ML2724  
2.4GHz Low-IF 1.5Mbps FSK Transceiver  
Final Datasheet  
GENERAL DESCRIPTION  
FEATURES  
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.  
ꢀ
Complete 2.4GHz FSK Transceiver  
- High data rate (1.5Mbps)  
- -90dBm sensitivity (DSSS modulation)  
- 3dBm Output Power (differential, typical)  
Closed Loop TX Modulation  
ꢀ
ꢀ
ꢀ
Low IF Receiver: No external IF filters required.  
Fully Integrated frequency synthesizer:  
- No external resonator required.  
Sigma-Delta Fractional-N two-port modulator  
Automatic Filter Alignment  
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.  
ꢀ
ꢀ
- No manufacturing adjustments required.  
No external data slicer components required  
Control outputs correctly sequence and control PA  
3-wire control interface  
ꢀ
ꢀ
ꢀ
ꢀ
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.  
Analog RSSI output  
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.
