IDTCV133PAG

IDTCV133PAG Application Field and Working Principle

The IDTCV133PAG (Integrated Device Technology CV-133PAG) is a voltage-controlled, non-programmable, temperature compensated SMBus oscillator (VCTCXO), which primarily finds applications in battery-operated products where good system synchronization and/or timing accuracy is critical and/or power consumption needs to be minimized. In particular, it is often used in products related to the Smart Grid or the Internet of Things (IoT) for applications such as energy management, home automation, or smart cities.

The IDTCV133PAG is manufactured using the company’s proprietary high technology, allowing for the delivery of superior performance with low power consumption. It is a low-jitter, low-phase noise VCTCXO that is capable of operating over an extended temperature range, from -10 to +70C, making it ideal for industrial and automotive applications. It also supports a frequency range from 25.1 MHz up to 76.8 MHz, with a frequency tolerance of +/- 50ppm.

The working principle of the IDTCV133PAG is based on voltage-controlled oscillator technology. In this type of oscillator, an external control voltage is supplied to a VCL circuit, which is modulated by changing frequencies to generate a system clock signal. The VCL circuit is then fed into a voltage-controlled resonator (VCXO), which is responsible for generating the fundamental clock frequency. The VCXO output is then processed by a temperature-compensated high-stability circuit, which is used to control the frequency accuracy and long-term stability of the clock signal, ensuring that the system clock performs reliably over time even under extreme environmental conditions.

The IDTCV133PAG includes an internal low-jitter clock buffer that provides a low-noise clock signal to downstream components of the system. The VCXO also features a low-power consumption design and fast start-up time, reducing the overall power consumption of the device. Additionally, an SMBus port allows the VCTCXO to be controlled through an integrated communication interface, enabling it to be used as a very accurate and reliable system clock in applications dependent on fast, low-power and low-noise clocks.

In summary, the IDTCV133PAG provides manufacturers with high-performance and low-power VCTCXO technology that can be used in battery-operated products where timing accuracy and power efficiency are essential. With its wide frequency range and temperature compensation, it is ideal for industrial and cellular applications, as well as for energy management and home automation systems. Furthermore, thanks to its integrated clock buffer and fast start-up time, the VCTCXO can provide a low-noise clock signal with reliable long-term stability, making it an extremely reliable clock source for system synchronization.
