Summary
The SiW1721B is a 2.4-GHz radio transceiver for Bluetooth wireless
technology. This highly integrated transceiver is specifically designed for use
with a third party Bluetooth baseband controller chipset requiring an
external Bluetooth RF transceiver. Due to its low power CMOS process, the
design minimizes current draw in both active and standby modes.
The SiW1721B combines a radio transceiver and Gaussian Frequency Shift
Keying (GFSK) modem with digital control and interface logic. The IC also
incorporates analog and digital voltage regulators and a reference Phase
Lock Loop (PLL) capable of accepting various reference clock frequencies.
The level of integration enables a low system cost with fewer external
components.
The SiW1721B is packaged in a 5-by-5-mm, Pb-free, 32-pin QFN package
that meets RoHS (Green) requirements. Operating temperature range is
guaranteed from -40°C to +85°C.
Applications
• Mobile phones with integrated
controller for Bluetooth wireless
technology.
