SI5338Q-B04080-GMR Application Field and Working Principle

The SI5338Q-B04080-GMR is a clock and timing solution designed specifically for application-specific needs. It is a highly flexible, low-power signal generator optimized for providing multiple output clock signals from a wide range of frequently used input signals. This family of ICs is used in a wide range of applications, including clock signal generation for servers, switches, base stations, telecom equipment and other computing enabled devices.

Operational Overview:

The device contains six independently programmable PLLs with an integrated output buffer. The six hold two reference inputs, two reference outputs, two external clock inputs, and two external clock outputs. The two reference inputs are used to generate synchronous clock signals of the highest accuracy. The two reference outputs generate clocking signals of lower accuracy. The two external clock inputs can be used to generate additional synchronous outputs. The two external clock outputs provide more options for balancing the clock signal loading on a system.

Output Frequency Range:

The SI5338Q-B04080-GMR supports a frequency range of up to 160MHz for its six output clocks. The output channels are compatible with a wide range of synchronization frequencies from 38.9MHz to 160MHz. The output phase noise spectrum is typically -134dBc/Hz and the jitter is typically 0.15ps RMS.

Input Frequency Range:

The SI5338Q-B04080-GMR supports a range of input frequencies from 38.9MHz to 160MHz. The input frequency is divided down to the desired range of frequencies before being further subdivided by the chip’s frequency division networks. The chip is designed to accommodate a wide range of input frequencies and can even operate under low voltage or supply transients.

Digital and Analog Controls:

The SI5338Q-B04080-GMR can be configured via digital or analog control. The chip has an on-board serial bus interface, which can be used to program the chip. It also includes on-board digital potentiometer, which can be used to adjust the frequency and phase of each output channel. The digital programming can allow the user to select from one of several on-chip presets as well as enable a power management option.

Pros and Cons:

The SI5338Q-B04080-GMR has several advantages. Its high performance and flexibility make it suitable for a wide range of applications. The small size of the chip also contributes to its potential for system miniaturization. Its on-board frequency division networks can provide better control of clock signals. Additionally, the on-board serial bus and digital potentiometers can help reduce system complexity.

However, the SI5338Q-B04080-GMR has several drawbacks, requires an external reference clock, which may incur additional costs. Also, the maximum operating frequency of 160 MHz and the divider networks may not be suitable for certain applications. Additionally, the minimum operating voltage for the device is 5V and the maximum operating temperature is 105°C.

Conclusion:

The SI5338Q-B04080-GMR is a highly flexible, low-power signal generator optimized for providing multiple output clock signals from a wide range of frequently used input signals. It is suitable for applications such as clock signal generation for servers, switches, base stations, telecom equipment and other computing enabled devices. Its high performance, flexibility and low power consumption are major advantages. However, the need for an external reference clock and the limited frequency and temperature range are the main drawbacks of this IC.
