Features
• Single chip IC with 2.4 GHz
transceiver and GFSK modem with
digital interface to external baseband
processor.
• Fully compliant with Bluetooth
specification 1.1 and 1.2.
• Supports multiple external reference
clocks or crystal frequencies with on-
chip reference PLL.
• Direct-conversion architecture with
no external channel filter or VCO
resonator components.
• Single-ended RX/TX pins reduce
system BOM cost by eliminating a
balun. On-chip RX/TX switching
eliminates external RX/TX switch.
• Typical -85 dBm receiver sensitivity
with excellent interference rejection
performance.
• Class 2 and 3 transmit output power
up to +4 dBm with output power
control loop for accurate power
control.
• Hardware AGC dynamically adjusts
receiver performance in changing
environments.
• Low out-of-band spurious emissions
prevents interference with mobile
phone frequencies.
• Option for Class 1 designs with
RX/TX switch control and multiple
modes of gain control.
• On-chip voltage regulation simplifies
voltage input requirement. Regulator
bypass mode enables use of external
regulator.
• 1.8 Volt analog and digital core
voltages; 1.63 Volt to 3.63 Volt
external I/O interface voltage.
• Low power consumption in active and
standby modes.

Product Description
The SiW1711™ Radio Modem is Silicon Wave's third-generation radio modem for
Bluetooth® wireless communications and is based on 0.18µm CMOS technology. This
highly integrated transceiver was specifically designed to meet the rigorous RF perfor-
mance required for integrating Bluetooth into mobile phone applications.
The SiW1711 Radio Modem combines a 2.4GHz radio transceiver and Gaussian Fre-
quency Shift Keying (GFSK) modem with digital control functions. The IC also incorpo-
rates analog and digital voltage regulators, a reference Phase Lock Loop (PLL) to
enable multiple input frequencies, and a power-on-reset (POR) circuit.
The SiW1711 Radio Modem uses direct conversion (zero-IF) architecture. This allows
digital filtering for excellent interference rejection as compared to low IF solutions, and
also results in fewer spurious responses. The receiver has excellent sensitivity due to a
low noise RF design combined with an advanced modem design. A fast hardware AGC
enables full discovery of any device within the dynamic range of the receiver (solves
near-far issues). The transmitter can maintain a stable output power level up to +4dBm
for class 2 operation, which in combination with the excellent receiver performance
ensures the maximum possible range at the lowest system cost.
The device is available in a 32-pin QFN package with 5 x 5 x 1 mm dimensions. Known
good die with bumps is also available. Operating temperature range is guaranteed from
-40°C to +85°C with available extended high temperature range to 105°C.
