MTV320:  Dual Zero-IF Mobile TV tuner IC for DMB-Satellite

Product Description

The MTV320 is a dual highly integrated zero-IF tuner IC for digital multimedia broadcasting (DMB) diversity receiver via satellite, which conforms to ITU-R BO.1130-4 Digital System E standard. It operates from 2605 to 2655 MHz. It includes an LNA and direct conversion down mixers. On-chip low phase noise VCO, which eliminates external tank circuits, generates In phase and Quadrature phase local oscillator. Automatic tuned baseband channel select filters are available with automatic tuning. The MTV320 also includes high dynamic range baseband variable gain amplifier. A low noise amplifier and optimized gain control scheme enable wide dynamic range operation.

The MTV320 consumes less than 140 mW with diversity operation. Power down function reduces the standby mode current consumption for power hungry systems. Using small leadless 36-QFN package, the MTV320 is the best solution for portable DMB application especially for mobile phone, notebook PC, PDA, and etc. where low power consumption is critical. It has an industry standard I2C serial bus interface. Primary application of the MTV320 is the satellite digital multimedia broadcasting system.
