SM843031-01  
ClockWorks10-Gigabit Ethernet,  
312.5MHz, Ultra-Low Jitter LVPECL Clock  
Frequency Synthesizer  
General Description  
Features  
The SM843031-01 is a 10-Gigabit Ethernet, 312.5MHz  
LVPECL clock frequency synthesizer and a member of the  
ClockWorksfamily 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 very stable clock  
with very low noise.  
Generates a low noise LVPECL output  
2.5V or 3.3V operating range  
Typical phase jitter @ 312.5MHz  
(1.875MHz to 20MHz): 119 fs (typical) @ 3.3V  
Crystal frequency: 25MHz  
312.5MHz Output frequency  
Industrial temperature range  
Green-, RoHS-, and PFOS-compliant  
Available in 8-pin TSSOP  
Power supplies of either 2.5V or 3.3V are supported, with  
superior jitter and phase noise performance. The device  
synthesizes a 312.5MHz, low-noise, LVPECL output for  
Ethernet applications. The crystal reference frequency  
used is 25MHz.  
Applications  
The SM843031-01 is an excellent replacement for IDT  
FemtoClocks®, with improved waveform integrity, and jitter.  
Gigabit Ethernet  
10-Gigabit Ethernet
