PI49FCT32806HE, belonging to the family of Clock Buffers, Drivers, is a non-inverting 3.3V LVCMOS/LVTTL Clock Buffer. This is specifically designed to be used with Clock focusing and Clock Centering which result in better performance. It can robustly operate over the temperature range of -40°C to +85°C. The output is enabled when an 11.5~21.5MHz reference clock is applied to input pin.The core of the PE49FCT32806HE is a logic chip, powered by a 3.3V power source. It utilizes differential logic and can handle input at 11.5~21.5MHz range with 400ps rise and fall time. The clock signals presented to pin 7 and pin 8 are differentiated and used to produce a non-inverted output of the reference clock on the output pin 9. The output duty cycle is slightly skewed by the differential logic block, resulting in a faster high pulse and a slightly slower low pulse which optimizes the duty cycle of the output signal.The PE49FCT32806HE is suitable for use in many applications ranging from high speed clocks in data capture devices, such as digital cameras and analog-to-digital converters, as well as real-time communication systems such as Ethernet and USB. It is also popular for high speed serial protocol communications, especially for devices that require jitter-free clock generation. This device is particularly useful for applications in which a reference clock needs to be clocked from multiple sources with minimal clock skew, as the device features a built-in matched delay line, allowing for equalized clocking for a main and a remote reference clock.The PE49FCT32806HE is equipped with a number of features. First, it provides low propagation delay,typically less than 5ps, making it suitable for high speed applications such as memory and DDR interfaces. The second feature is its high-drive capability, which allows it to source as well as sink large amounts of current. This means it can easily interface with loads that require high current drive. The third feature is its enhanced ESD protection on the I/O pins, enabling robust protection against ESD events. On top of that, the device is also equipped with a low-power standby mode, and the output will be disabled when the input clock reference is less than 11.5Mhz.In summary, the PE49FCT32806HE is an ideal solution for applications that require precise clock generation with minimal variation over time. Its low propagation delay and high-drive capability make it ideal for high speed applications such as memory, DDR interfaces and digital surround sound systems. It is also equipped with enhanced ESD protection, making it ideal for use in environments with a high amount of electrostatic discharge. In addition, it offers low power consumption when in standby mode, making it a cost-effective solution for clock generation.
