MAX2112CTI+

The MAX2112CTI+ is a complete, direct conversion tuner for DVB-S2 applications in 28 pin thin QFN-EP package. It is a low-cost, direct-conversion tuner IC is designed for satellite set to p and VSAT applications. The IC is intended for 8PSK and Digital Video Broadcast (DVB-S2) applications. The MAX2112 directly converts the satellite signals from the LNB to baseband using a broadband I/Q down converter. The operating frequency range extends from 925MHz to 2175MHz. The device includes an LNA and an RF variable-gain amplifier, I and Q down converting mixers and baseband low pass filters with programmable cut-off frequency control and digitally controlled baseband variable-gain amplifiers. Together, the RF and baseband variable-gain amplifiers provide more than 80dB of gain control range. The IC is compatible with virtually all DVB-S2 demodulators. The MAX2112 includes fully monolithic VCOs, as well as a complete fractional-N frequency synthesizer.
