The MAX2112 is a low-cost, zero-IF, direct-conversion tuner IC for satellite TV. The chip receives QPSK and 8PSK signals in the 925 to 2175MHz range and downconverts them to baseband for demodulation. It provides a low, 8.0dB noise figure and wide, -75dBm to 0dBm dynamic range, thus eliminating the need for an external LNA. Additionally, its VCO autotuner function simplifies firmware for ease of use. The tuner targets DVB-S2 and free-to-air applications. It operates from a single 3.3V supply, consumes only 300mW and is designed for use with a 27MHz crystal. The IC is packaged in a 5x5mm, 28-pin TQFN and is available in both the 0 to +70°C and -40 to +85°C temperature ranges.
