Introduction

The SI5346A-D06344-GMR is a clock generator and Phase-Locked Loop (PLL) IC designed for broadband network applications. It is optimized for use in cable, home networking, and server applications. The SI5346A-D06344-GMR is part of the SiTime family of clock generation and PLL devices, which provides extremely low jitter and superior performance in an integrated package.

Application Field

The SI5346A-D06344-GMR is ideal for applications that require low-jitter, low-power clock distribution or synchronization. It can be used in various applications, including:

• Cable set top boxes
• Home networking infrastructure
• Servers
• Digital video broadcasting
• Communication systems
• Network-attached storage systems
• Base stations and remote receivers
• Military and aerospace systems

In particular, the SI5346A-D06344-GMR is well-suited for applications requiring frequencies from 8 kHz to 600 MHz.

Working Principle

The SI5346A-D06344-GMR is a single-chip PLL device that can generate up to eight clock outputs with frequencies ranging from 8 kHz to 600 MHz. The device can generate up to five identical outputs, or up to five non-identical outputs, or a combination of both by using the four programmable PLLs. The SI5346A-D06344-GMR requires a single external source clock, which is phase-locked to generate the desired clock outputs. The device can be programmed via I2C or SPI bus.The device uses an internal programmable digital phase-locked loop (PLL) to generate precise and jitter-free clock outputs. It features a low-power consumption of only 1.1 mW/MHz, making it ideal for applications in portable or battery-operated systems. The SI5346A-D06344-GMR also features an integrated oscillator that eliminates the need for an external crystal or clock source. This eliminates the possibility of clock source inaccuracy or drift. The device includes various advanced power management features that enable the device to enter a low-power mode when inactive. The device also has a hot-plug feature that allows it to be disabled or enabled on the fly, minimizing system downtime and reducing power consumption.

Conclusion

The SI5346A-D06344-GMR is an ideal clock generator and PLL designed for broadband network applications. It features an integrated oscillator and an integrated programmable digital PLL, allowing it to generate precise, low-jitter clock outputs from 8 kHz to 600 MHz. The device also features an optimized power management system and hot-plug feature, making it ideal for applications in portable or battery-operated systems.
