Part Details:

LMX9402 PRELIMINARY October 2000 LMX9402 Frequency Frequency Synthesizer Module General Description The module is available in a Ball Grid Array 560 mil X 560 milX 220 mil package. The Frequency Synthesizer Module is a Low TemperatureCo-fired Ceramic (LTCC) RF module consisting of a high Features Synthesizer performance frequency synthesizer, loop filter, and voltagecontrolled oscillator (VCO). The frequency synthesizer is n Low phase noise tunable local oscillator fabricated using National s ABiC BiCMOS process (f = 14 T n Low current consumption GHz). The loop filter and VCO are fabricated on National s n LMX2330A 2.5 GHz PLLatinumTM in module Low Temperature Co-fired Ceramics. The Frequency Synthesizer Module can be used for local Applications oscillator applications. Using a digital phase locked loop n DCS wireless cellular systems technique, the on board frequency synthesizer can generate n Fixed wireless communications a very stable, low noise local oscillator. Serial data is trans- Module ferred into the module using a three wire interface. The loopfilter is designed for fast lock times and maximum attenua-tion of reference spurs.
