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.
