Microtune introduced a new silicon tuner, the MT2063, which it claims is unique in meeting the requirements for multiple TV reception standards—analog/digital and off-air/cable—across worldwide markets. The MT2063 is capable of receiving frequencies in the 48 to 1002 MHz range and converts a selected channel to standard intermediate frequencies (IF) between 30 and 60 MHz.

The tuner uses dual conversion and eliminates the need for external tracking filters with an integrated preselection filter on the RF input, low in-band emissions and “outstanding image rejection.” In addition to the RF pre-filter, it includes a first IF filter. An integrated LNA contributes to a quoted terrestrial TV noise figure of 5 dB.

Microtune said the tuner is “fully compatible with ATSC, DVB-T, DMB-T, ISDB-T, QAM/DVB-C, NTSC, PAL, SECAM and other terrestrial TV standards.”

Refer to the MT2063 Product Sheet for additional information. The tuner is priced at $3.50 per unit in high volume. Evaluation boards and reference designs are available.
