LMX5080 PLLatinum 2.7 GHz Low Power Dual Modulus Prescaler for RF Personal munications PRELIMINARY April 1999 LMX5080 PLLatinum™ 2.7 GHz Low Power Dual Modulus Prescaler for RF Personal munications General Description The LMX5080 integrated dual modulus prescaler, is designed to be used in a synthesized local oscillator for 2.5 GHz wireless transceivers. It is fabricated using National’s 0.5µ ABiCV silicon BiCMOS process. The LMX5080 contains three dual modulus prescalers. Either a 128/130, 256/158 or a 512/514 prescaler can be selected for up to 2.7 Gz RF input frequencies. The prescaler inputs can be driven either differentially, or single ended with the use of a coupling...
