BATTERY DETECTION
When the LBD active register = 1, the low battery detector is enabled and the signal BDout passes to the output CDLBD.
If V
CC
is below the programmed LBD level, CDLBD = 0; if not below the programmed level, CDLBD = 1. The power-up
default value is 110.
Table 13
LBD level register
7.9.8
OWER AMPLIFIER OUTPUT LEVEL
The power amplifier output register has two bits to modify the output power and one bit to disable the power amplifier
(PA output bit 2 = 0). Duplexer matching (300
to 50
)
is performed using a parallel inductive/series capacitive
network. Output power on 50
is specified in Table 14. To get power on the antenna, duplexer insertion loss should be
removed. At maximum power, 3 mA extra DC current is consumed compared with the current at the minimum power
settings.

PA output register

PLL
CHARGE PUMP CURRENT
Performance of the PLLs can be improved by increasing charge pump current. Then a programmable current on both
RX and TX charge pump can be programmed. RX and TX charge pump currents are programmed independently. When
the RX or TX charge pump current register = 0, charge pump current is 400
μ
A; when it is set to 1, charge pump current
is 800
μ
A.
