L64733C/L64734 Tuner and Satellite Receiver Chipset
FDOUB
Frequency Doubler
Input
When FDOUB is asserted, the L64733C local oscillator
frequency is internally doubled and fed to the mixers.
When FDOUB is deasserted, the oscillator frequency is
not doubled before being fed to the mixers.
Bit 6 of register 79, group 4 (APR 79), controls the
L64734 FDOUB output pin, which enables or disables the
frequency doubler on the L64733C.
The FDOUB pin is set as shown in the table below, where
Fswitch is the frequency at which the frequency doubler is
enabled or disabled.
This method of control preserves the compatibility with
the L64733B, which is not affected by 3-stating the
FDOUB pin.
FLCLK
Filter Clock
Input
The FLCLK signal is a low amplitude, self-biased clock
input. The frequency of the FLCLK signal multiplied by 16
is the baseband lter’s
3 dB frequency.
IDCp, IDCn
I-Channel DC Offset Correction
Input
Connect a 0.1
F or larger capacitor between the IDCp
and IDCn signals.
INSEL
RF Port Input Select
Input
When the INSEL signal is asserted, the L64733C is in
normal mode. When the INSEL signal is deasserted, the
L64733C is in Loop-Through mode. In this mode, the
RFIN signal is looped through out to the RFOUT signal
and the L64733C local oscillator is shut off.
LOBUF
Local Oscillator Buffer Select
Input
Asserting LOBUF causes the external PLL mode to be in
effect, the local oscillator (LO) buffer to be enabled, and
the LO signal to be sent out to the PSOUT pins according
to the division ratio selected with the LODIV signal. When
