L64733C/L64734 Tuner and Satellite Receiver Chipset
ADCVDDI/Q
ADC Power
Input
ADCVDDI/Q are the analog power supply pins for the
ADC module and normally are connected to the system
power (VDD) plane.
ADCVSSI/Q
ADC Analog Ground
Input
ADCVSSI/Q are the analog ground pins for the ADC
module and normally are connected to the system
ground plane.
FBUFVDD
Analog Supply
Input
FBUFVDD is the analog supply pin for the on-chip
reference voltage generator. This pin normally is
connected to the system power (VDD) plane.
FBUFVSS
Analog Ground
Input
FBUFVSS is the analog ground pin for the on-chip
reference voltage generator. This pin normally is
connected to the system ground (VSS) plane.
IBIAS
ADC Bias Current
Output
This is the bias current for the ADC module. Connect this
output to a 39 k
resistor, and connect the other side of
the resistor to ground.
AGC Control Interface
The AGC Control Interface contains signals used for power control.
AGC1, AGC2 Power Control
Output
The AGC1 and AGC2 signals are the positive
Σ
modulated output used for power control. These signals
can each drive an external passive RC lter that feeds a
gain control stage for dual-stage AGC. For a single stage
AGC, AGC1 can be used, and has the same functionality
as the PWRP pin on the L64724.
Channel Data Output Interface
The Channel Data Output Interface is the output path from the L64734.
It typically is connected to the input of the transport demultiplexer in a
set-top decoder application.
