This document serves as a guideline to maximize the performance of this module for various
applications.
1.
Introduction
The FM1200Mk3 and FQ1200Mk3 are the new family of RF video modules family. The MK3
family is the small size front-ends which is designed to meet wider range of RF applications in the
areas like PC/TV Multi-Media; LCD TV; PVR and etc. It combines the functions of an all bands
tuner, and a Quasi-Split Sound (QSS) IF Demodulation unit.
The frontends have a built-in digital (I
2
C) PLL tuning system. A DC-DC converter circuit is built-
in to synthesize the tuning voltage, thus making the frontends the true 5V device.
The FQ1200Mk3 and FM1200MK3 are complied all the requirements of FCC, CISPR, JIS, DOC
(canada) as well as CENELEC (EN55013, EN55020) with respect to input immunity and EMC.
