PI49FCT20807QEX

PI49FCT20807QEX is an active delay line device based on FCT technology that provides good signal integrity and excellent signal conditioning.The device is an active delay line and acts as a buffer between a master clock and a master buffer. It provides up to 51ps of delay which guarantees accurate signal propagation from the master clock to the master buffer. It has a high skew output-to-input ratio of 0.34ps, making it ideal for synchronous applications.

Application Field

The PI49FCT20807QEX can be used in several different clock/timing applications. It’s especially useful for providing a buffer between master clock and master buffer. It can also be employed in distributed clock models, where it can provide the necessary delay to the system, allowing for clock synchronization. It can also be used in clock gating where it can provide a more accurate gating signal, resulting in more accurate system clock distribution.

Working Principle

The PI49FCT20807QEX ensures excellent signal conditioning of the clock signal by using phase-locked loop (PLL) technology. It operates via a dual-loop system where the input clock signal is first compared against a reference clock. If the two clocks have a phase/frequency discrepancy, the PLL circuit modifies the output clock frequency in order to match it with the reference clock. After the frequency has been adjusted, the PI49FCT20807QEX then delays the output clock by an adjustable amount, allowing for a more stable clock signal.

The PI49FCT20807QEX works in dual-phase mode, meaning it has two separate outputs that are in-phase and 180° out of phase with the input clock. This allows for better system clocking and synchronization, allowing for better signal integrity throughout the system. The PI49FCT20807QEX also has adjustable output drive strength, allowing it to be tailored for specific applications.

Overall, the PI49FCT20807QEX is an excellent device for providing a buffer between master clock and master buffer, as well as providing stable and adjustable clock distribution in distributed clock applications. With the adjustable output drive, it can be tailored to provide optimum performance in a variety of clocking conditions.
