Product details
Overview
ADV7402KST-110 from Analog Devices is a 12-bit multiformat SDTV/HDTV video decoder and RGB graphics digitizer with three 110 MHz Noise Shaped Video® ADCs, supporting NTSC/PAL/SECAM composite/S-video, 525p/625p/720p/1080i component video, and RGB graphics up to 1280×1024@60 Hz (SXGA) for HDTV STB and PVR applications.
For engineers reviewing the ADV7402KST-110 datasheet, ADV7402KST-110 pinout, ADV7402KST-110 application, or ADV7402KST-110 equivalent, this page delivers verified technical context, confirmed pin functions, real-world timing and noise performance metrics, and validated alternative options for video signal chain design in broadcast-grade consumer electronics.
Technical Context
The ADV7402KST-110 integrates two independent processing cores: a Standard Definition Processor (SDP) handling PAL/NTSC/SECAM via 4× oversampled 54 MHz CVBS/S-video paths with adaptive 2D 5-line comb filtering and Macrovision 7.1 detection; and a Component Processor (CP) supporting 1×–2× oversampled YPrPb/RGB at up to 110 MSPS with programmable 3×3 color space conversion and embedded sync extraction.
Its analog front end uses differential 12-bit ADCs with voltage/current clamping, fine digital clamping, and configurable gain/offset control per channel. The device outputs pixel data in ITU-R BT.656 4:2:2 YCrCb or 4:4:4 RGB formats across 24-bit parallel ports, synchronized to LLC1 (13.5–110 MHz), with HS/VS/FIELD/DE timing signals and dual I²C interfaces (control + VBI readback).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 12-bit with Noise Shaped Video® architecture enabling true 10-bit effective resolution in high-SNR video decoding. |
| Max Input Sampling Rate | 110 MSPS for RGB graphics digitization (e.g., SXGA @ 60 Hz), ensuring full-bandwidth capture without aliasing. |
| Luma SNR (unweighted) | 64 dB (flat field), directly enabling broadcast-grade luminance fidelity in CRT/LCD/PDP display systems. |
| Differential Phase Error | 0.4° typical for CVBS input, meeting stringent NTSC/PAL color accuracy requirements for consumer HDTV. |
| Color Space Conversion | Programmable any-to-any 3×3 matrix supporting YCrCb↔RGB conversion with hardware-accelerated pixel-level math. |
| Power Supplies | 1.8 V DVDD (digital core), 3.3 V AVDD/DVDDIO (analog & I/O), 1.8 V PVDD (PLL) - enabling low-noise mixed-signal partitioning. |
| Operating Temperature | −25°C to +70°C, validated for industrial-grade reliability in enclosed HDTV STB and projector thermal environments. |
Pinout & Package
ADV7402KST-110 is housed in a 100-pin, 14 mm × 14 mm Pb-free LQFP package with exposed thermal pad (θJA = 30°C/W on 4-layer PCB). Pin assignments are fully defined per Analog Devices Rev. 0 datasheet Figure 2 and Table 7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1–AIN12 | Analog video input channels | 12-channel mux supports simultaneous connection of CVBS, S-video, YPrPb, and RGB sources without external switching. |
| P0–P29 | Pixel data I/O port | 24-bit parallel output (YCrCb/RGB) or input (DVI/HDMI Rx data), configurable for 16-/20-/24-/30-bit bus widths and SDR timing. |
| LLC1 | Line-locked clock output | Programmable 13.5–110 MHz pixel clock synchronized to active video lines - eliminates timing jitter in downstream FPGA/ASIC interfaces. |
| HS/CS, VS, FIELD/DE | Synchronization outputs | HS/VS provide standard timing; FIELD/DE doubles as field sync or data enable for direct HDMI Tx IC interfacing. |
| SCLK1/SDA1, SCLK2/SDA2 | Dual I²C interfaces | Separate control (0x40/0x42) and VBI readback (0x21/0x23) ports enable concurrent register programming and closed-caption data extraction. |
Key Features
| Feature | Design Value |
|---|---|
| Super Adaptive 2D 5-line Comb Filter | Automatically optimizes chroma/luma separation for NTSC/PAL composite inputs without user tuning - critical for VCR/tuner signal robustness. |
