Channel Clock
Recovery
The Channel Interface is the input path to the L64704 Satellite Decoder.
The two signal buses RI[5:0] and RQ[5:0] are the I and Q streams from
the satellite tuner circuit. The CLK signal discussed in the Channel Clock
Recovery section is used to strobe in the data signals. The Channel
Interface is discussed in
RI[5:0]
RQ[5:0]
The Channel Clock Recovery logic is the logic that recovers the clock for
the Channel Interface. Channel Clock recovery is discussed in
Section 5.5, “Channel Clock Recovery.”

Q Channel Data
Received Q Channel data input bus.
RI/Q Input Clock
CLK is a positive, edge-triggered clock that is used to
strobe in input data. It is not used anywhere else in the
L64704, and does not propagate past the Channel
Interface.
These two differential signals are the Positive and Nega-
tive Sigma Delta (
the Channel Clock VCO frequency.
Crystal Oscillator In
The XOIN pin is the crystal oscillator or external refer-
ence clock input.
Crystal Oscillator Out
The XOOUT pin is the crystal oscillator output pin.
