SY100H842LZI are known for their strong performance in high speed clock and data inputs/outputs that require limited noise, low skew and good symmetry. This kind of device has been widely used in many different applications and is considered as one of the best clock buffers around.

Working Principle of SY100H842LZI

The SY100H842LZI is a low noise, low skew, 4:2 differential clock buffer. This kind of device has several input signals (IN[0:3]) and two output signals (OUT0 and OUT1). It is designed to be used as a clock distribution device, or as a level translator between two logic families, by buffer or driving the input clocks into the output clock signals. The device is based on non-overlapping clock technology and offers excellent latency, low noise and low skew performance.

The SY100H842LZI consists of four buffers and two differential output buffers. Each of the four buffers accepts one of the four inputs (IN[0:3]), and amplifies the input clock signal into a differential, balanced signal that is transmitted to the differential output buffer at the output of the device. The output buffer then converts the differential signal into a single-ended signal that is presented on one of the two outputs (OUT0 or OUT1).

The SY100H842LZI has a built-in skew mechanism, which helps in reducing the total loop delay of the signal path. This unit is internally clocked to react to input buses, and can be programmed to be clocked to react within a certain range. The device is also equipped with adjustable load impedance, which helps in reducing the total number of devices, as well as reducing the power consumption of the device, which makes it suitable for applications that require low power operation.

In addition, this device also features fail-safe design for power down conditions, meaning that the outputs of the outputs of the device are set to the low logic state, thus eliminating the possibility of undesired output signal behavior. The device also supports hot insertion and removal, making it more reliable in environmental conditions.

Conclusion

SY100H842LZI is a great device when it comes to drive clock and data signals in high speed applications that require low noise and low skew performance. This device is equipped with a number of features that make it suitable for a variety of applications, ranging from computer systems to industrial data transmission. Its timing characteristics make it suitable for intermodulation elimination designs, high-frequency clock distribution circuits, clock multiplication designs and multi-drop bus structures.
