SI4133T-GM is a clock generator, phase locked loop (PLL) and frequency synthesizer in one integrated circuit (IC). The device offers high performance, low jitter and minimal phase noise, making it suitable for the transmission of high-speed serial data in a wide range of application fields.

A clock generator produces an internal clock signal which is used to time events in digital circuits. The clock signal is generated from an external clock source, such as a quartz crystal oscillator, or from a PLL. A PLL is a circuit which is used to adjust the frequency of the internal clock signal to match a desired frequency, without losing its phase relationship with the external clock. A frequency synthesizer is a circuit which is used to generate multiple clock frequencies from a single external clock source. The SI4133T-GM combines all these functions into a single IC.

The SI4133T-GM is a high-speed clock generator that can generate up to four separate output clocks from a single external reference clock. The device accepts a 37.5MHz to 500MHz reference clock frequency and produces up to four separate output clock signals, with independent frequency and phase settings. The clock output frequencies can range from 1MHz to 156MHz. The output clock signals can also be jittered or routed through an internal PLL to reduce the jitter. The outputs also feature drives up to 1000mA.

The SI4133T-GM also features a low-power spread spectrum mode, which reduces the peak-to-average power ratio when multiple output clocks are in operation. This allows the user to reduce EMI radiation in the environment, while still maintaining high clock distribution accuracy.

The SI4133T-GM is well suited to many application fields, such as communications, data processing, and computing. In these fields, the device can be used to generate accurate and reliable clock signals, at multiple frequencies, for use in high-speed serial interfaces. The device can also be used for video processing, where it can generate multiple video clocks, with jitter-reduced outputs for improved image quality. The device can also be used for power control applications, where it can generate multiple Pulse Width Modulated (PWM) signals, with tight jitter tolerances, for improved power control accuracy.

The SI4133T-GM includes many features which increase its versatility, such as a low power shutdown mode, input and output dithering, and spread spectrum mode. These features make the device suitable for a wide range of applications. The device also requires minimal external components, which reduces the design time and cost.

In summary, the SI4133T-GM is a high-performance, low-jitter, minimal phase noise clock generator, phase locked loop and frequency synthesizer in one integrated circuit (IC). The device offers a wide range of frequency and phase analysis and distribution capabilities, which make it suitable for a variety of applications. The device also requires minimal external components, which reduces the design time and cost. The SI4133T-GM is a perfect choice for many applications, such as communications, data processing, and video processing.
