MOTOROLA Freescale Semiconductor, Inc. SEMICONDUCTOR TECHNICAL DATA Order Number: MPC9259/D Rev 0, 12/2002 Preliminary Information 900 MHz Low Voltage LVDS Clock Synthesizer MPC9259 The MPC9259 is a 3.3V compatible, PLL based clock synthesizer targeted for high performance clock generation in mid-range to high-performance telecom, networking and computing applications. With output frequencies from 50 MHz to 900 MHz and the support of differential LVDS output signals the device meets the needs of the most demanding clock applications. Features 900 MHZ LOW VOLTAGE CLOCK SYNTHESIZER 50 MHz to 900 MHz synthesized clock output signal Freescale Semiconductor, Inc... Differential LVDS output LVCMOS compatible control inputs On-chip crystal oscillator for reference frequency generation Alternative LVCMOS compatible reference input 3.3V power supply Fully integrated PLL Minimal frequency overshoot Serial 3-wire programming interface Parallel programming interface for power-up 32 Pin LQFP Package SiGe Technology Ambient temperature range 0°C to + 70° C Functional 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. Its output is scaled by a divider that is configured by either the serial or parallel interfaces. Th...
