General Description
The SM802105 is a member of the ClockWorks
family of
devices from Micrel and provides an extremely low-noise
timing solution for 10GbE Ethernet 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 156.25MHz or
312.5MHz. There are normally two clock outputs but one
output can be achieved by powering down the second
output with the OE pin. The SM802105 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 or two LVPECL clock outputs at
156.25MHz or 312.5MHz
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
10Gigabit Ethernet
