Final Datasheet
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 -1 dBm FSK output signal. The single conversion Low-IF receiver has all the sensitivity and selectively advantages of a traditional superheterodyne without requiring costly, bulky external filters, while providing the integration advantages of direct conversion. The phase locked loop (PLL) synthesizer is completely integrated, including the voltage controlled oscillator (VCO), tuning circuits, and VCO resonator. This allows the ML2722 to be used in frequency hopped spread spectrum (FHSS) applications. The ML2722 contains internal voltage regulation. It also contains PLL and transmitter configuration registers. The device can be placed in a low power standby mode for current sensitive applications. It is packaged in a 32TQFP. § § § § § § § § §
