General Description
The SM802128 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
eight
LVPECL
output
clocks
at
156.25MHz or 312.5MHz. The SM802128 accepts a 25
MHz crystal or LVCMOS reference clock.
Data sheet and support documentation can be found on
Micrel’s web site at: www.micrel.com.
Features
Generates eight LVPECL clocks at 156.25MHz or
312.5MHz
2.5V or 3.3V operating range
Typical phase jitter @ 156.25MHz
(1.875MHz to 20MHz): 110fs with crystal reference
Industrial temperature range (–40°C to +85°C)
Green, RoHS, and PFOS compliant
Available in 44-pin 7mm × 7mm QFN package
