Phase-Locked Loop Clock Driver

ProductFeatures

Product Description

The PI6C2501 features a low-skew, low-jitter, phase-locked loop

(PLL) clock driver. By connecting the CLK_OUT output to the

feedback FB_IN input, the propagation delay from the CLK_IN

input to CLK_OUT output will be nearly zero.

• High-Performance,Phase-Locked-LoopClockDistribution

• Allows Clock Input to have Spread Spectrum modulation

for EMI reduction

• Zero Input-to-Output delay

• Lowjitter:Cycle-to-Cyclejitter±100psmax.

Application

• On-chip series damping resistor at clock output drivers

for low noise and EMI reduction

If a system designer needs more than 16 outputs with the features

just described, using two or more zero-delay buffers, such as the

PI6C2509Q, or PI6C2510Q, is likely to be impractical. The

device-to-device skew introduced can significantly reduce the

performance. Pericom recommends using 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.

• Operatesat3.3VV_CC

• Wide range of Clock Frequencies up to 80 MHz

• Package:Plastic8-pinSOIC(W)
