• CRYSTAL UNIT
It is commonly referred to as a quartz oscillator, which is an electrode attached to a quartz crystal cut from a specific angle of natural or artificial crystal. TVs, VCRs, watches, electronic calculators, PCs and the like. Recently, it is widely used in mobile communication such as mobile phones, pagers, and PCS. HC-49 / U, HC-49 / US, UM-1, UM-4 and UM-5.
Generally, it is called a crystal oscillator and incorporates an oscillation circuit that controls the oscillation frequency using a crystal oscillator. It is a frequency generation source that supplies a stable frequency and is used in various electric telecommunication devices, measuring instruments, PCs and the like.
It has a built-in oscillation circuit like oscillator and it has a difference that output frequency changes by controlling voltage. It is mainly used for mobile communication, image control, PLL and the like.
It is one of the modified products and it compensates the inherent temperature characteristic of crystal by using parts such as thermistor to reduce the error of output frequency. It is mainly used for CDMA terminal, PCS .
This product is the reverse use of the property that the crystal changes sensitive to temperature. Oven is used to keep the temperature around the crystal constant, so that there is no error. It is the most precise but the bulky, One product generally uses a single power source such as 3.3Volt or 5Volt, but uses various power sources such as 12V
