.. 19-0068; Rev 3; 12/05 KIT ATION EVALU E L B A IL AVA ISDB-T Single-Segment Low-IF Tuners General 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 well as a separate TCXO input buffer. The devices operate with XTAL/TCXO oscillators from 13MHz to 26MHz allowing the shared use of a VC-TCXO in cellular handset applications. Additionally, a divider is provided for the XTAL/TCXO oscillator allowing for simple and lowcost interfacing to various channel decoders. The MAX2160/EBG are specified for operation from -40°C to +85°C and available in a 40-pin thin QFN leadfree plastic package with exposed paddle (EP), and in a lead-free wafer-level package (WLP).
