SI5338B-B07751-GM: Application Field and Working Principle

The SI5338B-B07751-GM has become a popular device due to its ability to provide clock and timing solutions for many diverse applications that require both precision and reliability. This device is perfect for low-power, low-jitter, or applications requiring high accuracy, such as communications and FPGA/ASIC designs. This article provides an overview of the SI5338B-B07751-GM’s application field, working principle, and performance specifications.

Application Field and Working Principle

The SI5338B-B07751-GM is a clock generator, signal conditioner and timing device which can provide up to 16 frequencies on four independent outputs. This device is ideal for applications requiring high precision time and frequency synchronization, as it can generate and distribute accurately configured timing signals with very low jitter and low power. This device is typically used in communications, computing, and network-connectivity applications.

The SI5338B-B07751-GM is designed to operate from a single external reference input from a crystal oscillator, a PPL or even an external reference clock. With differential inputs and outputs, the SI5338B-B07751-GM offers increased robustness and lower jitter performance. Other features include input selection, programmable clock delay and skew, output enable and power down, as well as an audiophile-grade, low-noise power supplies.

The SI5338B-B07751-GM offers a great advantage over traditional timing solutions by combining configurable synchronized outputs with low jitter and low power capabilities. This device comes equipped with a local clock oscillator which provides the base signal and ensures that all the outputs are synchronized to the same signal. The local oscillator offers the highest performance in frequency multiplication and division, eliminating the need for multiple crystal oscillators which would have been needed if a conventional divider/multiplier circuit was employed. The SI5338B-B07751-GM is therefore a perfect solution for systems requiring multiple, low-noise, low-jitter, synchronized clock signals with low power requirements.

Performance Specification

One of the most attractive features of the SI5338B-B07751-GM is that it can generate and distribute accurate clock signals with extremely low jitter and low power. The device features a Jitter Attenuator mode which can be used to achieve even lower jitter performance on all outputs by eliminating jitter from the input clock source. With this mode enabled, the SI5338B-B07751-GM can generate synchronized signals with jitter as low as 0.12ps rms for both rise-and-fall edges, making it an ideal solution for transmission and storage applications.

In addition to its low jitter performance, the SI5338B-B07751-GM also offers excellent power efficiency. It can run at power levels as low as 12.5mW, making it well-suited for mobile applications. The device has a user-selectable power down mode which can reduce the power consumption by 3 - 4mW when the outputs are not in use. The SI5338B-B07751-GM also features a power-on reset feature which eliminates the need for external reset circuitry.

The SI5338B-B07751-GM is also very flexible in terms of its input and output configurations. It features configurable input and output formats, along with programmable clock delays and skews. It also has an integrated phase-lock loop (PLL) and voltage-controlled oscillator (VCO) which enables it to generate frequencies up to 1080MHz. The device has a wide range of voltage options, making it suitable for use in both 3.3V and 5V systems.

Conclusion

The SI5338B-B07751-GM clock and timing device is a versatile solution for applications requiring high performance, precise timing, and low power consumption. It is ideal for communications, computing, and network-connectivity applications and can generate accurate synchronized signals with very low jitter performance. It features programmable clock delays and skews, wide input and output options, integrated phase-lock loop (PLL) and voltage-controlled oscillator (VCO), as well as programs at power levels as low as 12.5mW. The SI5338B-B07751-GM is an ideal choice for applications requiring both precision and reliability.
