WL800
2.5GHz Frequency Synthesiser
Preliminary Information
DS4583 1.6 October1997
The WL800 is a low power single chip frequency synthesiser.
The circuit is fabricated on Mitel Semiconductor HG process
and operates from a supply voltage of 2.7 - 3.6V. It is designed
to work with the Mitel Semiconductor WL600C RF and IF
circuit and the WL102 WLAN controller chip which together
make up the DE6038 frequency hopping Wireless Local Area
Network (WLAN) transceiver.
