Seagate ST3600002SS, ST3450802SS manual X2OP 0, 5xadditional sinusoidal jitter X1OP

Page 59

The leading and trailing edge slopes of figure 14 shall be preserved. As a result the amplitude value of Z1 is

less than that given in table 26 and Z1TOL and Z1OP shall be defined from those slopes by the following equa-

tion:

 

X2OP ((0, 5)xadditional sinusoidal jitter) X1OP

Z1TOL

= Z1OPx

----------------------------------------------------------------------------------------------------------------------------------X2OPX1OP

where:

 

 

 

Z1TOL is the value for Z1 to be used for the tolerance masks; and

Z1OP, X1OP, and X2OP are the values in table 26 for Z1, X1, and X2.

The X1 points in the receive tolerance masks are greater than the X1 points in the receive masks, due to the addition of sinusoidal jitter.

Figure 16 defines the sinusoidal jitter mask.
