Function and Application
35 RX-MIXout
1.68
Output pin of RF mixer.
1st IF filter must be inserted
between pin 33 & 35.
36 VCC (RF-MIX) 2.7 to 3.3
Supply voltage pin of RF mixer
block. This pin must be
decoupled with capacitor
(example: 1 000 pF).
1 RF-MIXin
1.20
Input pin of RF mixer.
1 575.42 MHz band pass filter
can be inserted between pin 1
and external LNA.
2 GND (RF-MIX)
0
Ground pin RF mixer.
3 VCC
2.7 to 3.3
Supply voltage pin of differential
(1stLO-OSC)
amplifier for 1st LO oscillator
circuit.
4 1stLO-OSC1
5 1stLO-OSC2
1.88
Pin 4 & 5 are each base pin of
differential amplifier for 1st LO
oscillator. These pins should be
1.88
equipped with LC and varactor
to oscillate on 1 636.80 MHz as
VCO.
6 GND
0
(1stLO-OSC)
Ground pin of differential
amplifier for 1st LO oscillator
circuit.
7 VCC (phase
2.7 to 3.3
Supply voltage pin of phase
detector)
detector and active loop filter.
8 N.C.

Pins of active loop filter for
tuning voltage output.
The active transistors
configured with darlington pair
are built on chip. Pin 11 should
be pulled down with external
resistor. Pin 9 to 10 should be
equipped with external RC in
order to adjust dumping factor
and cutoff frequency. This
tuning voltage output must be
connected to varactor diode of
1st LO-OSC.
12 GND (phase
0
detector)
Ground pin of phase detector +
active loop filter.
