BC41B143A-ds-002Pd
Common TX/RX terminals simplify external
matching and eliminates external antenna switch
BIST minimises production test time. No external
trimming is required in production
Full RF reference designs are available
Bluetooth v2.0 + EDR Specification compliant
+6dBm RF transmit power with level control from
on-chip 6-bit DAC over a dynamic range >30dB
Class 2 and Class 3 support without the need for
an external power amplifier or TX/RX switch
Class 1 support using external power amplifier, with
RF power controlled by an internal 8-bit DAC
Supports DQPSK (2Mbps) and 8DPSK (3Mbps)
modulation
Integrated channel filters
Digital demodulator for improved sensitivity and co-
channel rejection
Real-time digitised RSSI available on HCI interface
Fast AGC for enhanced dynamic range
Supports DQPSK and 8DPSK modulation
Channel classification
Fully integrated synthesizer requires no external
VCO varactor diode, resonator or loop filter
Compatible with crystals between 8 and 40MHz (in
multiples of 250kHz) or an external clock
Accepts 7.68, 14.44, 15.36, 16.2, 16.8, 19.2, 19.44,
19.68, 19.8 and 38.4MHz TCXO frequencies for
GSM and CDMA devices with sinusoidal or logic
level signals
Crystal oscillator with built-in digital trimming
Power management includes digital shut down and
wake up commands with an integrated low-power
oscillator for ultra-low Park/Sniff/Hold mode
Clock Request output to control an external clock
source
