Overview
The ADV7400KST-110 is a multiformat video decoder and RGB graphics digitizer from Analog Devices. It integrates 10-bit Noise Shaped Video ADCs with an 8-bit accurate output interface for cost-sensitive applications. The device supports NTSC, PAL, and SECAM standards alongside full component HDTV inputs including 525p, 625p, 720p, and 1080i. It features a 110 MSPS conversion rate supporting RGB resolutions up to 1280x1024 at 60 Hz. The chip includes a digital RGB input port, Any-to-Any color space converter, and VBI data slicer.
Feature Summary
- Integrates 10-bit Noise Shaped Video ADCs for true video data processing accuracy across all sources up to HDTV rates.
- Supports worldwide color formats including NTSC, PAL, and SECAM, plus full component HDTV input support.
- Features a fully certified Macrovision detection system and adaptive digital line length tracking for robust sync stability.
- Includes a 24-bit digital RGB input port accepting data from common DVI/HDMI receivers.
Applications
- Home theater projectors
- Direct view HDTVs
- Rear projection HDTVs
Procurement Notes
Verify the specific speed grade suffix (110) matches the required resolution and refresh rate specifications. Confirm package type and temperature range requirements against the datasheet. Ensure I2C compatibility and power supply voltages align with the target design constraints before finalizing procurement.
Selection Notes
Select this model when high performance 10-bit ADCs are needed with an 8-bit accurate output interface for cost-sensitive designs. The 110 MHz speed grade supports SXGA resolutions at 60 Hz. Consider the ADV7402 if 12-bit decoding is required instead of the 10-bit architecture provided by the ADV7400 series.
Part Context
The ADV7400KST-110 belongs to the ADV7402/ADV7400 family of multiformat video decoders designed for advanced TV applications. These devices simplify front-end digitizer architectures by reducing board space and system power consumption. They replace separate decoder and ADC chips in home theater and direct view/rear projection HDTV configurations.
Replacement Considerations
The ADV7400KST-80 offers the same functionality with an 80 MHz ADC speed grade suitable for 1080i/720p maximum resolutions. The ADV7400KST-140 provides a 140 MHz speed grade supporting SXGA at 75 Hz. The ADV7402 variants offer 12-bit decoding capabilities.
