APPLICATIONS
2400 to 2497 MHz Bluetooth radio transmission and
reception in the Industrial Scientific and Medical (ISM)
band.
GENERAL DESCRIPTION
The UAA3558 BiCMOS device is a low power, highly
integrated circuit. It features a fully integrated receiver,
from antenna filter output to the demodulated data output,
UAA3558
an integrated VCO, a synthesizer to implement Bluetooth
channel frequencies, and a transmitter preamplifier to
drive either the switch diode to antenna or a power
amplifier.
The synthesizer’s main divider is driven by the prescaler
output in the range of 2400 to 2497 MHz and programmed
via a 3-wire serial bus. The reference divider ratio can be
programmed to 12, 13, 16 or 26. Outputs of the main and
reference dividers drive a phase comparator, where a
charge pump produces phase error current pulses for
integration in an external loop filter. The charge-pump
current (phase comparator gain) is set to 3.5 mA.
The synthesizer is programmed and switches on 200
µs
before the desired slot to lock the VCO to the required
channel frequency. Just before the desired slot, the
synthesizer is switched off, allowing open loop modulation
of the VCO during transmission.
The device is designed to operate from 3.0 V nominal
supplies. Separate power and ground pins are provided to
the different parts of the circuit. The ground leads should
be connected together externally to prevent large currents
flowing across the IC, which would cause damage. All
V
CC
pins must also be at the same potential (V
CC
).
