Working Principle

The 23S08-1DCGI8 uses a Frequency Synthesis (FS) based architecture to generate low-jitter high-frequency clock signals from a low-cost oscillator, resulting in cost and efficiency advantages.

The Frequency Synthesis (FS) architecture employs a combination of Phase Locked Loop (PLL) and Digital Clock Manager (DCM) technologies to achieve precise domain synchronization and precise fine-tuning of the output frequency. The PLL synthesizes the desired output frequency by locking onto and controlling the oscillator frequency. The DCM then takes the output of the PLL and digitally optimizes the frequency and duty cycle of the output clock.

In addition, the 23S08-1DCGI8 is designed to be resistant to noise interference. Noise rejection techniques such as Frequency Division Noise Reduction (FDR), Transistor Overlap Isolation DoubleTris (TOID), Pre-Distortion Technology (PDT) and Electrostatic Discharge (ESD) protection ensure that the device has excellent noise and immunity characteristics.

In summary, the 23S08-1DCGI8 is a high-performance single-chip clock generator providing superior jitter and noise performance in an integrated package. It can be used to generate high-frequency low-jitter clock signals in a variety of consumer and industrial applications. The device\'s use of Frequency Synthesis (FS) architecture combined with noise rejection techniques make it an ideal choice for designers looking to reduce cost and increase efficiency in their clock designs.
