SI5338B-B01371-GMR

SI5338B-B01371-GMR is a high-performance, low-jitter clock generator that is versatile enough to solve almost any timing challenge in the Clock/Timing - Application Specific field. It is part of the SiTime’s Advanced Series of MEMS-based clock generators that offers application-specific features and performance in a low-jitter, low-power package with an ultra-small footprint. It is a highly integrated device that integrates clocks, PLLs, oscillators and signal conditioning circuitry while consuming only 10 mW of dynamic power.

Overview

The SiTime SI5338B-B01371-GMR clock generator provides a comprehensive set of application-specific solutions. It can generate up to 8 outputs with frequencies ranging from 8 kHz to 3.6 GHz and jitter as low as 250 fs RMS. The clock generator can generate pulse-plate clock signals, with adjustable delay and pulse width, as well as multi-level clocks with dedicated p- and n-level outputs. The clock generator can be configured to run in either spread-spectrum or frequency-locking modes, providing additional flexibility to users. It also supports “Dynamic Clock Synthesis”, which allows users to dynamically change their clock frequencies or parameters without having to re-program the chip.

Working Principle

The working principle of the SI5338B-B01371-GMR can be described in 4 main parts:

• The clock synthesizer generates a precise frequency from the input reference clock.
• The PLL and VCO circuitry multiplies the reference clock frequency to generate the desired output frequency.
• The phase-locked loop uses the phase difference between the generated and the reference clock to provide a feedback signal for the VCO.
• Finally, the clock generator modifies the final output in various ways, such as providing spread-spectrum, frequency-locking and dynamic clock synthesis functions.

The SI5338B-B01371-GMR is a powerful clock generator that provides the flexibility and performance to solve complex timing requirements. It is the ideal choice for applications requiring precise and stable clock signals in the Clock/Timing - Application Specific field.
