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 variable-gain amplifiers, and bandpass filters providing in excess of 42dB 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 100dB of gain-control range. The MAX2160/EBG also include fully monolithic VCOs and tank circuits, as well as a complete 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 low-cost interfacing to various channel decoders. The MAX2160/EBG are specified for operation from -40°C to +85°C and available in a 40-pin (6mm x 6mm) thin QFN lead-free plastic package with exposed paddle (E
The MAX2160 and MAX2160EBG are low‑IF tuner ICs designed for Japanese mobile digital TV (ISDB‑T single‑segment). They convert UHF band signals to a low‑IF using a broadband I/Q down‑converter and support both I/Q and single low‑IF interfaces. The devices integrate LNA, variable‑gain amplifiers, mixers, filters and a complete frequency synthesizer in a compact QFN or wafer‑level package.
