General Description
The SM843001-212 is a Fibre Channel, 212.5MHz
LVPECL clock frequency synthesizer and a member of the
ClockWorks
family of devices from Micrel. It provides a
low-noise timing solution for high-speed, high-accuracy
synthesis of clock signals. It includes a patented
RotaryWave
architecture that provides a stable clock with
very low phase noise.
Power supplies of either 2.5V or 3.3V are supported, with
superior jitter and phase noise performance. The device
synthesizes a 212.5MHz, low-noise, LVPECL output for
Fibre
Channel
applications.
The
crystal
reference
frequency used is 26.5625MHz.
The SM843001-212 is an excellent replacement for IDT
FemtoClocks, with improved waveform integrity, and
jitter.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
