Bluetooth Subsystem Using the SiW1721B Radio Modem
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.

Carriers
Tape and Reel
SiW1721BFIG, 5 X 5 mm, 32-Pin QFN, Tape and Reel Details
Carrier tape basic dimensions are based on EIA 481. 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 125°C. 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.
The following tables provide useful information for carrier tape and reels used for shipping the devices described in this
document.
