SM802XXX Flexible Ultra-Low Jitter Clock Synthesizer Features General Description 115 fs at 156.25 MHz (1.875 MHz to 20 MHz) The SM802xxx series is a member of the ClockWorks family of devices from Microchip and provide an 265 fs at 156.25 MHz (12 kHz to 20 MHz) extremely low-noise timing solution for applications On-Chip Power Supply Regulation for Excellent such as (1-100) Gigabit Ethernet, SONET, wireless Board-Level Power Supply Noise Immunity base station, satellite communication, Fibre Channel, Generates up to 8 Combinations of Differential or SAS/SATA, and PCIe. It is based upon a unique PLL 16 Single-Ended Clock Outputs architecture that provides less than 250 fs phase jitter. - LVPECL, LVDS, HCSL, LVCMOS (SE or Diff) The devices operate from a 2.5V or 3.3V power supply Selectable Input: and synthesize up to 8 different combinations - Crystal: 11.4 MHz to 27 MHz (LVPECL, LVDS, HCSL) of differential or 16 - Reference Input: 11.4 MHz to 80 MHz single-ended output clocks. The devices accept an external reference clock or crystal input. No External Crystal Oscillator Capacitors Required The SM802xxx series is fully programmable and a web 2.5V or 3.3V Operating Power Supply tool is available to configure a part for samples at the ClockWorks Configurator tool.
