PCK351DB,118

Clock buffers, drivers and PCK351DB,118 are essential in clock/timing applications. There are multiple clock buffer architectures, each having certain unique characteristics that depend on their application field and working principle.

Clock buffers are high speed, low-power, serial data distribution buffers that generate multiple copies of the same clock signal. They are also referred to as level converters, fan-in and fan-out buffers, or distribution buffers. These buffers offer highly reliable distribution of input clock and data signals with minimal skew and jitter. As such, they are often used in applications where minimal skew and jitter are required, such as high-speed busses and SerDes interfaces. The most common type of clock buffer is the Non-Inverting Buffer which takes one clock signal as an input and produces multiple copies of the same signal with no inversion or phase change. These buffers are often used to drive synchronous logic when the speed of the logic is dependent on the speed of the reference clock signal.

Clock drivers are used to transmit clock signals within a system. Clock drivers are often used when there are large distance between the source and destination of the clock signal. Clock drivers use signal regeneration or signal conditioners to increase the strength of the signal. This helps, as signal losses increase with distance, and this allows for longer transmission distances. Clock drivers may also be used to convert a small-amplitude logic signal into a higher-amplitude signal and vice versa. This allows for the signal to reach long distances while still maintaining adequate noise margin and power savings.

PCK351DB,118 is a type of Clock Buffer, or Level Converter, usually used in microprocessor and low jitter, high speed clock signal applications. It is an Inverting Buffer, which takes one clock signal and generates two complementary outputs; rising and falling edges. It is perfect for applications such as clocking in digital designs and driving high speed logic, where it is important to have low jitter. The outputs of the PCK351DB,118 are also fairly low in this regard. PCK351DB,118 also includes temperature and supply voltage tracking to ensure accurate clock synchronization of the outputs.

In conclusion, clock buffers, drivers and PCK351DB,118 are important components in the clock/timing field. Clock buffers are used to generate multiple copies of the same clock signal, while clock drivers are used to condition and strengthen signals to allow long transmission distances. PCK351DB,118 is a type of inverting buffer, used to generate two complementary clock signals as lower jitter outputs. All of these components have their own application field and working principle that make them essential in clock/timing applications.
