GENERAL DESCRIPTION
The UAA3559HN BiCMOS device is a low-power, highly
integrated circuit. It features a fully integrated receiver for
demodulating the output signal from an external antenna
filter, an integrated VCO, a synthesizer to implement
Bluetooth channel frequencies, and a transmitter
preamplifier. The output power of the transmitter
preamplifier can be programmed in eight steps from
7.5 dBm to +9 dBm (typical) and drives either an antenna
via an external switch diode or an external power amplifier.
(1) The Bluetooth trademarks are owned by Bluetooth SIG, Inc.,
U.S.A. and licensed to Koninklijke Philips Electronics N.V.
The synthesizer comprises a reference divider, main
divider with prescaler, and a phase comparator. The
division ratios of both dividers are programmed by control
signals on a 3-wire bus. The main divider accepts a
frequency range of 2402 MHz to 2481 MHz from the
internal VCO. The reference divider accepts either a
12 MHz or 13 MHz signal from an external crystal
oscillator. The outputs of both dividers are compared by a
phase comparator. A charge-pump in the comparator
produces a current pulse output whenever a phase error
occurs. The current pulse output signal controls and phase
locks the VCO frequency. The charge-pump current
(phase comparator gain) is set to 4 mA.
After the synthesizer is programmed, it is activated about
200 µs before the required channel time slot to allow time
for the VCO to lock to the channel frequency. The
synthesizer is then deactivated just before the desired slot
to allow open loop modulation of the VCO in transmit
mode. The synthesizer is also deactivated just before the
desired slot in receive mode. This is required to reduce
power consumption and allows adjustment of the VCO by
an internal carrier follower circuit to maintain an
accurate IF.
The IC is designed to operate from 3.0 V nominal supplies.
Separate power pins are provided for different parts of the
circuit. The ground pins should be connected together
externally to prevent large, potentially harmful, currents
flowing through the IC. All supply pins must be at the same
potential.
