ECS-400-8-48-RTN-TR

Crystals provide an important connection between the physical and digital domains in a variety of applications. A particularly important type of crystal is the ECS-400-8-48-RTN-TR, a versatile component that can be used to generate precise time intervals or precise reference frequencies. The design and operation of this crystal makes it a useful component for many applications, particularly in the communication and timing systems used in mobile and embedded applications.

The ECS-400-8-48-RTN-TR is a network-timing crystal from ECS Inc., part of the company’s Timely Timing portfolio of oscillator and crystal-based timing solutions. The component consists of a custom-made temperature-compensated quartz crystal (TCXO) housed in a metal can package. It is designed to provide precise and accurate timing solutions for resonator-crystal lattice filters and for timing applications requiring a high frequency range. The component also features excellent performance over temperature variation.

The component is specifically used in network-timing applications, primarily as a medium-format frequency reference or as a “glue” component linking the devices in a larger communications network. For such purposes, the component must maintain precise timing to within a few microseconds over a range of temperatures, from -40°C to +185°C. To achieve this, the quartz crystal oscillator (QCO) within the component is temperature-compensated, using a proprietary circuit design for superior stability.

The ECS-400-8-48-RTN-TR crystal operates in the 8 to 48 MHz frequency range. To achieve this frequency range, the component is mounted in a ceramic package with a high-stability ceramic-resonator material, which is combined with a highly efficient high-temperature dielectric and resonating electrodes. This combination allows the component to achieve a high frequency range with high oscillating accuracy. The component is also RoHS-compliant and offers precision quartz oscillators with a -40°C to +85°C operating temperature range.

In operation, the ECS-400-8-48-RTN-TR operates using an oscillation circuit. This circuit employs a common crystal frequency source (CSFS) to produce a signal that is then amplified by the oscillator circuit. The frequency of the signal is determined by the vibration of the resonator crystal in the component. The signal is then fed into the chip’s resonator-crystal lattice filter for further amplification and refinement before being passed to the device’s digital processor.

The use of a crystal resonator provides a number of advantages, including excellent energy efficiency, low cost, high frequency range, and precise and accurate timing. The ECS-400-8-48-RTN-TR crystal is an ideal choice for timing applications, such as communication and cellular systems, smart watches, timepieces, and industrial control systems, where precise, accurate timing is essential.
