Phase-Locked Loop Clock Driver
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_IN input to any clock output will be nearly zero.The PI6C2402
provides 2X CLK_IN on CLK_OUT output.
Applications
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.
