PI6C4511 PLL Clock Multiplier Features Description • • • • • • • • • The PI6C4511 is a high performance frequency multiplier, that integrates analog Phase Lock Loop (PLL). Zero ppm multiplication error Input crystal frequency range: 5 - 30 MHz Input clock frequency range: 4 - 50 MHz Output clock frequencies up to 200 MHz Period jitter ≤ 150ps 9 selectable frequencies Operating voltages: 3.3V ±10% and 5.0V ±10% Tri-state output Packaging (Pb-Free and Green): —8-pin SOIC (W) The PI6C4511 is the most cost effective way to generate a high quality, high frequency clock output from a crystal input or clock input. It is designed to replace crystal oscillators in electronic systems, or to be used as clock multiplier and frequency translation. The complex logic divider generates nine different popular multiplication factors, allowing the device to produce output of many common frequencies. The device also has an Output Enable pin that tri-states the clock output. The PI6C4511 is intended for applications that needed clock generation and frequency translation with low output jitter.
