The SI5335D-B04721-GM is a clock/timing generator, or frequency synthesizer, that combines a programmable, low-noise clock generator and a wide-frequency-range PLL (Phase Locked Loop) synthesizer integrated in a single chip. It provides a reliable and versatile device used to produce the desired clock signals and frequencies. It generally produces much higher frequencies than previously available due to its ability to carry out complex digital designs that are built around it.

The SI5335D-B04721-GM is part of the 5335 family of PLL clock generators. It is used for a variety of applications including automotive Infotainment, Wi-Fi, Ethernet, Industrial Control, Avionics, Telecommunications, High-Speed Digitial Interfaces, Compliance Testing and Advanced Radio Communications. It is suitable for applications that require high performance with wide operating temperature range and low power consumption. It can be made to specifically meet customer needs with custom cutting layouts and frequencies.

The 5335 family of PLL clock generators includes a wide frequency range, with output frequencies ranging from 10 MHz to 10 GHz. It consists of several components, including a phase-locked loop frequency synthesizer, a low noise clock generator, a smart reset processor and a low skew output buffer. The PLL frequency synthesizer – is used to generate high-precision, low jitter and wide-frequency range clock outputs. The low-noise clock generator features a digital oscillator and a divider which together enable the generation of multiple frequencies with low phase noise and a fast switching time to different output frequencies. The smart reset processor provides additional control of internal signals and hardware reset functions. The output buffer is responsible for generating low jitter and low skew clock distribution.

The SI5335D-B04721-GM provides various programmable input/output ports and multiple independent reference clocks. An external analogue reference clock input allows an interface with standard crystal oscillators. This allows for a wide range of reference clock frequency settings which can be used to generate different output frequencies. It also provides precise controls like the setting of the phase noise filter bandwidth, the output buffer levels and slew rate control settings.

Additionally, the SI5335D-B04721-GM includes various integrated functionalities. These include a Zero Delay Buffer to eliminate additional delays between reference clock and PLL output, an analog lock detect (ALD) to monitor the phase locked loop, and an SSM (Soft Start Mode) to optimize the system power-up sequence. It also features SPI, I2C and JTAG digital programming interfaces.

In summary, the SI5335D-B04721-GM is a highly versatile frequency synthesizer that is widely used in a variety of applications that require high precision and low-noise clock generation. Its wide range of features and programmable inputs/outputs make it a great choice for low power and high performance applications.
