MAX2116-MAX2118
Complete DBS Direct-Conversion Tuner ICs with Monolithic VCOs
General DescriptionThe MAX2116/MAX2118 family of low-cost direct-
conversion tuner ICs are designed for use in digital
direct broadcast satellite (DBS) television applications,
professional VSAT systems, and two-way Internet
through satellite applications. These devices set the
standard for integration and performance, significantly
reducing the required RF know-how for design imple-
mentation. Uniquely architected, the MAX2116/MAX2118
simplify direct main board and tuner module designs.
The MAX2116/MAX2118 devices directly convert L-
band signals to baseband using a broadband I/Q
downconverter. The operating frequency range extends
from 850MHz to 2175MHz.
Each IC includes an LNA with gain control, I and Q
downconverting mixers, and baseband lowpass filters
gain and cutoff frequency control. Together, the RF and
baseband variable gain amplifiers provide more than
79dB of gain control range.
The devices include fully monolithic VCOs, as well as a
complete frequency synthesizer. Additionally, an on-
chip crystal oscillator is provided along with a buffered
output for driving additional tuners and demodulators.
Synthesizer programming and device configuration are
accomplished with a 2-wire serial interface. For multi-
tuner applications, each device can be configured to
have one of eight possible 2-wire interface addresses.
Simplifying the interface to low-voltage CMOS demodu-
lators, the MAX2116/MAX2118 incorporate two 2.85V
regulated outputs for pulling up open-drain interface
connections, thus preventing noisy 3V rails from cor-
rupting the sensitive analog signal of the tuners.
The MAX2116/MAX2118 devices are the most versatile
family of DBS products available. With both single-
ended and differential baseband outputs, these
devices are compatible with virtually all QPSK/8-PSK
demodulators. The tuners are available in a very small
(6mm x 6mm) 40-pin thin QFN package.
