2 GHz 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 BiCMOS process.
The LMX237X contains two dual modulus prescalers.
A 32/33 or a 16/17 prescaler can be selected for the 2.
