MPC92469

400 MHz Low Voltage PECL Clock Synthesizer w/Spread Spectrum The MPC92469 is a 3.3 V 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. 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 Spread Spectrum output for EMI reduction 3.3 V power supply Fully integrated PLL Minimal frequency overshoot Serial 3-wire programming interface Parallel programming interface for power-up 32-lead LQFP packaging 32-lead Pb-free package available SiGe Technology Ambient temperature range 0°C to +70°C Pin compatible to the MC12429, MPC9229, MPC92429, and ICS84329 MPC92469 400 MHz LOW VOLTAGE CLOCK SYNTHESIZER w/SPREAD SPECTRUM FA SUFFIX 32-LEAD LQFP PACKAGE CASE 873A-03 AC SUFFIX 32-LEAD LQFP PACKAGE Pb-FREE PACKAGE CASE 873A-03 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 400 to 800 MHz. Its output is scaled by a divider that is...
