Microtune MT2068
The MT2068 is a low-power 3.3 V single-chip broadband tuner with an integrated IF variable-gain amplifier. The MT2068 is capable of receiving frequencies in the 48 MHz to 1.0 GHz range and of converting a selected channel to a standard intermediate frequency (IF) between 30 MHz and 60 MHz. The MT2068’s low phase noise makes it ideal for use in digital applications such as video, voice and high-speed data.| Part No. | MT2068 |
