Produced by Fairchild Semiconductor, the PI49FCT38072CQE is a high-speed buffering and relaying device designed for use in telecommunications, networking and data storage applications. It is a member of the FCT family of devices, providing high performance and low cost in a dense 7-pin package.

The PI49FCT38072CQE is a clock buffer and data relay device that is commonly used in telecom, networking and data storage systems. It provides the needed functions for clock synchronization, buffering, and data exchange in the presence of large amounts of noise. The device is designed to minimize skew between two different clock sources, and also provides low-frequency CLKOUT buffers to reduce the transmission line effects associated with long ran signals.

In terms of its physical dimensions, the PI49FCT38072CQE is a 7-pin package measuring 0.76 mm x 0.76 mm. Although relatively small, the device offers eight multi-data paths for buffering and 11 low-frequency buffers for clock synchronization. It also features a controlled slew rate of 0.7V/ns and a maximum operating frequency of 100MHz.

The working principle of the PI49FCT38072CQE involves the use of clock and data buffers to provide low-skew and reliable transmission of CLKOUT signals. The device provides two CLKOUT buffers that are driven by a dedicated input clock source. These two buffers serve to reduce the transmission line effects associated with long-range signals, ensuring that there is minimal disturbance on the clock signal. In addition, the two buffers serve to reduce or eliminate the effects of noise on the clock signal as well as to provide a longer transmission path for the signal.

The PI49FCT38072CQE also features an on-chip spread spectrum oscillator circuit. This spread spectrum oscillator circuit helps to reduce the number of spikes due to crosstalk and noise. Furthermore, the device’s small form factor and low-cost make it an ideal choice for a variety of clock and data buffering applications.

In conclusion, the PI49FCT38072CQE is a high-speed buffering and relaying device that provides both clock and data buffering for low-skew and reliable transmission of both clock and data signals. It features a maximum operating frequency of 100MHz and a small form factor that makes it suitable for a variety of applications in the telecommunications and data storage industries. Its two CLKOUT buffers serve to reduce the transmission line effects associated with long-range signals, while its on-chip spread spectrum oscillator helps to reduce the number of noise spikes due to crosstalk. Lastly, its low cost and remarkable performance make it a great choice for a variety of clock and data buffering applications.
