The MPC9448ACR2 is a state-of-the-art clock buffer/driver device designed to serve as an industry-standard clock tree solution for the most demanding applications. It is a multi-output low-cost PLL based clock driver IC, which enables users to reduce design complexity and cost by using dual-lane output buses. The device is a versatile and reliable clock buffer/driver with 25 insertion delays, five preset outputs, one differential output, and low jitter performance. The MPC9448ACR2 also features power management, diagnostics, and frequency security features such as clock/data gating.

The MPC9448ACR2 can be used in a wide range of applications, even in high-performance applications. It supports up to 25 time-aligned outputs, with a single reference clock, which makes clock tree design much easier. By employing an external crystal reference clock, the device offers very low-jitter performance with better than 50 ps jitter across a wide input frequency range. Additionally, the MPC9448ACR2 offers a variety of output configurations, such as single-ended, differential and multi-lane differential, allowing a range of applications to benefit of its unique features.

The MPC9448ACR2 operates by dividing the input clock frequency by a programmable divider. Low-jitter clock outputs are typically obtained through the use of an on-chip charge-pump oscillator or an external programmable loop filter. The divider and loop filter are used to control the output frequency of the device. Additionally, the device enables users to program the duty cycle of the clock output to match the desired frequency output specification.

The MPC9448ACR2 also features power saving features like power-down mode, frequency gating and spread spectrum clock output to reduce EMI/RFI. The device also features various diagnostic features to detect problems in the output clock frequencies. These features further increase the reliability and accuracy of the clock output.

In summary, the MPC9448ACR2 is a high-performance low-cost clock buffer/driver device that offers several advanced features such as low-jitter performance, power management, diagnostics, and frequency gating. The device is ideal for a wide range of applications and can reliably provide lower power consumption and improved fidelity of the clock signal. With its 25 insertion delays, five preset outputs, one differential output, and low jitter performance, the device provides an excellent choice for customers looking for a reliable clock buffer/driver solution.
