The 41x6 Series RF Tuner
Modules are complete RF front-
end systems specifically
designed for multimedia PC/TV
applications. The modules
contain two primary functional
components: a hyperband tuner
and an intermediate frequency
(IF) section.
The tuner offers frequency
options in the 45 MHz to
868 MHz range. The reception
frequency range is divided into
VHF low, VHF high, and UHF.
Band selection and tuning are
accomplished via I
2
C serial bus.
The IF section includes a SAW
filter, an IF amplifier, and video
and sound demodulators. The
CVBS signal is available via a
built-in video buffer at the video
output terminal, suitable for a
75鈩?load. The audio signal is
available at the audio output
terminal.
A second IF output is provided
for external sound demodulation
for stereo and NICAM reception.
A DC/DC converter for 33V
generation is built in, so that only
a single supply voltage of 5V is
required.
