LMX5080 PLLatinum™ 2.
7 GHz Low Power Dual Modulus Prescaler for RF Personal Communications
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 Bi
CMOS 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 capacitor...
