GENERAL DESCRIPTION
The ML2722 is a fully integrated 1.5Mbps frequency shift keyed (FSK) transceiver that operates in the unlicensed 900MHz ISM frequency band. The device has been optimized for digital cordless telephone applications and includes all the frequency generation, receive and transmit functions. Automatically adjusted filters eliminate mechanical tuning. The transmitter generates a -1dBm FSK output signal. The single conversion Low-IF receiver has all the sensitivity and selectively advantages of a traditional super heterodyne without requiring costly, bulky external
filters, while providing the integration advantages of direct conversion.
