SI5338C-B02268-GMR

Introduction

The SI5338C-B02268-GMR (SI5338C) is a fully-integrated, low-power, multi-output timing solution designed to meet the needs of the application specific timing markets.

Application Field

The SI5338C is designed to provide a low-power clock solution for a wide variety of different applications. It features an extensive range of output frequencies, with a maximum output frequency of 250MHz. It is able to support multiple output buses, such as GPIO and I2C, for clock distribution across a variety of devices. Applications include point-to-point communications, network, automotive, industrial, medical and consumer electronics.

Working Principle

The SI5338C uses an internal digital core clock to generate a low-frequency clock. This clock is then used as the source for the various output clocks. The output clocks can be divided into two or more output frequencies, with the option of a single or dual output frequency. Alternatively, the device can be configured to operate in a cascading mode, with multiple output frequency generations available. The output frequency is determined by the appropriate combination of input and clock settings, which can be programmed via the on-board registers.

The SI5338C incorporates a Programmable Spread Spectrum (PSS) feature to reduce EMI in the output clocks. The PSS feature can be enabled to reduce the peak-to-average power ratio of the output clocks, while still meeting the spectral requirements of an application.

The SI5338C includes an integrated Voltage Controlled Oscillator (VCO). This VCO can be used to tune the input clock for optimal performance in different operating conditions. The VCO can also be used to reduce operating power. The device is also capable of operating in a lower-power state, with reduced output frequencies.

Conclusion

The SI5338C is a highly integrated, low-power multi-output timing solution that is capable of generating a wide range of frequencies. It supports a variety of output buses and features an integrated PSS and VCO, allowing for optimal performance and reduced operating power. The SI5338C is ideal for a wide range of applications, including point-to-point communications, industrial, automotive, and medical.
