FUNCTIONAL DESCRIPTION
6.1
PCF26100 overview
The adapter features a Power-on reset which is used to
reset the adapter logic. There is also a POR_EXT signal
which is used for controlling the reset of the PCF26100
within the application.
The system clock for the application is generated by the
PCF26100. The system clock is then provided to the
baseband SYS_CLK and the radio REF_CLK. Both the
SYS_CLK and REF_CLK clocks are controlled within the
PCF26100.
From the system clock a low-power 3.2 kHz clock
LPO_CLK is generated.
From the PCF26100 a 1 MHz TX_CLK is generated to be
used in the baseband controller to clock out the transmit
data on TX_DATA.
The serial interface to the baseband controller is a JTAG
interface. This interface is used to initialize and control the
PCF26100 and subsequently the radio. The channel
information received from the JTAG interface is converted
and forwarded to the radio 3-wire S-bus interface.
The timing control signals to the UAA3558 radio are
generated in the PCF26100. For this a minimum number
of reference timing signals from the baseband controller
are used. The exact timing of the control signals is
programmable in the PCF26100.
The PCF26100 converts the digital transmit data from the
baseband controller to analog gaussian shaped transmit
data to the radio.
The analog RSSI from the radio is converted to digital and
made available to the baseband controller via the JTAG
interface.
The digital power amplifier control information
communicated from the baseband controller to the
PCF26100isconvertedtoananalogcontrolvoltageforthe
radio.
The PCF26100 provides an identification number, which
can be read by the baseband controller through the JTAG
interface.
For frequency compensation and tuning, the PCF26100
provides a tuning capability on the system oscillator.
