and Q LO signals to the down-conversion

mixers in receive mode and up-conversion

mixers in transmit mode. The VCO

operates in the frequency range 4800 –

4966 MHz, and the frequency is divided by

two when split in I and Q.

provides the reference frequency for the

synthesizer. A digital lock signal is

available from the PLL.

The digital baseband includes support for

frame handling, address recognition, data

buffering and MAC security.

The 4-wire SPI serial interface is used for

configuration and data buffering.

An on-chip voltage regulator delivers the

regulated 1.8 V supply voltage. The

voltage regulator may be enabled /

disabled through a separate pin.

A battery monitor may optionally be used

to monitor the unregulated power supply

voltage.
