2.5GHz Frequency Synthesiser

The WL800 is a low power single chip frequency synthesiser. The circuit is fabricated on Zarlink Semiconductor HG process and operates from a supply voltage of 2.7 - 3.6V. It is designed to work with the Zarlink 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.
