ADV7202KST - 12-Bit 5-Channel Video Codec | Analog Devices
The Analog Devices ADV7202KST is a 12-bit simultaneous-sampling video-rate sampling codec capable of sampling up to five NTSC, PAL, or SECAM composite video input signals. The device combines one analog-to-digital converter, four digital-to-analog converters, a 64-pin LQFP package, and front-end resolution in which two of the 12 bits are assigned to gain and offset adjustment. It is designed for multi-channel analog video acquisition, conversion, and reconstruction systems.
A video codec is a mixed-signal interface IC that converts analog video into digital data and can also produce analog video outputs. In the signal-processing hierarchy, the ADV7202 belongs to the codec family, interface IC class, and broader data-conversion semiconductor category. Its five-input capability allows one device to support several standard-definition video sources, while its four DAC outputs support reconstruction or monitoring paths.
The principal verified features include simultaneous sampling of up to five composite video inputs, 12-bit front-end digitizer resolution, four video DAC channels, and 12-bit/10-bit digital data capability. The package is specified as 64-pin LQFP, also described in search data as PQFP64 or plastic LQFP-64. This integration can reduce the number of separate converters required in a video system, although exact timing, voltage, clock, output-format, and thermal details must be confirmed from the manufacturer documentation.
The architecture is suited to systems that need a consolidated analog-video interface rather than discrete converters. Simultaneous sampling is important when multiple composite signals must share a defined acquisition moment, while the multiple DACs provide parallel analog-output capability. Digital resolution, clocking, sync handling, and supported video standards remain critical system constraints that depend on the selected operating mode and the complete ADV7202 datasheet.
Typical uses include professional video test equipment, broadcast video monitoring, surveillance-system interfaces, video capture hardware, and multi-source analog-video switching systems. The component is particularly relevant when the board must ingest multiple composite video streams and retain flexible digital processing before conversion back to analog. Product selection should also account for source format, required resolution, supported clock, interface voltage, thermal conditions, and system timing.
A practical design review begins with the ADV7202 datasheet pinout, electrical tables, timing diagrams, and application guidance. PCB layout should preserve analog and digital return paths, provide appropriate decoupling, and route high-speed digital signals with controlled impedance. Since the verified data does not include complete pin assignments or operating limits, engineers should not infer those values from generic codec designs.
This page combines verified product, package, interface, and sourcing information with transparent data gaps, procurement guidance, and application-oriented engineering context. It distinguishes confirmed ADV7202KST facts from unverified parameters so designers can evaluate the codec efficiently without mistaking distributor summaries for a complete datasheet.