| ADLLT™ Algorithm | Adaptive Digital Line Length Tracking locks to unstable line lengths from VCRs and camcorders, preventing frame tearing and sync loss. |
| Macrovision® 7.1 Detection | Hardware-certified detection of Types I/II/III copy protection on both composite/S-video and component (525i/625p) inputs - required for STB compliance. |
| Arbitrary Pixel Sampling | Supports non-standard resolutions and timing (e.g., custom VGA variants) via programmable sampling PLL and 32-phase DLL alignment. |
| Free-Run Output Mode | Generates stable pixel clock and sync signals even with no valid video input - essential for seamless source switching in multi-input systems. |
Applications
| LCD/DLP Rear Projection HDTV | HDTV Set-Top Box with PVR |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiformat video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7403KSTZ | Same 100-pin LQFP package and pinout; adds integrated 3D comb filter and enhanced CTI for superior motion artifact suppression. | Targeted at premium HDTV displays requiring higher motion clarity; lacks ADV7402KST-110's specific 110 MSPS RGB graphics support. | Select ADV7403KSTZ when motion fidelity outweighs SXGA graphics digitization needs. |
| THS8200IPHP | 10-bit ADC resolution, 80 MSPS max sampling, single-core architecture, no Macrovision certification, 64-pin HTQFP package. | Designed for cost-optimized DLP projector front-ends with simpler SD/EDTV focus; not suitable for HDTV STB PVR or 1080i component decoding. | Choose THS8200IPHP only for legacy SDTV-centric designs where 12-bit fidelity and HDTV compliance are not required. |
Compared with ADV7402KST-110, ADV7403KSTZ improves motion handling but sacrifices RGB graphics bandwidth, while THS8200IPHP reduces cost and size at the expense of resolution, HDTV support, and copy protection compliance - making ADV7402KST-110 the balanced choice for multiformat broadcast-grade systems.

FAQ
What video standards does the ADV7402KST-110 support for composite and S-video inputs?
The ADV7402KST-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, with full automatic detection and autoswitching. It processes these signals through its Standard Definition Processor using 4× oversampling at 54 MHz and adaptive 2D 5-line comb filtering to ensure accurate chroma/luma separation.
Does the ADV7402KST-110 support RGB graphics digitization, and what is the maximum resolution?
Yes, the ADV7402KST-110 supports RGB graphics digitization up to 1280×1024 @ 60 Hz (SXGA) at 110 MSPS using its Component Processor core. This capability enables direct capture of PC graphics outputs for integration into HDTV displays and multimedia projectors, with programmable clamp, gain, and 3×3 color space conversion applied in real time.
What is the function of the FIELD/DE pin on the ADV7402KST-110?
The FIELD/DE pin on the ADV7402KST-110 serves dual functionality: in interlaced video modes (e.g., 525i, 1080i), it outputs a field synchronization signal; in component processor (CP) mode, it can be configured as a data enable (DE) signal for direct connection to HDMI or DVI transmitter ICs, simplifying timing interface design without external logic.
Is Macrovision copy protection detection supported on the ADV7402KST-110, and which inputs does it cover?
Yes, the ADV7402KST-110 includes certified Macrovision® 7.1 detection circuitry supporting Types I, II, and III protection levels on both composite/S-video inputs and component video (525i, 625i, 525p, 625p) - a key requirement for HDTV STBs and PVRs targeting North American and European broadcast markets.
What power supply voltages are required for the ADV7402KST-110, and how are they distributed?
The ADV7402KST-110 requires four independent supplies: 1.8 V DVDD for the digital core, 3.3 V AVDD for analog circuitry, 3.3 V DVDDIO for digital I/O, and 1.8 V PVDD for the PLL. This partitioning minimizes noise coupling between analog video paths and digital logic, ensuring >64 dB luma SNR and <0.4° differential phase error under full-load conditions.
