JGHC provides a large variety of different Simple Packaged Crystal Oscillators & SAW Oscillators with various sizes, frequencies, OE/ST functions, and temperature ranges for every application. SPXO delivers excellent frequency stability without the necessity of temperature compensation and frequency control. Housing crystal units that consist of AT or BT cut fundamental or overtone and their oscillation circuit in the same package, our crystal clock oscillators are designed and manufactured to provide a stable output of signals when the set voltage is applied. Generally, when customers buy crystal units and use them in their oscillation circuits, they first need to provide analog settings prior to the installation. These include the settings of load capacitance, oscillation allowance, and variations in characteristics due to temperature changes. With JGHC crystal clock oscillators, these settings are already provided by us, so their output signals can directly control TTL and CMOS
