ORDERING INFORMATION

WL800/KG/TP1R

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.
