The PI6C10804WEX is a high-performance clock buffer that can provide four outputs with consumer-based applications. It is used to replicate an input clock signal into multiple, low-skew outputs, and is especially suitable for driving high-speed memory buses, networking functions, and other synchronous intensive applications. This clock buffer features low jitter and low power consumption and comes in a standard 24-pin VQFN package.

The PI6C10804WEX follows the same recommendation as the other versions of the PI6C clock buffer family. It is ideally suited for clock buffering applications such as memory controllers, refclocks, PCI Express, and SAS controllers, as well as fan-out and multiphase clock operations.

Application Field and Working Principle

The PI6C10804WEX clock buffer is a low-skew, high performance device designed for consumer electronic applications. This device is intended for use in applications such as memory controllers, refclocks, PCI Express, and SAS controllers where signal integrity and frequency synchronization are of utmost importance.

The working principle of the PI6C10804WEX is based on a “shift-up” design which provides an optimal signal-to-noise ratio. The device contains a primary oscillator and buffer cells which allow the primary oscillator to buffer different output signals based on their input frequency. This “shift-up” technique is employed to ensure clock signals remain in phase with each other, even when subjected to temperature, voltage, or supply variations. The shift-up technique also helps reduce jitter, thereby enabling improved signal quality in critical applications.

The PI6C10804WEX is capable of generating low-skew, highly accurate output clocks that can then be used in systems equipped with a variety of communication protocols. The device includes a static frequency and phase control registers, which allow the user to select the desired output frequency, as well as the phase offset between the input and output signals. The registers also allow the user to adjust the output level of the device and enable other features such as skew control and power management.

The PI6C10804WEX is also designed for compatibility with a variety of clock standards and provides high-accuracy frequencies for both LVCMOS and LVDS. The device is able to generate clock signals up to 6.25GHz and is able to provide up to three output signals per each input channel. The PI6C10804WEX also has an internal temperature compensation mechanism which allows it to automatically adjust its output signals in real time.

Finally, the device comes with a variety of additional features including slew-controlled outputs, glitchless clock switching, power-saving modes, and adjustable clock skew. The result is a clock buffer that is well-suited for high-speed memory buses, networking functions, and other synchronous intensive applications.
