650R-01ILFT

The 650R-01ILFT is a high speed Ultra Low Power Clock Generator / CXC Oscillator from Alcontec (NXP). It combines the features of high linearity and low power consumption with a high level of flexibility, making it ideal for applications needing high throughput, low power, and cost savings. The main features are high frequency accuracy and stability, low power consumption, low noise, and low EMI.

The 650R-01ILFT combines an internal PLL, a crystal oscillator, and a configurable frequency synthesizer. The PLL provides a low jitter clock with low power consumption. The frequency synthesizer can generate multiple output frequency signals and is programmable, which allows users to customize the frequency and stability to their applications. The internal crystal oscillator, when backed up with an external crystal, ensures high accuracy and low EMI.

The 650R-01ILFT clock generator is designed to provide a wide range of output frequencies, ranging from 0.07MHz to 250MHz. It supports a local clock or can be synchronized to an external clock. It is also capable of providing output formats such as LVCMOS, LVDS, and DDR. The chip can be programmed through I2C, UART, and JTAG.

The 650R-01ILFT is an ideal clock solution for various applications such as networking, automotive, communications, video, audio, and medical devices. It is also suitatable for high speed interfaces like USB, PCIe, SATA and Ethernet. By utilizing the high frequency accuracy and stability of the 650R-01ILFT, design engineers can save time and money in system development.

In terms of its working principle, the 650R-01ILFT has an internal phase locked loop (PLL), which is used to generate the output clock frequency. The PLL locks onto a reference clock (which can be an external or an internal clock) and then generates the output frequency using a divider inside the chip. The output frequency is then tuned until it is in sync with the reference clock. This is done by controlling the phase and frequency discriminators, along with the charge pump current control and the loop filter. When the frequency is in sync, the PLL will stabilize and maintain a lock on the reference clock. In addition, the PLL can also be used to generate a higher frequency output by using a programmable frequency divider, or a VCO.

To sum up, the 650R-01ILFT is an excellent clock generator for high speed, low power applications. It has a wide range of output frequencies and is both cost effective and power efficient. Its features include low jitter, low noise, and low EMI, making it suitable for a wide range of applications. Additionally, the internal PLL and frequency synthesizer offer users the flexibility to customize their output frequency, giving them the means to tailor their system design to their specific requirements.
