Additional Details:

The MPC9315FAR2 typically supports a wide range of input reference clock frequencies. The output clock frequencies can be programmed through the I2C interface using programmable dividers. The device features multiple output clock channels, each of which can be configured independently. Important specifications include the output frequency range, the jitter performance (typically specified as RMS jitter or phase noise), the output voltage swing, and the power supply voltage. The device often includes features such as spread spectrum clocking (SSC) to reduce electromagnetic interference (EMI). The MPC9315FAR2 is typically packaged in a small surface-mount package for easy integration into printed circuit boards (PCBs). Careful attention to PCB layout is essential to minimize noise and ensure optimal jitter performance. Freescale (NXP) is a leading supplier of clock management ICs for various applications.
