Epson 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 Epson's crystal clock oscillators, these settings are already provided by us, so their output signals can directly control TTL and CMOS ICs. This shortens design processes for customers and contributes to standardizing parts to be used. Our crystal clock oscillators also feature a VCXO function and a Try-state function. The VCXO function enables control of output frequencies with external control voltage, whereas the output enable feature maintains the output terminals at high impedance levels by outputting signals with control signals while the power is supplied.
