The SI5341A-D-GMR is a clock generator, phase-locked loop (PLL), and frequency synthesizer from Silicon Labs. The device supplies multiple low-jitter clock signals to system timing circuits, including microprocessors and FPGAs. It is designed for applications that require multiple clock frequencies with tight tolerances and a low jitter and phase noise footprint.

Features

• Programmable PLL with both conventional and Spread-Spectrum modes
• Output frequencies of up to 1200 MHz
• Frequency synthesis up to 8 outputs
• Zero delay spread (ZDS) buffer
• Extended phase/frequency control
• Frequency synchronization/tracking
• Spread-Spectrum frequency dithering

Applications

The SI5341A-D-GMR is especially suited for applications where clock distribution and synchronization are crucial, such as radios, personal computers and peripheral components, distributed audio and video systems, telecom, and other high-speed digital systems. It is also used in a wide range of industrial, instrumentation, and automotive applications.

Working Principle

The SI5341A-D-GMR is a clock generator, PLL, oscillator, and frequency synthesizer in one package. It can be used to generate a wide range of output frequencies up to 1.2 GHz. The device features programmable multi-modulus dividers that can be used to create multiple clock outputs of different frequencies. The frequency of each output can be programmed using the device registers.

The SI5341A-D-GMR uses a conventional PLL design. A reference clock of either a crystal or an external reference signal is fed into the device. The device then uses the reference signal to generate multiple clock signals of different frequencies that are selected and controlled using the programmable multi-modulus dividers. The frequency of each output can be programmed using the device registers.

Once programmed, the SI5341A-D-GMR can be used to generate clock signals of precise frequency with low jitter and low phase noise. It also has an extended phase/frequency control feature which can be used to adjust the output frequency of each clock signal. The device also supports synchronization and tracking of multiple clock signals.

The SI5341A-D-GMR also supports Spread-Spectrum frequency dithering which can be used to reduce noise in mixed-signal systems. The Spread-Spectrum dithering feature reduces peak-power and improves signal-to-noise ratio in sensitive analog circuits.

Conclusion

The SI5341A-D-GMR is a high-performance clock generator, PLL, and frequency synthesizer for applications that require multiple clock frequencies with tight tolerances and low jitter and phase noise. It is designed for use in high-performance clocks for radio, telecommunication, distributed audio and video systems, personal computers, and other digital systems. Its extended phase/frequency control, frequency synchronization/tracking, and Spread-Spectrum frequency dithering features make it an ideal choice for applications where precise clock signals are critical.
