Crystals: 416F38422IDT Application Field and Working Principle

The 416F38422IDT is part of a family of High Speed CMOS Clock Generator and Clock Buffer devices belonging to the CRYSTALS product family. In the CRYSTALS family, clock generator devices are used to generate high-frequency clock signals and clock buffer devices are used to buffer and distribute those signals. The 416F38422IDT is a clock generator device that provides high-frequency, low-jitter clock signals for high-speed data and communication applications. In addition to being used in two-wire data and communication applications, the 416F38422IDT also finds application in multi-channel clock generators, frequency synthesisers, clock deskewing and clock synchronization applications.

The 416F38422IDT is a chemical-mechanical, sealed, surface mount device with a single output pin housed inside an 8-pin tape reel package. The 416F38422IDT includes a master oscillator which is programmed by the user to provide a wide range of frequencies. The frequency of the master oscillator is divided down to the output frequency by divide-by-N dividers, programmable by the user. Additionally, the 416F38422IDT includes a programmable output disable feature which can be used to control the output of the device.

The 416F38422IDT includes several features that enable it to be used in more demanding applications. These features include a wide operating range of 3.0V to 3.6V, an internal temperature compensation feature which allows the device to work at temperatures from -40°C to +125°C, and an interface protection feature that guards against ESD damage. Additionally, the 416F38422IDT includes a programmable power down feature, which allows the device to be powered down without resetting its internal registers.

The working principle of the 416F38422IDT is based on a type of phase-lock loop (PLL) that uses a voltage-controlled oscillator (VCO) to generate a high-frequency clock output. The device\'s VCO is programmed by the user to generate an output frequency that is divided down to the output frequency by divide-by-N dividers, which are also programmed by the user. The device includes an internal feedback loop which uses an on-die loop filter to maintain the phase and frequency relationship between the clock output and the reference clock source. Furthermore, the device includes a programmable output stretch feature, which allows the output signal to be stretched to accommodate the propagation delays of external components.

In summary, the 416F38422IDT is a high-speed CMOS clock generator device used in demanding applications such as two-wire data and communication applications, multi-channel clock generators, frequency synthesisers, clock deskewing and clock synchronization applications. The working principle of the device is based on a voltage-controlled oscillator (VCO) coupled with an internal feedback loop and a programmable output stretch feature. The device includes features such as an internal temperature compensation feature, a programmable power down feature, and interface protection features that guard against ESD damage.
