PI6LC58S1101 HiFlex™ Clock Generator Diodes Incorporated PI6LC58S1101 HiFlex™ Clock Generator is a very low jitter clock generator designed for applications that demand extremely low phase noise. This clock generator utilizes the proprietary LC VCO-based PLL design to achieve an optimum combination of popular networking clock frequencies. This technology also helps in achieving low phase noise performance along with high power supply noise rejection. The PI6LC58S1101 clock generator features four output banks which can be configured independently for different frequencies and different output signaling types based on control pins. This clock generator offers 25MHz/50MHz crystal/CMOS input, 25MHz/50MHz differential input, four output banks with selectable output signaling, and very low RMS phase jitter.
