ISDB-T Single-Segment Low-IF Tuners
General Description
Features
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 downconvert-
er. The operating frequency range extends from
470MHz to 770MHz.
♦ Low Noise Figure: < 4dB Typical
♦ High Dynamic Range: -98dBm to 0dBm
♦ High-Side or Low-Side LO Injection
♦ Integrated VCO and Tank Circuits
♦ Low LO Phase Noise: Typical -88dBc/Hz at 10kHz
♦ Integrated Frequency Synthesizer
♦ Integrated Bandpass Filters
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.
♦ 52dB Typical Image Rejection
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 operat-
ing with either high-side or low-side local oscillator (LO)
injection. The MAX2160/EBG’s variable-gain amplifiers pro-
vide in excess of 100dB of gain-control range.
♦ Single +2.7V to +3.3V Supply Voltage
♦ Three Low-Power Modes
♦ Two-Wire, I2C*-Compatible Serial Control Interface
♦ Very Small Lead-Free WLP Package
Pin Configurations/
Functional Diagrams
The MAX2160/EBG also include fully monolithic VCOs
and tank circuits, as well as a complete frequency syn-
thesizer. 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 hand-
set applications. Additionally, a divider is provided for
the XTAL/TCXO oscillator allowing for simple and low-
cost interfacing to various channel decoders.
