Web Exhibition

TG-5500CA　*Frequency/temperature coefficient of ±0.1 × 10-6 *Satisfies Stratum 3 aging requirements *Maximum 4 mA consumption *Equipped with a QMEMS photo AT chip

Point! A frequency/temperature coefficient of ±0.1 × 10-6 is typically found in OCXO, but we were able to produce a TCXO with the same coefficient using our QMEMS technology. The simpler structure of TCXO means the TG-5500CA consumes about 1/40th the current of existing OCXO, making it very eco-friendly!

OCXO stability, TCXO consumption

The figure below shows that we have been able to produce a ±0.1 × 10^-6 TCXO for use in high-stability clock applications that OCXO are currently used for. Consuming only 4 mA – approximately 1/40th the current of an OCXO – the TG-5500CA makes it possible to produce more eco-friendly network equipment.

OCXO-level stability, yet with far less current consumed!

Sample applications

Femtocell base stations, low-power Stratum 3 server applications, etc.
