PI6C2402  
Phase-Locked Loop Clock Driver  
Features  
Description  
The PI6C2402 features a low-skew, low-jitter, Phase-Locked Loop  
(PLL) clock driver. By connecting the feedback CLK_OUT out-  
put to the feedback FB_IN input, the propagation delay from the  
CLK_INinputtoanyclockoutputwillbenearlyzero.ThePI6C2402  
provides 2X CLK_IN on CLK_OUT output.

applications  
Applications  
Zero Input-to-Output delay  
If the system designer needs more than 16 outputs with the fea-  
tures just described, using two or more zero-delay buffers such  
as the PI6C2509, and the PI6C2510, are likely to be impractical.  
The device-to-device skew introduced can signicantly reduce  
the performance. Pericom recommends the use of a zero-delay  
buffer and an eighteen output non-zero-delay buffer. As shown in  
Figure 1, this combination produces a zero-delay buffer with all the  
signal characteristics of the original zero-delay buffer, but with as  
many outputs as the non-zero-delay buffer part. For example, when  
combined with an eighteen output non-zero delay buffer, a system  
designer can create a seventeen-output zero-delay buffer.  
Cycle-to-Cycle jitter ±150ps max.
