The Systemonic Tondelayo 1 dual-band
chipset offers a truly differentiated product that provides
users with multi-protocol options for operating in various W-LAN
environments. The Tondelayo 1 Baseband has at its core a DSP
architecture that is optimized to manage tradeoffs between power
dissipation and processing capacity. The Tondelayo RF chips
are designed to support W-LAN solutions in the 2.4 GHz and 5
GHz frequency bands. The combined chipset makes for a solution
that affords transparent connectivity, facilitating seamless
roaming for the mobile user. Tondelayo 1 enables wireless LAN
communications at up to 54 Mbps according IEEE 802.11a, in addition
to providing backward compatibility to an installed base of
802.11b-compliant systems.
Support for both 2.4 GHz and 5 GHz frequency bands is
accomplished using the same chipset.
In field selectable 802.11a and 802.11b operation provides
seamless roaming between legacy 2.4 GHz and the new 5 GHz
wireless LAN networks provides seamless “detect and
connect” roaming.
Programmable architecture enables easy differentiation
from competitors.
Supporting latest wireless technology increases product
life cycles and protects customers’ investment.
On-chip memory and flexible interfaces reduce overall
system bill of material.
Low risk, superheterodyne front-end architecture keeps
frequency synthesis off-chip for maximum system flexibility.
Receive gain split between RF and IF chips minimizes layout
and oscillation problems.
Front-end Input and output impedances are matched on-chip
for easy integration with external components.
Advanced SiGe process for the front-end chipset provides
improved linearity and lower phase noise contributing to
a longer range.
Smart power save modes provides for longer battery life
in mobile devices.
Suitable for both access points and client terminals.
