SUPPLY VOLTAGE / LONG TERM AGEING CODE
frequency stability expressed in ppm, either as indicates the supply voltage value in Volts for models offering different
an overall tolerance or as temperature options of supply voltage for (VC)-TCXO
stability only. indicates long term ageing for surface mount PXO
