Description
24
1
OUT0
O
Programmable CMOS output. Level of the output is controlled by IF_N [17] bit.
1
2
Vcc
RF
-
RF PLL power supply voltage input. Must be equal to Vcc
IF. May range from 2.7 V to
5.5 V. Bypass capacitors should be placed as close as possible to this pin and be
connected directly to the ground plane.
23
V
pRF
-
Power supply for RF charge pump. Must be
≥V
ccRF and VccIF.
34
CP
oRF
O
RF charge pump output. Connected to a loop filter for driving the control input of an
external VCO.
4
5
GND
-
Ground for RF PLL digital circuitry.
5
6
fin RF
I
RF prescaler input. Small signal input from the VCO.
6
7
fin RF
I
RF prescaler complimentary input. A bypass capacitor should be placed as close as
possible to this pin and be connected directly to the ground plane.
7
8
GND
-
Ground for RF PLL analog circuitry.
8
9
OSCx
I/O
Dual mode oscillator output or RF R counter input. Has a Vcc/2 input threshold when
configured as an input and can be driven from an external CMOS or TTL logic gate.
Can also be configured as an output to work in conjunction with OSCin to form a
crystal oscillator. (See functional description 1.1 and programming description 3.1.)
