For engineers reviewing the ADV7402AKSTZ-110 datasheet, ADV7402AKSTZ-110 pinout, ADV7402AKSTZ-110 application, or ADV7402AKSTZ-110 equivalent, this page delivers verified technical context, confirmed pin functions, real-world timing and noise performance metrics, and validated alternative options for multiformat video signal acquisition in broadcast- and consumer-grade display subsystems.

Technical Context

The ADV7402AKSTZ-110 integrates two independent processing engines: a Standard Definition Processor (SDP) handling PAL/NTSC/SECAM via composite or S-video with adaptive 2D 5-line comb filtering, ADLLT™ line-length tracking, and Macrovision® 7.1 detection; and a Component Processor (CP) supporting YPrPb/RGB component formats including 720p, 1080i, and SXGA graphics with programmable 3×3 color space conversion and embedded sync extraction.

It employs three 12-bit 110 MHz Noise Shaped Video® ADCs with 4× oversampling for CVBS/S-video and 1× oversampling for HD formats, delivering 63 dB unweighted SNR (luma ramp), ±0.4° differential phase, and 0.4% differential gain-enabling high-fidelity digitization without external anti-aliasing filters.

FAQ

What video standards does the ADV7402AKSTZ-110 support for composite and S-video inputs?

The ADV7402AKSTZ-110 supports NTSC (J, M, 4.43), PAL (B, D, I, G, H, M, N, Nc 60), and SECAM (B/D/G/K/L) standards in composite (CVBS) and S-video formats. It performs full automatic detection and autoswitching across all worldwide standards, with super adaptive 2D 5-line comb filtering and ADLLT™ for unstable sources like VCRs. The ADV7402AKSTZ-110 also includes certified Macrovision® 7.1 detection for copy-protected content.

Does the ADV7402AKSTZ-110 support RGB graphics digitization, and what is the maximum resolution?

Yes, the ADV7402AKSTZ-110 supports RGB graphics digitization up to 1280×1024@60 Hz (SXGA) using its Component Processor section. It samples at 110 MSPS with a 32-phase DLL for optimal pixel clock alignment, supports automatic/manual clamp and gain control, and provides 24-bit 4:4:4 RGB or converted YCrCb output. The ADV7402AKSTZ-110 also enables arbitrary pixel sampling for non-standard graphics sources.

What are the power supply requirements for the ADV7402AKSTZ-110?

The ADV7402AKSTZ-110 requires four independent supplies: DVDD = 1.65–2.0 V (1.8 V nominal) for the digital core; DVDDIO = 3.0–3.6 V (3.3 V nominal) for digital I/O; AVDD = 3.15–3.45 V (3.3 V nominal) for analog circuitry; and PVDD = 1.65–2.0 V (1.8 V nominal) for the PLL. Total active current draw ranges from 62 mA (graphics mode) to 218 mA (CVBS analog input), with 1.5 mA power-down current.

How does the ADV7402AKSTZ-110 handle timing synchronization for component video inputs?

The ADV7402AKSTZ-110 supports multiple timing modes for component video: embedded sync (SOY/SOG), separate HS/VS/CS inputs, or 4-/5-wire RGB timing. Its Component Processor includes adaptive sync extraction, programmable HS/VS polarity and width, and FIELD/DE output reconfiguration. The ADV7402AKSTZ-110 also features a line-locked clock output (LLC1) from 13.5 MHz to 110 MHz with 45–55% duty cycle, ensuring jitter-free pixel timing for downstream logic.

Can the ADV7402AKSTZ-110 process digital video inputs, and what interfaces are supported?

Yes, the ADV7402AKSTZ-110 includes a 24-bit digital input port supporting raw 10-bit CVBS from digital tuners, 24-bit RGB from DVI/HDMI Rx ICs, and 16-/20-/24-bit YCrCb/RGB from HDMI Rx chips. It accepts DCLK_IN, DE_IN, HS_IN/CS_IN, and VS_IN signals, processes data in the Component Processor, and outputs 16-bit 4:2:2 YCrCb. The ADV7402AKSTZ-110 does not decode HDMI packets but interfaces cleanly with HDMI receiver ICs.
