The PL135-480 clock buffer is a high-performance six-output differential clock buffer that is designed to provide clock signal buffering, distribution, and isolation. It can be used to extend the length of a single channel clock line while amplifying, isolating, and distributing the signal to multiple devices. This clock buffer features an industrial grade package with an operating temperature range from -40°C to 125°C, making it an ideal choice for reliable operation in harsh environments. This buffer is ideal for applications that require multiple clock outputs with relatively low-skew performance, such as FPGA clock distribution.

Features of the PL135-480 Clock Buffer

The PL135-480 features several advantageous features that make it ideal for a variety of applications. It features an industrial temperature range from -40°C to 125°C. It is a six-output differential clock buffer, with a single input and six differential outputs. All of the outputs are functionally identical, meaning that they are all buffered, isolated, and amplified versions of the main clock signal. This means that each output is synchronized to the main input clock frequency and phase, with very low skew values (< 1ns) between the outputs.

The PL135-480 clock buffer also features an adjustable output current drive of up to 16mA, allowing it to drive longer clock lines and larger trace capacitance than other similar clock buffering devices. This makes it ideal for applications with long board-to-board runs, or with large amounts of trace capacitance. The output voltage of the clock buffer is 2.5V, allowing it to interface with most FPGA clock circuitry.

Applications of the PL135-480 Clock Buffer

The PL135-480 is ideal for a variety of applications that require multiple low-skew clock outputs over long distances with relatively low power consumption. It can be used to drive clock signals over long board-to-board runs, or to fan out clocks to multiple devices. It can also be used as a clock buffer in FPGA clock distribution circuits, as it is capable of driving clock outputs with very low skew values.

The PL135-480 clock buffer is also ideal for applications that require high reliability in harsh environments, such as automotive and industrial applications, due to its industrial temperature range and adjustable current drive. This buffer can also be used in a variety of other applications that require precision synchronization and low skew, such as high-speed networking and data acquisition.

Working Principle of the PL135-480 Clock Buffer

The PL135-480 clock buffer is designed to provide buffering, isolation, and amplification of clock signals. The basic principle is simple – an input clock signal is amplified and converted to a higher voltage and current to drive multiple outputs. This allows for multiple devices to be driven from a single clock source with very low skew values between the outputs.

At the core of the PL135-480 clock buffer is a Type I PLL circuit. This circuit provides the buffering, isolation, and amplification of the input clock signal. This PLL circuit is designed to track the input clock frequency and phase and to provide low-skew outputs. The adjustable current driver also allows the device to drive longer traces and higher capacitances than other similar devices.

The PL135-480 clock buffer is a high-performance differential clock buffer designed to provide precision synchronization and low-skew output signals to multiple devices. It can be used in a variety of applications that require multiple clock outputs with low-skew synchronization and is ideal for FPGA clock distribution.
