PIN DESCRIPTIONS (continued)

12

C1

O (ANLG)

Noise Shunt. Negative voltage generator bypass capacitor connection.

Typically a 100nF capacitor is connected between pin C1 and C2

13

VPA

O (ANLG)

PA supply. This is the positive supply for the PA. It is switched by PAEN

in conjunction with PDN and NEGEN

14

PDN

I (ANLG)

Power down control. Disables all circuits and reduces power

consumption to less than 1mA

15

XIN

I (ANLG)

Crystal or oscillator input. This high input impedance is connected to

either an oscillator circuit or to a crystal

16

XOUT

I (ANLG)

Crystal-tank connection. This low impedance output drives the crystal

tank circuit
