Femtoclocks® Crystal-to-3.3V  
LVPECL Frequency Synthesizer  
843004-01  
Data Sheet  
GENERAL DESCRIPTION  
FEATURES  
The 843004-01 is a 4 output LVPECL synthesizer optimized to  
generate Ethernet reference clock frequencies and is a member  
of the family of high performance clock solutions from IDT. Using  
a 25MHz 18pF parallel resonant crystal, the following frequencies  
can be generated based on the settings of 2 frequency select pins  
(F_SEL[1:0]): 156.25MHz, 125MHz, 62.5MHz. The 843004-01  
• Four 3.3V LVPECL outputs  
• Selectable crystal oscillator interface  
or LVCMOS/LVTTL single-ended input  
• Supports the following output frequencies:  
156.25MHz, 125MHz and 62.5MHz  
rd  
uses IDT’s 3 generation low phase noise VCO technology and  
• VCO range: 560MHz - 680MHz  
can achieve 1ps or lower typical rms phase jitter, easily meeting  
Ethernet jitter requirements.The 843004-01 is packaged in a small  
24-pin TSSOP package.  
• RMS phase jitter @ 156.25MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.57ps (typical)  
• RMS phase noise at 156.25MHz (typical)  
Phase noise:  
Offset  
Noise Power  
100Hz ................-95.5 dBc/Hz  
1kHz .................-118 dBc/Hz  
10kHz .................-126 dBc/Hz  
100kHz ..............-126.6 dBc/Hz  
• Full 3.3V supply mode  
• -30°C to 85°C ambient operating temperature  
• Available in lead-free RoHS compliant package
