RGB graphics and 1080i HDTV component video without undersampling or interpolation artifacts.
Can the ADV7401KSTZ-140 accept digital video input from an HDMI receiver IC?
Yes, the ADV7401KSTZ-140 includes a dedicated 24-bit digital input port (pins P0–P23, DE_IN, HS_IN/CS_IN, VS_IN, DCLK_IN) that accepts pixel data from HDMI or DVI receiver ICs. This port operates in 24-bit RGB mode and supports embedded sync timing, allowing direct connection without external FIFOs or glue logic in the ADV7401KSTZ-140-based design.
What is the operating temperature range for the ADV7401KSTZ-140?
The ADV7401KSTZ-140 is specified for operation from 0°C to +70°C, as confirmed in Table 1 footnote 2 and Table 2 footnote 2 of the Rev. B datasheet. This commercial temperature grade distinguishes it from the industrial-grade ADV7401 variants rated for −40°C to +85°C, and aligns with typical thermal envelopes of consumer HDTV and STB chassis.
