PI6C2408-1LE devices are Clock/Timing – Clock Generators, PLLs (Phase Locked Loops), Frequency Synthesizers. The device includes integrated logic, control, and buffer blocks for generating a high resolution digital clock for various timing applications. The PI6C2408-1LE includes an internal crystal oscillator that sets the output frequency accuracy, and can be programmed into various frequency ranges.

PI6C2408-1LE devices offer easy-to-use integrated frequency control, output timer, and power management devices, as well as an on-chip RTC (Real Time Clock). It supports up to 64MHz input, divided output (up to 256 divisions) of frequency and can be programmed to nearly any frequency range, delivering accurate frequency resolution and stability. The device is designed to offer on-board power-down, power fail, and monitoring features.

PI6C2408-1LE’s application field covers several areas that require high accuracy clock timing, such as communication infrastructures, medical imaging, multimedia and RF Modules. PI6C2408-1LE’s power management system includes a power sequencing memory control that automatically performs an orderly shut down of the system when power fails, and allows for time slicing of power supplied to various circuits in order to reduce power consumption.

Regarding its working principle, PI6C2408-1LE utilizes phase-locked-loop (PLL) technology to generate a signal at a frequency that is an integer number of times greater than the reference clock signal. The PLL system includes a low-bias current, variable duty cycle programmable VCO (Voltage Control Oscillator), and a variable-gain phase detector. An oscillator is used to compare the reference signal to the cyclically varying output frequency of the VCO, and synchronizes the two until they are phase-locked at the same frequency.

PI6C2408-1LE also has a temperature compensation circuitry that adjusts the output frequency as the system temperature changes. This improves the accuracy of the generated clock over the entire operating temperature range. The device also includes power-down circuitry, which allows the device to safely enter a low-power state if a power loss occurs. By cycling the clock, the device can power down the system when not in use to reduce the overall system power consumption.

In summary, PI6C2408-1LE’s Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers can provide excellent timing accuracy and stability in applications such as communication infrastructures, medical imaging, multimedia, and RF Modules. It utilizes PLL technology to lock a reference input signal and an on-board oscillator to generate a frequency which is an integer number of times greater than the reference signal. Run-time frequency adjustment, temperature compensation, and power-down features are also included to provide greater accuracy, efficiency, and longevity in dynamic systems.
