Quartz, Oscillators, RTC
This product group contains:
- Crystal Oscillators
- Real Time Clock modules
Crystal (or Quartz Crystal)
Quartz crystal consists of piezo electrical material and applied in oscillator circuitries to create an electrical signal with a very precise frequency.
Crystals can be manufactured for oscillation over a wide range of frequencies from kilohertz up to several hundred megahertz. A variety of frequencies is available in many different packages.
Depending on the frequency quarz crystals are available in CAN – Metal – Plastic – Ceramic packages. THT and SMD derivates suits to the market demand and application requirements.
Oscillator (Active Component with integrated Crystal)
Oscillators became known as crystal oscillators as a crystal is applied to a IC/ amplifiere to provide a clock output signal. 50ppm stability is a industrial standard, available in various
packages down to 2×1,6mm.
Environmental changes like temperature and others can change the frequency of a quartz crystal. Derivates , such as TCXO, VC-TCXO , OCXO or Digial temperatur compensated Oscillators can reduce these environmental effects. Stabilities of 0,02 ppm can be achieved.
SAW Oscillators provide lowest Jitter , high frequeny clocks in TTL- CMOS – LVDS – Differential LV PECL output load conditions.
Real Time Clock modules (Active Component with integrated Crystal)
…Goes without saying…
Space saving: all in one package Time saving: no further evaluation , “ finished product”
Power saving. Lowest current consumption Reliability: save oscillation start , low failure rate
