MAX2116/MAX2118 Complete DBS Direct-Conversion Tuner ICs with Monolithic VCOs

PublishTime：2021-06-21

●The 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 l/Q downconverter. The operating frequency range extends from 850MHz to 2175MHz.
Each IC in eludes 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 in terface to low-voltage CMOS demodulators, the MAX2116/MAX2118 incorporate two 2.85V regulated outputs for pulling up open-drain interface connections, thus preventing noisy 3V rails from corrupt! ng 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.
