Brief
65-nm CMOS DigRF EDGE CELLULAR TRANSCEIVER
FEATURES
SUMMARY OF BENEFITS
• Quad-band CMOS EDGE/GPRS RF transceiver
• Supports multislot GPRS and EDGE operation up to Class 34
• Innovative polar transmit architecture
• GMSK and 8-PSK TX modulators and ramp DAC
• Four integrated receive LNAs
• Digital low-IF receive architecture including digital filter
• Σ∆ ADCs for conversion of baseband receive signal
• Fully integrated Σ∆ fractional-N synthesizer including VCOs
and loop filters
• Integrated digitally-controlled crystal oscillator (DCXO)
• DigRF compatible (v1.12) baseband interface
• Autonomous, real-time radio calibration
• Compact 49-pin FBGA package (4 mm × 4 mm)
• Advanced 65-nm standard digital CMOS design for lowest
power consumption
• Highly integrated design enables lowest cost, smallest area
DigRF EDGE solution
• Polar transmitter architecture for EDGE enables use of
standard linear power amplifiers to simplify
• No SAW filters in the transmit path
• No baseband intervention required for radio calibration
APPLICATIONS
• Mobile handsets and smartphones
