The PL138-28OC-R is a differential/pseudo-differential input to single-ended output, low jitter clock buffer, which is a popular part of the clock/timing family. This particular device allows the user to adjust the output skew and slave devices to provide a wide range of digital performance enhancement. The device is suitable for a variety of applications, including clock pre-emphasis, clock recovery, clock and data reset, data synchronization and jitter elimination.

The PL138-28OC-R has an on-chip VCO (Voltage Controlled Oscillator) designed to vary its voltage output by a specified level in response to an output clock input. This adjustable voltage is sent to the output via a digital buffer, with adjustable output skew and loopback compensation circuitry.The VCO produces an output frequency that is the same as that of the clock input, but with the added capability to adjust the output skew and the output amplitude.

The PL138-28OC-R allows users to adjust the skew and slave devices to achieve desired levels of jitter suppression, data transfer performance, and clock synchronization. The output amplitude can be synchronized to the clock input to provide higher noise immunity. The device also employs automatic power management, allowing it to go into a low-power state when it is not in use.

The PL138-28OC-R is ideal for meeting requirements of high-performance clocking and timing designs. Its versatility and ability to adjust skew and slave devices make it an ideal solution in general-purpose clock/timing designs. Additionally, the low-jitter operation and high-noise immunity make it suitable for a wide range of applications, such as in data recovery and clock-and-data reset circuits.

In addition to the adjustable skew and slave device input capability, the PL138-28OC-R offers clock recovery and data reset functionality. The clock output can be synchronized to the clock input in order to reduce jitter and improve data transfer performance. Additionally, the device can be used to provide a reset signal for external logic, allowing the user to safely reset their systems.

Finally, the PL138-28OC-R offers adjustable termination between the analog and digital outputs, allowing the user to fine-tune their designs and achieve the best-possible performance. This adjustable termination helps reduce noise, improve data transfer performance, and increase system reliability.

The PL138-28OC-R is a powerful clock buffer, offering adjustable skew and slave devices to simplify user designs and meet a wide range of clocking and timing requirements. Its adjustable termination, low jitter, and high noise immunity make it an ideal part for a variety of applications.
