Si4133 PLL

There are several implementations of the Si4133 as a LO for Amateur Radio Projects but most rely upon an external 10MHz.    Having a requirement to build several for my transverter projects I embarked on building my own with an integrated OCXO or TCXO.  The oscillator cannot be seen in the photo as it is on the underside of the board to maximize the use of the PCB real estate.
The significant difference this design offers is the on board 26MHz OCXO (or 14.4MHz TCXO)
