The SI5338A-B08297-GMR is an application specific clock timing solution, intended for a variety of applications related to telecommunications, computing, automotive and industrial sectors.

The device combines various programmable elements such as clock generators and dividers, PLLs and timing delay blocks, to provide an integrated clock tree solution built around crystal oscillators with improved accuracy and stability.

The clock/timing device provides an ideal solution for applications that require low-power, low-jitter and low-noise timing solutions.

The main features of the device include a wide frequency range (from 16 kHz to 1.7 GHz), a wide range of input clocks (from 1.5 to 4.5 V ), and support for up to 24 differential clock outputs.

The SI5338A-B08297-GMR also supports a variety of clock types, including LVCMOS, LVDS and SSC.

Working Principle

At the heart of any clock/timing device is a phase-locked loop (PLL). A PLL is a closed-loop circuit that consists of a controlled oscillator and a voltage controlled oscillator (VCO). The PLL works by comparing the frequencies of an input signal, which is referred to as the reference clock, to an adjustable frequency generated by the VCO. If there is an error between the two frequencies, the PLL adjusts the frequency of the VCO to match the reference.

In the SI5338A-B08297-GMR, the PLL is used to generate multiple frequencies from a single reference clock, which can then be further divided by dividers to generate lower frequency signals. Multiple PLLs can also be used to generate different frequency output signals from a single reference clock.

Application Field

The SI5338A-B08297-GMR is ideal for applications that require low-power, low-jitter and low-noise timing solutions. Due to its wide frequency range and ability to generate multiple frequencies from a single reference clock, the device is suitable for a range of applications, including:

• Telecommunications (e.g., radio base stations, radio control systems, base station controllers and protocol converters)
• Computing (e.g., data storage systems, networking, networking switches and routers)
• Automotive (e.g., control systems, powertrain systems and safety systems)
• Industrial (e.g., motor controllers, remote control systems and automation systems)

The SI5338A-B08297-GMR is also suitable for a wide range of timing solutions such as clock synchronization, clock distribution and clock generation. It is ideal for applications that require low-jitter clock signals, as well as applications where accurate and robust timing solutions are required.

In addition, the SI5338A-B08297-GMR can be used to synchronize multiple systems with a single timing source, or multiple timing sources with different frequencies. This is achieved by the use of PLLs and dividers, which can be used to generate multiple frequencies from a single reference clock. This type of clock synchronization provides improved jitter performance and is ideal for applications that require highly accurate timing solutions.
