It allows the control of the output frequency with an input voltage (VCON), using a low cost 12MHz to 25MHz crystal. This one IC can be used to produce a VCXO with output frequencies ranging from FXIN / 16 to FXIN x 32 thanks to the four frequency selector pads. This makes the PL502-30 ideal as a universal die for applications ranging from ADSL to SONET.
