The SI5345A-C-GMR is a high-precision jitter attenuator and programmable clock generator from Silicon Laboratories. It offers a range of features and benefits specifically designed for clock/timing applications.

The device is a CMOS generation frequency synthesizer with a low-input power, small form factor and a wide supply voltage range of 3V to 3.6V. It can automatically detect its operating conditions and offers the user a choice of multiple operating modes.

The SI5345A-C-GMR features a low power clock synthesis integral nonlinearity (INL) compensator, five differential or single-ended user-selectable output buffer types and Glitch-Free input (GFI) capability. It has an integrated jitter attenuator that can suppress input jitter with a jitter improvement of as much as 1.5x over natural line loading. Internal settings can adjust the amount of jitter, as well as limit the total amount of spurious emissions.

The SI5345A-C-GMR has the ability to perform a variety of features, including output clock frequency tuning, spread spectrum mode selection, output-to-input jitter attenuation, and output signal amplitude control. It supports a variety of applications and is ideal for clock signal conditioning. Some of the common application areas include telecommunications, data/storage, test and measurement, military and medical.

The SI5345A-C-GMR works on the principle of frequency multiplexing. This is a technique in which the device divides the input signal into multiple frequency components, and then combines them in various ways to produce the desired output signal. This process eliminates unwanted noise from the signal, thus improving signal integrity and accuracy. The device works by modulating the input signal frequency with a certain amount of jitter, in order to pass it through a phase-locked loop (PLL). The PLL ensures synchronized modulation and frequency control of the resultant signal.

The SI5345A-C-GMR is a versatile device that can be used in a variety of applications requiring precision timing and synchronization. It offers users a broad array of features and benefits, such as low jitter performance, integrated jitter attenuation, low input power and small form factor, multiple frequency modes, spread spectrum mode selection, and more. The device offers a cost-effective solution for clock/timing applications, and is suitable for a wide variety of markets.
