The CDCP1803 clock driver distributes one pair of differential clock inputs to three pairs of LVPECL differential  
clock outputs Y[2:0] and Y[2:0], with minimum skew for clock distribution. The CDCP1803 is specifically  
designed for driving 50-transmission lines.  
The CDCP1803 has three control pins, S0, S1, and S2, to select different output mode settings, see Table 1  
for details. The CDCP1803 is characterized for operation from −40°C to 85°C. For use in single-ended driver  
applications, the CDCP1803 also provides a VBB output pin that can be directly connected to the unused input  
as a common-mode voltage reference.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
