Channel Interface
14
The following signal descriptions are listed according to the major
interface groups.
The Channel Interface is the input path to the L64734 satellite receiver.
IVIN and QVIN are the I and Q streams, respectively, from the satellite
tuner circuit. The CLK signal strobes in the data signals.
IBYPASS[5:0] I Channel Data

Tuner Control
The IBYPASS[5:0] signals form the digital I channel data
input bus, which supplies the I Stream to the L64734
when the ADC is bypassed. Bypass is controlled through
the setting of particular register bits in the L64734.
I Channel Data
These differential signals form the analog received I
channel data input bus, which supplies the I stream to the
L64734.
Q Channel Data
The QBYPASS[5:0] signals form the digital received
Q channel data input bus, which supplies the Q Stream
to the L64734 when the ADC is bypassed. Bypass is
controlled through the setting of particular register bits in
the L64734.
Q Channel Data
The QVINn and QVINp differential signals form the
analog received Q channel data input bus, which supplies
the Q stream to the L64734.
