Working Principle

At the core of the 8T49N008A-006NLGI clock generator is a Voltage-Controlled Oscillator (VCO), which is used to provide the initial signal. This signal is then fed into the integrated Phase Locked Loop (PLL), which provides frequency multiplication and enables the device to generate frequencies that are higher than that of the input signal. The PLL is also used to reduce jitter and ensure long-term stability.The 8T49N008A-006NLGI also includes an on-chip temperature-compensated quartz crystal oscillator (TCXO) for further jitter reduction. The frequency of the output signal from the 8T49N008A-006NLGI can be precisely adjusted using an integrated two-wire serial port interface (SPI). The SPI can also be used toprogram the phase and frequency tolerances for enhanced accuracy.
