Long wanem, ol 'conventional crystal oscillators' i save kisim bikpela hevi long 'ambient temperature', na ol 'oven-controlled crystal oscillators' i bikpela na i no gat planti pawa, olsem na ol 'temperature-compensated crystal oscillators' em i gutpela rot bilong mekim wok long namel -presisen aplikesen. Ol dispela 'oscillator' i save givim 'frequency stability' insait long 10-6 i go inap 10-6 na ol i save wok yet maski ol i putim pawa long en. Long ol yia i go pinis, 'temperature-'teknoloji i kamap hariap na yusim bilong en i kamap bikpela tru.
