Data register content description
Notes
1.
Sideband select enables the user to have the RX local oscillator in or out of the ISM band and to use the same IC in
both handset and base.
A 4.5 dB insertion loss in the filter is assumed.
The clock output signal will be AC-coupled with the XTALI pin of the microcontroller. The external resonator from the
microcontroller can be removed. Caution needs to be taken that no radiation is present on the PCB
In inactive mode, the crystal oscillator is a major contributor to the full current consumption. When Xtal high = 0, the
current mode can be programmed to save current and in inactive mode this comes to full current consumption at
230
μ
A (see Section 7.1.3). When Xtal high = 1, the crystal oscillator current is increased by 100
μ
A.
Depending on the SBS-bit and the protocol chosen, the data may be inverted between the base and handset data
transmission.
Minimum supply voltage for the IC is 2.9 V which limits the voltage swing on both charge pumps to approximately
2.3 V. With the voltage doubler or with an external high supply voltage on pin V
CC(CP)
, the extra voltage availability
can be used to enhance the tuning range of the VCOs variable capacitance diodes. To save current in inactive mode,

voltage doubler clock is the same as CLKO clock (can be programmed to
); in other modes the voltage doubler
clock is XTALI divided by two.
