Description

The MAX2112 low-cost, direct-conversion tuner IC is designed for satellite set-top and VSAT applications. The IC is intended for 8PSK and Digital Video Broadcast (DVB-S2) applications. The device directly converts the satellite signals from the LNB to baseband using a broadband I/Q downconverter.

The operating frequency range extends from 925MHz to 2175MHz. The device includes an LNA and an RF variable-gain amplifier, I and Q downconverting mixers, and baseband lowpass filters with  rogrammable cutoff 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.

Description

The TEF6624, TEF6624T is an AM/FM radio including Phase-Locked Loop (PLL) tuning system. The system is designed in such a way, that it can be used as a world-wide tuner covering common FM and AM bands for radio reception. All functions are controlled by the I2C-bus. Besides the basic feature set it provides a good weak signal processing function and a dynamic bandwidth control at FM reception.
