DESCRIPTION

The FI1200MK2 family consists of the following types
FI1216MK2, FI1246MK2, FI1256MK2. They are designed
to meet a wide range of RF applications in the PC
Multi-Media environment.

The FI1216MK2 types are available with a single 75 Ω
input for TV reception. The input connector is available in
either standard phono (female socket) or IEC (female
socket).

The tuning and bandswitching are performed through the
built-in digitally controlled I
input immunity and radiation of CENELEC.

The FI1216MK2 consists of a tuner section and an IF
section, which are all designed on a single PCB. The
front-end is assembled in a metal housing made of a
rectangular tin plated steel frame with front and rear covers
which have soldered contacts to the frame. A single phono
or IEC aerial socket is mounted on one side of the frame.
All other connections are made via pins at the bottom.

The tuner section is equipped with 3 tuned RF MOSFET
input stages, with a 3-band mixer-oscillator IC, containing
the oscillators, mixers and IF amplifier. Tuning and band
switching in the tuner section are done with a digital
programmable PLL tuning system. This enables tuning
with step-size programmable between 31.25,

50.0 or 62.5 kHz. A DC-DC converter is built around the

PLL synthesizer IC to provide the tuning voltage, thus
making the FI1216MK2 front-end a true 5 V device.

The IF section uses a true-synchronous vision IF
demodulator (PLL) with an intercarrier SAW filter in front
of it.

The analog AFC voltage is fed to the 5-level A/D converter
in the PLL tuning IC, so that the AFC status can be read
via the I2C-bus.
