The SY100S811ZH is a high speed clock repeater/buffer device designed for use in a variety of applications. It has a 3.2V to 3.6V supply voltage range and a low-voltage differential signal (LVDs) input that operates from 2.5V to 3.3V and can accept clock frequencies of up to 800 MHz. It is capable of delivering eight selectable clock output frequencies with low noise and excellent jitter performance. The SY100S811ZH incorporates both a System-on-Chip (SoC) and a synchronous, simple, phase-locked loop (PLL) clock generation architecture. It is suitable for a wide range of low-noise, high-bandwidth applications in the consumer, industrial, and automotive space.

The SY100S811ZH clock repeater/buffer operates on two inputs: an LVTTL input, and a master clock input. The LVTTL input, also known as a reference clock, is used as the clock source for the initial synchronization. The master clock input is used to reset the internal clock generator, establish the oscillator frequency, and set the internal PLL loop frequency. The master clock input can accept frequencies from 0.5 MHz to 800 MHz. The output clock is generated by the PLL and is mirrored to each of the eight outputs.

The SY100S811ZH clock repeater/buffer offers excellent clock performance that exceeds the requirements of low-noise, high-bandwidth applications. The jitter performance is excellent, with a 9ps tp-jitter rating. The device is also very stable, with a cycle-to-cycle jitter of 5ps that is maintained over a wide temperature range. It is also immune to deterministic jitter and has no phase or frequency shift between multiple stcorresponding outputs. As a result, all eight outputs maintain identical frequencies with minimal jitter.

The SY100S811ZH clock repeater/buffer also features an easy, yet comprehensive, programming interface that can be accomplished using the supplied software. The user can configure the device in several ways, namely setting the final frequency, the oscillator frequency, the phase delay, and the VCO current settings. The device also features a power-down and reset pin, allowing for a smooth transition when switching between working and standby modes.

The SY100S811ZH’s small form factor, low power consumption and high speed capabilities make it an ideal choice for applications such as automotive infotainment, cellular base stations, digital TV and set-top boxes, digital audio systems, and wireless communications. In these applications, the device can be used to extend the clock range by introducing low-noise, high-bandwidth clock signals across multiple clock domains. In addition, the device can function as a general repeater/buffer, supporting the distribution of multiple low-noise clock outputs from a single source.

The SY100S811ZH is a versatile and reliable clock repeater/buffer that can be used in a variety of applications. Its small form factor and power consumption make it a perfect fit for low-noise, high-bandwidth applications. The device is also easy to configure and provides excellent jitter performance for its intended applications.
