General Description
The LMX237X family of monolithic, integrated dual frequency synthesizers, including prescalers, is designed to be used as a first and second local oscillator for dual mode or dual conversion transceivers.
It is fabricated using National’s 0.
5u ABiCV silicon Bi
CMOS process.
The LMX237X contains two dual modulus prescalers.
A 32/33 or a 16/17 prescaler can be selected for the 2.
5 GHz and 2.
0 GHz ...
