PBA 313 01
EN/LZT 146 65 R3B Ericsson Microelectronics AB, October 2001
I/O Signal Description
Power supply
There are two connections to supply the Bluetooth radio with
power. VCC_VCO supplies the sensitive VCO circuitry with
power, and VCC is for the remaining circuitry. Each of the two
supplies should be low frequency decoupled. See figure 13
for example circuitry.
Oscillator or external clock input
Refer to the Design Considerations section.
Oscillator or external clock input XO_N and XO_P connects to
the crystal's inputs. The load capacitance to the crystal can
be trimmed using the XO-Trim register. If an external clock is
used, it should be AC coupled into the XO_N input and the
XO_P input shall be left unconnected.
Antenna
The ANT pin should be connected to a 50 antenna interface,
thereby supporting the best signal strength performance.
Ericsson Microelectronics' partners can support application
specific antennas.
Input Control
There are six digital inputs available for controlling the radio
features of the PBA 313 01. The Bluetooth timing require-
ments for these are decribed in figure 6. In addition, there is
a digital input signal for hardware reset of the radio, and a
digital input signal for waking up the clock circuitry after a
sleep mode period.
SYNT_ON
Synthesizer on control is active 'high'. Activate this signal to
power up of the VCO section of the radio. SYNT_ON is used
in both transmit and receive mode.
RX_ON
Receive-on control is active 'high'. Activate this signal to
enable reception of Bluetooth data on the RX_DATA pin. The
transmit-on control (TX_ON) must be deactivated and the
synthesiser (SYNT_ON) activated if data is to be received.
PX_ON
Packet switch on control is active 'high'. Activate this signal
during reception of a Bluetooth payload.
PX_ON is used to control the Dynamic Automatic Frequency
Compensation (DAFC) of the receiver. Since the General
Inquiry Access Code (GIAC), information in a Bluetooth
packet header contains an equal number of one's (+FMOD)
and zero's (-FMOD), the average frequency will always be
centered on the carrier frequency. This provides the DAFC
with the reference for the fast tuning. If the fast mode is not
used during the header then the first bits could be interpreted
incorrectly.
The slow mode gives a more accurate FSK compensation
of the thresholds for a one and a zero compared to the
fast mode; therefore, the BER is less. The fast mode (time
constant <2s) is used when PX_ON is deactived and the
slow mode (time constant <50s) when it is activated.
TX_ON
Transmit-on control is active 'high'. Activate this signal to
enable radio signal output on the ANT pin. The actual transfer
of data that exists on the TX_DATA input occurs when
PHD_OFF goes 'high'. The receive-on control, RX_ON, must
also be 'low' if data is to be transmitted.
