It is designed to provide low clock skew and specific propagation delays for each of the sixteen outputs.

The PCK9446BD\'s working principle is based on a simple concept; the input clock is buffered and routed to the outputs. It uses an internal PLL (Phase Locked Loop) to provide low jitter, low noise and low clock skew while providing superior signal integrity.The PCK9446BD utilizes an input diode array that helps reduce the input voltage range. This allows the device to support a wide variety of input signals, including both CMOS and TTL, as well as signals from a crystal oscillator. The input diode array also increases noise rejection which results in cleaner distributed clocks. The device also utilizes a low-skew output buffer array that reduces jitter and provides noise immunity.

The PCK9446BD also includes built-in programmable functions that can be used to precisely control the output timing characteristics. It can be used to create skew compensation, output delays, and output compensation. With these features, the device can be used to improve the synchronization between clock signals and data inputs or between boards. The device also includes an integrated adjustable feedback loop to ensure maximum performancein critical applications.

In conclusion, the PCK9446BD is a powerful clock buffer, driver, and fan-out buffer designed to provide superior signal integrity, low latency and superior performance in critical synchronous applications. It is well suited for use in a variety of applications that require improved clock and signal integrity.
