DESCRIPTION
The FI1200MK2 family of front ends are designed to meet
a wide range of RF applications in the PC Multi-Media
environment.
The FI1216MF MK2 type 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 requirements of CENELEC.
(“CENELEC 55020, 55013”)
2
C-bus. All front ends meet the
FI1216MF MK2
The FI1216MF MK2 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 FI1216MF MK2 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 I

Remark: for channel selection involving band switching, and to ensure smooth tuning to the desired channel without
causing unnecessary charge pump action, it is recommended to consider the difference between wanted channel
frequency (fw) and the current channel frequency (fc):
Unnecessary charge pump action will result in very low tuning voltage (VT≈ 0 V) which may drive the oscillator to extreme
conditions.

drops below 3 V. The POR bit is reset when an end of

data is detected by the PLL IC.

7.8125 kHz reference frequency before the FL flag is internally set to 1.

Video buffer
A video buffer is built into the video module to enable the
unit to drive a 75 Ω load directly. In case it is required to
use the FI1216MF MK2 as a replacement for the FI1216 in
the same videocard, it is necessary to replace the 75 Ω
series resistor in the video card by a 0 Ω series resistor. At
the same time the 22 kΩ series resistor in the tuning
supply must be removed.

C-bus load
I
The FI1216MF MK2 contains a series resistor (R = 100 Ω)
in the SCL and SDA lines. Both lines also have a
capacitive load of typical 56 pF (see Fig.3).
