Download the ADF4219L datasheet PDF. This datasheet also includes the ADF4217L variant, as both parts are published together in a single manufacturer document.

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 div
