Modules can be implemented with different sockets,
filters, interfaces, connectors, and other customizable
options within the same pinouts.
The 404x Series RF Tuner
Module is specifically designed
for mixed digital and analog TV
reception. This device combines
the functions of both an analog
multimedia front end and a
digital tuner in a single unit.
For reception of digitally
modulated signals, a balanced IF
output has a center frequency of
44 MHz. The IF outputs connect
directly with an applicable
external SAW filter. An AGC
control input allows for external
control of the output signal
amplitude. This tuner covers a
frequency range of 50 MHz to
860 MHz with a channel
bandwidth of 6 MHz.
The module’s hyperband tuner
for analog TV reception covers
the frequency range of 50 MHz
to 860 MHz and contains an IF
part with SAW filter, IF amplifier,
and video and sound
demodulators. The AF and CVBS
signals are available at the audio
and video output pins. A video
buffer is built in for direct
connection to a 75Ω input.
For both digital and analog
applications, the reception
frequency range is divided into
VHF low, VHF high, and UHF.
Band selection and tuning are
done completely via the I²C-bus.
In addition, the AFC voltage
generated by the IF demodulator
is fed to an integrated A/D
converter in the PLL IC and is
readable via the I²C bus. A
digital AFC function can be
implemented.
A DC/DC converter for 33V
generation is built in, so that only
a single supply voltage of 5V is
required.
