The Tondelayo Baseband SBB1001 is part of the Tondelayo chipset,
which implements a complete wireless LAN (W-LAN) subsystem
for 2.4 GHz and 5 GHz frequency bands. This chipset makes
it possible to create a low-cost, highly integrated, programmable
W-LAN subsystem, which can be integrated both in mobile terminals
and base stations. Switching between IEEE 802.11a and 802.11b
is performed in the field simply by loading the corresponding
firmware transparently to the user. Delivered in a small footprint
package (µBGA176) and equipped with smart power save
modes, the Tondelayo Baseband SBB1001 helps cut costs and
power dissipation for high performance W-LAN products.
Fully compliant with the IEEE 802.11a 5 GHz and 802.11b
2.4 GHz standards.
Based on Systemonic's OnDSP™ signal processing engine.
Complete physical layer.
Processing of time-critical functions within the 802.11
MAC layer (DCF, NAV calculations, error handling, RTS/CTS
mechanism, CRC calculations, retransmission handling, etc.).
Smart standby features for power savings.
Data rates up to 54 Mbps.
Full digital synchronization (time, frequency, and phase).
Hardware accelerators for channel encoding/decoding and
receive and transmit filters.
Digital Rx and Tx filtering for increased adjacent channel
performance and spectrum shaping.
On-chip high performance 10 bit analog-to-digital and
digital-to-analog converters.
Analog and digital gain control for the RF front end.
Support for Receive Signal Sensitivity Indicator (RSSI).
