Description

The ML2722EH is a fully integrated 1.5Mbps frequency shift keyed (FSK) transceiver that operates in the unlicensed 900MHz ISM frequency band. It has been optimized for digital cordless telephone applications and includes all the necessary functions for frequency generation, receive, and transmit. The device features automatically adjusted filters, eliminating the need for mechanical tuning. The transmitter generates a -1dBm FSK output signal, while the single conversion Low-IF receiver offers the sensitivity and selectivity advantages of a traditional super heterodyne without the need for bulky external filters.
