General Description
The SM802111 is a member of the ClockWorks
family of
devices from Micrel and provides an extremely low-noise
timing solution for Gigabit 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 two LVPECL output clocks at 125MHz.
The SM802111 accepts a 15MHz LVCMOS reference
clock.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
Features
Generates two LVPECL clock outputs at 125MHz
2.5V or 3.3V operating range
Typical phase jitter @ 125MHz
(1.875MHz to 20MHz): 85fs (typical) at 3.3V
Industrial temperature range
Green, RoHS, and PFOS compliant
Available in 24-pin 4mm × 4mm QFN
Applications
Gigabit Ethernet
