SM840051  
10 Gigabit Ethernet Ultra-Low Jitter Clock  
Synthesizer  
General Description  
Features  
The SM840051 clock synthesizer was designed for  
Ethernet standards. The SM840051 is optimized for 77.76,  
78.125, 80.56, 155.52, 156.25, and 161.13MHz, using a  
crystal at 1/8th the output frequency. The SM840051  
includes a unique power reduction methodology, along  
with a patented RotaryWave™ architecture, that provides  
a stable clock with very low noise for optimized  
performance. This yields an overall improved Bit Error  
Rate (BER) and improved waveform integrity.  
Generates a single LVCMOS/LVTTL output  
Output Frequencies: 77.76, 78.125, 80.56, 155.52,  
156.25, and 161.13MHz  
RMS Phase Jitter at 156.25MHz( 1.875MHz-20MHz):  
58fs (typical)  
Integrated loop filter components  
Operates with either a 3.3V or 2.5V supply  
Power consumption is <77mA @ 3.3 V  
Fundamental parallel resonant crystal  
Power supplies of either 3.3V or 2.5V are supported, with  
superior jitter and phase noise performance. An FSEL pin  
supports 4x or 8x multiplication of the crystal frequency.  
Crystal Frequencies: 20.141601MHz,19.53125MHz, and  
19.44MHz  
The SM840051 provides ultra-low jitter, and consumes low  
power.  
Industrial temperature range: –40°C to +75°C  
Available in 8-pin TSSOP package  
Datasheets and support documentation can be found on  
Micrel’s web site at: www.micrel.com.  
Applications  
10 Gigabit Ethernet  
SONET/SDH
