NAME
FUNCTION
XTAL1
Crystal Input 1 (See the
Phase-Locked Loop
section)
Positive Analog Supply Voltage. For +5V operation, AV
DD
is connected to an on-chip +3.2V
low-dropout regulator. Both AV
DD
pins must be externally connected to each other. Bypass
each pin to AGND with a 0.01μF capacitor as close to the pin as possible (see the
Typical
Application Circuit
).

LNASRC
Low-Noise Amplifier Source for External Inductive Degeneration. Connect inductor to ground
to set the LNA input impedance (see the
Low-Noise Amplifier
section).

MIXIN1
MIXIN2
1st Differential Mixer Input. Connect to LC tank filter from LNAOUT.
2nd Differential Mixer Input. Connect through a 100pF capacitor to AV
DD
side of the LC tank.

IRSEL
Image-Rejection Select. Set V
IRSEL
= 0V to center image rejection at 315MHz. Leave IRSEL
unconnected to center image rejection at 375MHz. Set V
IRSEL
= V

AC
Automatic Gain Control. See Figure 1. Internally pulled down to AGND with a 100k
resistor.
Crystal Divider Ratio Select. Drive XTALSEL low to select divider ratio of 64, or drive
XTALSEL high to select divider ratio of 32.
