Pin 15 is the V
CC
supply pin for
the downconverter block. This pin is
independent of the V
CC
pin for the IF
amplifier. Apply 3 V to pin 15.
This pin is the ground pin for the
entire chip. Therefore the ground of
the IF downconverter and IF amplifier
blocks are not separated. The ground
pattern to be connected to this pin
should be formed as wide as
possible to minimize its impedance.
Pins 10 and 11 are not connected
to the internal circuits. Connecting
these pins to GND is recom-
mended, though these pins may
be left unconnected.

Pin 14 is the V
CC
supply pin for
the IF amplifier. This pin is
independent of the V
CC
pin for the
downconverter unit. Apply 3 V to
pin 16.
Pin 16 is the gain control pin for
the AGC amplifier. The gain of
the AGC amplifier is controlled by
the applied voltage on this pin.
Pins 17 and 18 are the LO input
pins of the mixer. The LO Bypass
pin should be connected to GND
via a bypass capacitor.
Pins 1 and 20 are the output pins
of the mixer block. These pins are
used to monitor the signal output
from the IF amplifier and to be
input to the AGC amplifier. When
the IC is actually used, these pins
should be left opened.
