MAX2160
Description
The MAX2160/EBG tuner ICs are designed for use in Japanese mobile digital TV (ISDB-T single-segment) applications. The devices directly convert UHF band signals to a low-IF using a broadband I/Q downconverter. The operating frequency range extends from 470MHz to 770MHz. The MAX2160/EBG support both I/Q low-IF interfaces as well as single low-IF interfaces, making the devices universal tuners for various digital demodulator IC implementations. The MAX2160/EBG include an LNA, RF variable-gain amplifiers, I and Q downconverting mixers, low-IF variablegain amplifiers, and bandpass filters providing in excess of 42d B of image rejection. The parts are capable of operating with either high-side or low-side local oscillator (LO) injection. The MAX2160/EBG’s variable-gain amplifiers provide in excess of 100d B of gain-control range. The MAX2160/EBG also include fully monolithic VCOs and tank circuits, as well as a plete frequency synthesizer. The devices include a XTAL oscillator as...
