GENERAL DESCRIPTION
The ADF4217L/ADF4218L/ADF4219L are low power dual frequency synthesizers that can be used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. They can provide the LO for both the RF and IF sections. They consist of a low noise digital PFD (phase frequency detector), a precision charge pump, a programmable reference...
