Product Summary

The MT2131F is a high-performance single-chip tuner for ATSC and Digital Cable-Ready ATSC television receivers and set-top boxes. The MT2131F receives frequencies in the 48 MHz to 1 GHz range and converts a selected channel to a standard intermediate frequency (IF) between 30 MHz and 57 MHz. The MT2131F dual-conversion architecture yields consistent ATSCA/74 and FCC Digital Cable-Ready (DCR) compliant performance without any manual adjustments. The MT2131F is achieved via the combination of Microtune ClearTune technology and an autonomous automatic gain control(AGC).
