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
