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 -40C to +85C. Applications * Mobile phones with integrated controller for Bluetooth wireless technology.

During the receive process, the radio signal is taken from the single-ended RF input pin that feeds into the low noise amplifier (LNA). The signal from the LNA is directly down-converted to I/Q baseband, filtered with an anti-aliasing filter, and converted to a digital signal with a high resolution analog-to-digital converter. The critical channel filtering is done in the digital domain for stable and repeatable performance. The signal is then processed by a high performance GFSK demodulator. The IC has multiple internal selfcalibration circuits to maintain stable and repeatable performance from part-to-part as well as over the full temperature range. The IC has two fully integrated regulators: one for the radio (analog regulator) and one for the digital logic (digital regulator). The digital regulator can be used to supply a Bluetooth baseband controller. Both regulators can be bypassed if external regulation is desired. Note: When bypassing the analog regulator, the VBATT_ANA and VCC_OUT pins must be tied together and the external analog voltage (1.8 V) should be applied to the VBATT_ANA pin. When bypassing the digital regulator, the VBATT_DIG pin should be left unconnected and the external digital voltage (1.8 V) should be applied to the VBB_OUT pin. The IC also provides power on reset and glitch-free clock start-up. A reference PLL can be enabled to support a number of different reference frequencies. Digital control functions and a programming interface provide radio modem control and a flexible interface to external Bluetooth link controllers.

This means predictable and repeatable range at any temperature. Modem Interface The modem interface transfers the Bluetooth data between the SiW1721B Radio Modem and the ASIC. For reference purposes, the pin description table (Table 1) provides a brief description of typical interface modes. Clock Signals Multiple reference clock frequencies can be used as a reference for the RF circuits, to synthesize clocks for most of the internal digital circuits, and to supply external processors with timing signals. Serial Programming Interface (SPI) The serial programming interface (SPI) is used to access the internal registers of the SiW1721B Radio Modem. The SPI is a synchronous serial interface that can be clocked to a nominal speed of 8MHz. Power The SiW1721B Radio Modem includes both analog and digital voltage regulators. Input options are based on factors such as voltage source, where internal regulators are used, and I/O voltage. 2 of 12 60 0076 R00F SiW1721B Radio Modem IC DS VCC SiW1721B Pin Description The SiW1721B Radio Modem's radio and modem interface (SPI), a single clock input, and supply voltage are required for proper operation.

The pocket is designed to hold the part for shipping and loading onto SMT manufacturing equipment, while protecting the body and the solder terminals from damaging stresses. The individual pocket design can vary from vendor to vendor, but width and pitch will be consistent. Carrier tape is wound or placed onto a shipping reel either 330 mm (13 inches) in diameter or 178 mm (7 inches) in diameter. The center hub design is large enough to ensure the radius formed by the carrier tape around it does not put unnecessary stress on the parts. Prior to shipping, moisture sensitive parts (MSL level 2a-5a) are baked and placed into the pockets of the carrier tape. A cover tape is sealed over the top of the entire length of the carrier tape. The reel is sealed in a moisture barrier ESD bag, which is placed in a cardboard shipping box. It is important to note that unused moisture sensitive parts need to be resealed in the moisture barrier bag. If the reels exceed the exposure limit and need to be baked, most carrier tape and shipping reels are not rated as bakeable at 125C. If baking is required, devices may be baked according to section 4, table 4-1, column 8, of the Joint Industry Standard IPC/JEDEC J-STD-033A.
