Need for frequency and phase sync
Mobile systems are based on cell based architecture,each cell (called Base (transceiver) station or Node-B)covering a specific area and connected to a centrallocation (Called RNC)
Frequency accuracy limit and phase error limit isrequired to support
Support exact cell frequencies for better network design
Handle the effect of doppler shifts of moving mobile units
Manage the handover of moving mobile units from one basestation
Support broadcasting of video and other multimedia content

Rakon - Key technical strengths
Linearity of voltage control
To ensure the compensation remains perfect at any VCXO Voltage
Patented 3rd order polynomial varactor linearisation circuit (also knownas the Pre-distort function)
linearises the frequency control for both compensation and VCXO (aging)adjust voltage
Completely unique feature
Best F v T performances For various stability requirements
Excellent phase noise performance The device can directly drive the radio interfaces
Low Power consumption 400mW vs 1.5-2W in conventional OCXO; key in PoE

Patented 3rd order polynomial varactor diode linearisation circuit
The relationship between varactor voltage and varactor capacitance is linearised
In practice this means that as a RAKON TCXO ages and is adjusted back to frequency using
the Vc pin, its frequency versus temperature remains in specification and does not tilt (see
figure 1 below)
Other manufacturers TCXOs can go out of specification with timeRakons do not
