SiW3000
60 0049 R01Drf SiW3000 Radio Processor DS
Radio Features
•
Direct-conversion architecture with no external IF filter or VCO resonator components.
•
Single ended RF I/O reduces system bill of materials (BOM) costs by eliminating the need to use external balun and
switch circuits.
•
On-chip VCO and PLL support multiple GSM, CDMA, GPRS standard reference clock frequencies.
•
Low out-of-band spurious emission transmitter prevents blocking of sensitive mobile phone RF circuits.
•
No tuning during production.
•
Internal temperature compensation circuit stabilizes performance across wide operating temperature.
•
Fast settling synthesizer reduces power consumption.
•
Up to 100 meter operating range in standard configuration without using an external PA.
Baseband Features
•
ARM7TDMI processor core running at 16 MHz.
•
Digital GFSK modem for maximum performance and lower packet error rate.
•

External System Interfaces
Host HCI Transport (H:2 USB)
The USB device interface provides a physical transport between the SiW3000 and the host for the transfer of Bluetooth
control signals and data. This transport layer is fully compliant with Section H:2 of the Bluetooth specification with all end
points supported. The SiW3000 USB interface encompasses three I/O signals: USB_DPLS, USB_DMNS, and
USB_DPLS_PULLUP. If the USB transport is not used, the USB_DPLS and USB_DMNS pins should be grounded to
reduce current consumption.
