MPC92429

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order Number: MPC92429/D Rev 0, 09/2003 400 MHz Low Voltage PECL Clock Synthesizer The MPC92429 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 25 MHz to 400 MHz and the support of differential PECL output signals the device meets the needs of the most demanding clock applications. MPC92429 400 MHZ LOW VOLTAGE CLOCK SYNTHESIZER Features 25 MHz to 400 MHz synthesized clock output signal Differential PECL output LVCMOS compatible control inputs On-chip crystal oscillator for reference frequency generation 3.3V power supply Fully integrated PLL Minimal frequency overshoot Serial 3-wire programming interface Parallel programming interface for power-up 32 lead LQFP and 28 PLCC packaging SiGe Technology Ambient temperature range 0°C to +70°C Pin and function compatible to the MC12429 and MPC9229 FA SUFFIX 32 LEAD LQFP PACKAGE CASE 873A FN SUFFIX 28-LEAD PLCC PACKAGE CASE 776 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 is divided by 16 and then multiplied by the PLL. The VCO within the PLL operates over a range of 200 to 400 MHz. Its output is scaled by a divider that is configured by either the serial or parallel interfaces...
