ML2724

ML2724 2.4GHz Low-IF 1.5Mbps FSK Transceiver Final Datasheet GENERAL DESCRIPTION The ML2724 is a fully integrated 1.5Mbps frequency shift keyed (FSK) transceiver that operates in the unlicensed 2.4GHz 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. Closed loop modulation eliminates frequency drift and permits practically unlimited TX duration. The transmitter generates a 3dBm FSK output signal. The 1.5Mbps data rate permits data spreading, such as Direct Sequence Spread Spectrum (DSSS) modulation, which improves range. The dual conversion Low-IF receiver has all of the sensitivity and selectivity advantages of a traditional super-heterodyne 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 ML2724 to be used in frequency hopped spread spectrum (FHSS) applications. The ML2724 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.
