Differential LVDS Crystal Clock Oscillators LVDS Outputs  
3HDF5761 Series +3.3V, “F” family  
MERCURY  
Since 1973  
3HDF5761 products feature 0.4 ps typical phase jitter and  
low phase noise (-132 dBc at 10 KHz for 155.520 MHz).  
Differential LVDS Outputs meet the requirements for  
SONET, XDSL and other communication protocols.

No Connection  
Differential LVDS and complimentary LVDS outputs.  
Both outputs are disabled (high impedance) when pad No. 2 is taken  
below 0.45Vcc referenced to ground (threshold). Oscillator is always  
ON. Only buffer stage is disabled.  
Disable current: 50 uA max. (at 0.0 V).  
Disable time: 10 ns max.  
At disabled mode, both outputs are enabled when pad No. 2 is taken  
above 0.45Vcc referenced to ground (threshold).  
Enable time: 10ns+one period of the output frequency max.
