1 / 25 page ML2726 2.4GHz Low-IF 2.0Mbps FSK Transceiver Preliminary Datasheet OCT 2007 EDS-105982 REV P01 GENERAL DESCRIPTION The ML2726 is a fully integrated 2.0Mbps 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 2.0Mbps 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 ML2726 to be used in frequency hopped spread spectrum (FHSS) applications. The ML2726 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 “Green” Pb-Free 32TQFP.
