Clock/Timing technology has become increasingly important in today\'s electronics industry, with core devices such as clock generators, PLLs, and frequency synthesizers playing a rapidly growing role. The 1526GLFT is one such example, a frequency synthesizer designed to cater to the needs of a variety of applications. In this article, we will look at the application field and working principle of the 1526GLFT.

The 1526GLFT is a frequency synthesizer built with a fast switching and low jitter clock generator. It operates from a single 2.5 V to 3.3 V supply, offering an input frequency range of 50-158 MHz, and an output frequency range of 10-360 MHz. The device includes a wide range of features, such as a programmable output clock enable/disable option, a programmable output enable/disable, and a programmable output reference clock. It also features differential outputs, allowing users to vary the output power to support a variety of applications.

The device is ideal for use in a number of digital applications, such as digital-to-analog and analog-to-digital converters, clock synchronization, and high-speed communication systems. The wide range of frequencies available makes it suitable for both low-frequency and high-frequency applications, while the low jitter clock generator ensures high accuracy and control. It can also be used as a jitter cleaner in communication systems, and as a clock frequency generators in digital video and audio broadcast systems.

The 1526GLFT features a unique frequency locking mechanism, which provides glitchless switching and frequency accuracy of 12 ppm or better. The device relies on two basic components, a VCO (Voltage Controlled Oscillator) and a VDT (Voltage-to-Time Converter). The VCO is used to generate a voltage which is then converted to a time-domain signal using the VDT. The VCO is programmed using a digital word which is sent to a programmable control block. This digital word is used to select the output frequency by setting the voltage of the VCO.

The VDT then adjusts the output frequency of the VCO to the target frequency. This frequency is then compared against the reference frequency, and if the frequency difference is low enough, the device will start running. This frequency locking process enables the device to remain at a steady frequency, even when the external power supply and reference frequency vary. This makes the device ideal for applications where a stable frequency is required, such as in digital-to-analog and analog-to-digital converters.

The 1526GLFT is an excellent choice for those looking for a fast switching and low jitter clock generator for their high-frequency applications. Its wide range of features, such as its programmable output clock enable/disable option, a programmable output enable/disable, and a programmable output reference clock, make it a valuable addition to any system. Its frequency locking mechanism further ensures a glitch-free and reliable output, making it a great choice for those looking for a reliable and consistent frequency.
