power control Supports Power Class 1 operation with an
external Power Amplifie Outstanding maximum usable input signal Interface with base-band: BlueRF compatible unidirectional received data: RxMode2 and RxMode2+ are
supported serial interface: JTAG CMOS technology Standard VFQFPN-48 package Low standby power consumption Extended temperature range Compliant to automotive specification AEC-Q100
APPLICATIONS Wireless data transmission applications to 432
Kbps symmetrical or 721 Kbps asymmetrical. Typical applications in which the STLC2150 is
used are: Computer peripherals Modems Cameras Portable computers, PDA Handheld data transfer devices Mobile phone Other types of devices that require the wireless
communication provided by Bluetooth®.
DESCRIPTIONThe STLC2150 is a fully integrated Bluetooth® single
chip radio transceiver. Together with a BB processor,
like STLC2410, it offers a compact and complete so-
lution for short-range wireless connectivity for a vari-
ety of applications.
The STLC2150 implements a low-IF receiver for
Bluetooth® modulated input signals and no external
IF filtering is required. The GFSK demodulator is fully
integrated and supplies digital output data and RSSI.
The transmit section features a fully integrated GFSK
modulator, followed by a direct up-conversion stage,
giving an output signal of 0 dBm. Optional power con-
trol is available.
On-chip VCO covers full Bluetooth® band and con-
tains all of the tank resonator circuitry. Unidirectional
BlueRF compatible interface and 4 wires serial JTAG
interface are used to control all functions of radio
transceiver, enabling operation with wide range of BB
processors.

FUNCTIONAL DESCRIPTION
ReceiverThe STLC2150 implements a low-IF receiver for Bluetooth® modulated input signals. The radio signal is taken
from 75Ω balanced RF input and amplified by an LNA.
The mixers are driven by two quadrature signals which are locally generated from a VCO signal running at
twice the frequency. The output signals in the I signal path and Q signal path are bandpass filtered by a
polyphase bandpass filter for channel filtering and image rejection. The output of the lowpass filters is amplified
by a VGA to the optimal input range for the A/D converters.
Further filtering is done in digital filters. The digital part demodulates the GFSK coded bit stream by evaluating
the phase information in the I and Q signals.
The digital part recovers the receive bit clock. It extracts RSSI data by calculating the signal strength. Overall
automatic gain amplification in the receive path is controlled by the digital part.
TransmitterThe transmitter takes the serial input transmit data from the base-band. This data is GFSK modulated to I and
Q signals. The Tx bit clock is provided to the base-band for synchronization.
The output of the digital part is converted to analogue signals which are lowpass filtered before being sent to
direct up-conversion mixers.
The quadrature up-conversion mixers use the same LO as the receiver. 0dBm output power at the antenna port
is achieved with an internal PA, which has 75Ω balanced RF output. Optional power control is available.
PLLThe on-chip VCO is part of a PLL, the frequency is programmed for the RF channels by the digital part. The tank
resonator circuitry for the VCO is completely integrated.
Process variations on the VCO center frequency are calibrated out automatically. Also the RC time constants
for the analogue lowpass filters are automatically calibrated on chip.
Base-band interfaceUnidirectional BlueRF compatible interface is used to control all functions of radio transceiver.
The unidirectional RXMODE2 is supported. STLC2150 has also the capability to provide the recovered clock
and the aligned data to the base-band (Rxmode2+). 4 wires serial JTAG interface is used to access the internal
registers. Also JTAG is used to set channel number and read RSSI.
Crystal oscillatorThe STLC2150 has a crystal oscillator to generate 13 MHz reference clock for internal use and for the base-
band chip.
Also a 3.2 or 32 kHz clock for low power modes operation can be provided.

GENERAL SPECIFICATIONAll the provided values are specified over the operational conditions (VDD and temperature) according to the
Bluetooth® v.1.2 specification.
ReceiverTo comply with the Bluetooth® norm, an external RF filter is required to provide minimum 17dB of attenuation
in the bands: 30MHz - 2000MHz and 3000MHz - 12.75GHz. All specification below are measured at the antenna
port. The loss between IC inputs and the port is approximately 2dB
1) Sensitivity at chip pins is -79.5 dBm.
2) Guarantied over process variation and full temperature range -40 to +85°C.
3) Without any exception.
RSSI ExtractionThe RSSI extraction block allows to determine the Received Signal Strength. The indicator output is an 8-bit
word, indicating the signal strength in dBm
The RSSI value is stored in the RSSI register. The value is latched when the base-band sends the access code
recognition signal (BPKTCTL) and is kept unchanged until the next RX active slot. The register can be read by
the base-band at any time
