QOUTp, QOUTn
Q Channel Baseband Data
Output
The QOUT differential signals form the quadrature-phase
data provided to the L64734.
Prescaler Signals
The following signals are the prescaler outputs from the L64733C to the
L64734.
PSOUTp
, PSOUTn
Prescaler
Output
When the LOBUF signal is LOW, the PSOUT differential
signals are the L64733C prescaler outputs.
When LOBUF is HIGH, the Local Oscillator (LO) buffer
(50
) feeds the PSOUT differential signals.
The programmable counters on the L64734 are clocked
on the rising edge of the PSOUT signal.
Control Signals
The following signals, some of which are generated by the L64734 IC,
control the mode of operation of the L64733C IC.
AGC1
Automatic Gain Control 1
Input
The AGC1 signal is a high-impedance input from the
L64734 that controls RF AGC circuitry. The AGC1 voltage
has a range of 0.5 V to 4.8 V.
AGC2
Automatic Gain Control 2
Input
The AGC2 signal is a high-impedance input from the
L64734 that controls RF AGC circuitry.
CPG[2:1]
Charge Pump Gain
Input
The CPG[2:1] signals set the charge pump gain
according to the table below.
