CS-101564-DSP12
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 v2.1+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
Class1 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 synthesiser requires no external
VCO, varactor diode, resonator or loop filter
Compatible with an external crystal or with an
external clock using sinusoidal or logic-level signals
Accepts frequencies between 8 and 32MHz (in
multiples of 250kHz); additionally accepts 7.68, 14.4,
15.36, 16.2, 16.8, 19.2, 19.44, 19.68, 19.8 and
38.4MHz TCXO frequencies typically used in GSM
and CDMA devices
Crystal oscillator with built-in digital trimming
Power management includes digital shutdown, and
wake up commands with an integrated low-power
oscillator for ultra low Park/Sniff/Hold mode
Clock request output to control external clock

Bluetooth Stack
CSR's Bluetooth Protocol Stack runs on the on-chip MCU
in a variety of configurations:
Package Options
On-chip linear regulator; 1.8V output from a 2.2 - 4.2V
input
Clock for low power mode can be either supplied from
an external 32kHz clock signal or an internal
oscillator
Auto Data Rate setting for different TCXO
frequencies
Power-on-reset cell detects low supply voltage
Aribitrary power supply sequencing permitted
8-bit ADC and DAC available to applications
Internal 48-Kbyte RAM, allows full-speed data
transfer, mixed voice and data, and full piconet
operation, including all medium rate preset types
Logic for forward error correction, header error
control, access code correlation, CRC, demodulation,
encryption bit stream generation, whitening and
transmit pulse shaping. Supports all Bluetooth v2.1 +
EDR features including eSCO and AFH
Transcoders for A-law, µ-law and linear voice from
host and A-law, µ-law and CVSD voice over air
Synchronous serial interface up to 4Mbits/s for
system debugging
UART interface with programmable baud rate up to
3Mbits/s with an optional bypass mode
Full-speed USB v2.0 interface supports OHCI and
UHCI host interfaces
Synchronous bi-directional serial programmable
audio interface
Optional I
