11 / 14 page – 11 – CXA3329ER Notes on Operation 1. Baseband signal I/Q input Pins 3 to 6, where the baseband signal is input, do not have a determined voltage internally on the IC. Therefore, a bias voltage equivalent to 1/2VCC should be applied externally. 2. IF signal output The IF signal outputs, OUT/OUTX, are differential outputs. The output impedance should be 1k Ω including the external resistance with differential. Also, it is necessary to connect the inductor to eliminate the parasitic capacitance in the IC. 3. Notes on power supplies The CXA3329ER is designed to operate by a 2.85V stabilized power supply to allow use with the battery driven portable phones. Using the multiple voltage regulators throughout the phone is recommended to minimize the power supply noise in the CXA3329ER power supply unit. The recommended power supply range for the CXA3329ER is from 2.7V to 3.3V. Decouple the power supplies around the CXA3329ER using 1µF capacitor for each VCC pin. Locate this capacitor as close to the pins as possible to minimize the series inductance. Using an additional 1nF decoupling capacitor in parallel to the 1µF capacitor is recommended to further reduce the high frequency noise in the power supply input to the CXA3329ER. |
