5775 MOREHOUSE DRIVE SAN DIEGO, CA 92121
T (858) 658-5005 F (858) 658-1556
Lowpass filtering for CDMA and GPS I- and Q-component baseband
signal demodulation
4-bit ADCs convert CDMA or GPS I and Q analog baseband
components to digital baseband
IF LO circuits include on-chip VCO with selectable frequency divide
ratios (2, 3, 4, 6)
I- and Q-channel DC offset control inputs drive baseband DC voltage
offset to zero in CDMA and GPS signal paths
Selective programming modes to extend handset power savings
MSM-controlled operation via serial bus interface (SBI)
Supply voltage from 2.7 V to 3.0 V
32-pin BCC++ package (5 mm x 5 mm x 0.8 mm)
