Clock Buffers, Drivers, and Repeaters are typically used to enhance system performance and reliability by buffering, driving, or repeating clock signals within a system. The PCKEP14D is a high-performance clock buffer, driver, and repeater designed to provide very low skew, low jitter and low EMI/RFI noise. This article will discuss the application fields of the PCKEP14D along with its working principle.

Application Field

The PCKEP14D is best used in applications where the generation of very low skew, low jitter and low EMI/RFI noise is critical. The PCKEP14D is especially suited for applications such as:

• Industrial automation systems
• Automotive/driver assistance systems
• Medical imaging systems
• High speed communications
• Time-critical systems
• Switched-mode power supply systems

It can also be used to buffer high-speed signals in LAN and WAN systems, as well as to provide clock synchronisation in digital systems.

Working Principle

The PCKEP14D has two integrated digital logic blocks that enable the clock signal to be buffered, driven, and repeated. The first block is the buffer, which amplifies the clock signal to a specific level. The second block is the driver, which buffers and drives the clock signal. Finally, the third block is the repeater, which receives the clock signal and repeats it to the necessary outputs.

The PCKEP14D utilises advanced current-mode logic (CML) techniques to drive and repeat the clock signal. This allows the PCKEP14D to provide very low skew, low jitter and low EMI/RFI noise. The CML technology also allows the PCKEP14D to operate at very high speeds, up to 2.5Gbps.

To ensure that the clock signal is repeated accurately, the PCKEP14D utilises slew rate control. This allows the PCKEP14D to ensure that the transition edges of the clock signal are as smooth as possible, resulting in better signal accuracy.

The PCKEP14D is also capable of providing 8-bit-wide differential clock signals, which can be used for applications such as jitter and phase noise testing. This allows the PCKEP14D to provide a wide range of clock signal performance, from low-jitter operations to high-jitter operations.

Conclusion

The PCKEP14D is a high-performance clock buffer, driver, and repeater designed to provide very low skew, low jitter and low EMI/RFI noise. It is best used in applications where low skew, low jitter and low EMI/RFI noise are critical, and is especially suited for automotive, medical imaging, and high speed communication systems. The PCKEP14D utilises advanced current-mode logic techniques to drive and repeat the clock signal, allowing it to operate at very high speeds and to provide 8-bit-wide differential clock signals. This makes the PCKEP14D an ideal choice for applications requiring high-performance clock signal routing.
