DESCRIPTION/ORDERING INFORMATION  
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 terminals, S0, S1, and S2, to select different output mode settings; see Table 1  
for details. The CDCP1803 is characterized for operation from –55°C to 125°C. For use in single-ended driver  
applications, the CDCP1803 also provides a VBB output terminal that can be directly connected to the unused  
input as a common-mode voltage reference.
