SM802104

www.DataSheet.co.kr SM802104 ClockWorks™ Fibre Channel (106.25MHz, 212.5MHz), Ultra-Low Jitter, LVPECL Frequency Synthesizer General Description The SM802104 is a member of the ClockWorks™ family of devices from Micrel and provides an extremely low-noise timing solution for Fibre Channel clock signals. It is based upon a unique, patented RotaryWave® architecture that provides very low phase noise. The device operates from a 3.3V or 2.5V power supply and synthesizes LVPECL output clocks at 106.25MHz or 212.5MHz. There are normally two clock outputs, but one output can be achieved by powering down the second output with the OE pin. The SM802104 accepts a 26.5625MHz 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 or two LVPECL clock outputs at 106.25MHz or 212.5MHz 2.5V or 3.3V operating range Typical phase jitter @ 106.25MHz (637kHz to 10MHz): 200fs Industrial temperature range Green, RoHS, and PFOS compliant Available in 24-pin 4mm × 4mm QFN package Applications Fibre Channel Storage Networking (SAN, NAS) Block Diagram ClockWorks is a trademark of Micrel, Inc RotaryWave is a registered trademark of Multigig, Inc.
