AVX is offering a Kyocera crystal matching service to customers free of charge at its design centre in Fleet, Hampshire. 

The centre will evaluate customer circuit boards and provide technical advice on crystal matching and offer a crystal matching service. 

Crystal matching is the process of fine-tuning an oscillator circuit to obtain optimal performance under operative conditions. 

Oscillator circuits contain both a quartz crystal and an IC which requires a very precise signal generated by the crystal to perform its function accurately. 

Capacitors and resistors are usually necessary to fine-tune the circuit, as six key parameters need to be satisfied: negative resistance, third overtone negative resistance, initial frequency deviation, load capacitance, drive level and start-up time.
