TS11DF23CDT

Application Field

TS11DF23CDT (Device Type: Thales TS11DF23CDT Crystal) is a low essential delay crystal oscillator intended for timing applications in communications, instrumentation, and aerospace. It is made from the very best quartz elements that make the device extremely dependable, thus ideal in systems with uncompromising demand for accuracy.The TS11DF23CDT provides excellent phase noise performance and stability over an extensive temperature range, thanks to its optimized structure and superior quality in manufacturing processes. It can be used to enhance signal-to-noise ratio and reduce power consumption in EDGE and CDMA receivers. This device offers an high frequency response and supports burst-mode control.

Working Principle

The TS11DF23CDT works on the principle of a Quartz Crystal Oscillator (XO). A quartz crystal exhibits piezoelectric properties, meaning when stressed, it produces a voltage and when subjected to a voltage, the crystal will produce a strain.The crystal is housed in a metal case that helps to protect the crystal from a physical environment. The metal casing is usually hermetically sealed with a lid and connected to a printed circuit board via a pair of terminals. The enclosure also allows for a temperature monitoring circuit and a feedback signal. At the heart of the TS11DF23CDT, lies a quartz crystal that vibrates under the influence of an electrical signal. This signal includes a small amount of energy with a frequency in the range of 20–200MHz, depending on the characteristics of the crystal. The TS11DF23CDT is designed to operate at around 23MHz frequency range.The signal is then amplified and filtered to remove the harmonics, making the signal more stable and easier to control. This signal is then sent to the feedback circuit, which is used to maintain the frequency accuracy of the oscillator. The feedback circuit maintains a constant voltage to the crystal, allowing it to remain stable in varying environmental conditions.
