• 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)
