MPC9239 - 900 MHz Low Voltage LVPECL Clock Synthesizer

General Description

The internal crystal oscillator uses the external quartz crystal as the basis of its frequency reference.

The frequency of the internal crystal oscillator or external reference clock signal is multiplied by the PLL.

The VCO within the PLL operates over a range of 800 to 1800 MHz.

Key Features

  • 3.125 MHz to 900 MHz synthesized clock output signal Differential LVPECL output LVCMOS compatible control inputs On-chip crystal oscillator for reference frequency generation Alternative LVCMOS compatible reference input 3.3 V power supply Fully integrated PLL Minimal frequency overshoot Serial 3-wire programming interface Parallel programming inte.
