It is based upon a unique patented RotaryWave ® architecture that provides very-low phase noise. The device operates from a 2.5V or 3.3V power supply and synthesizes an LVPECL output clock at 156.25MHz. The SM802121 accepts a 25MHz crystal or LVCMOS reference clock. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com. Features Generates one LVPECL clock outputs at 156.25MHz 2.5V or 3.3V operating range Typical phase jitter @ 156.25MHz (1.875MHz to 20MHz): 110fs Industrial temperature range Green, RoHS-, and PFOS- compliant Available in 24-pin 4mm 4mm QFN package Applications 10 Gigabit Ethernet Block Diagram |
