Pericom Semiconductor PI6C2502
The PI6C2502 features a low-skew, low-jitter, phase-locked loop (PLL) clock driver. By connecting the feedback FB_OUT output to the feedback FB_IN input, the propagation delay from the CLK_IN input to any clock output will be nearly zero. The device-to-device skew introduced can significantly reduce the performance.FEATURES

● Wide range of Clock Frequencies up to 80 MHz
● Package: Plastic 8-pin SOIC Package (W) Product
DESCRIPTION
Application If a system designer needs more than 16 outputs with the features just described, using two or more zero-delay buffers such as PI6C2509Q, and PI6C2510Q, is likely to be impractical. 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.
