HOW MAJOR PATTERN B IS SYNTHESIZED
MAJOR PATTERN B is created (by the Mapper IC) by:
Repeating MINOR PATTERN P1 (e.g., 7 clock pulses, followed by a gap) 63 times.
Upon completion of the 63rd transmission of MINOR PATTERN P1, MINOR PATTERN P2 is transmitted
repeatedly 36 times.
pon completion of the 35th transmission of MINOR PATTERN P2, MINOR PATTERN P3 is transmitted once.
Figure 70 presents an illustration which depicts the procedure that is used to synthesize MAJOR PATTERN B.
Hence, MAJOR PATTERN B consists of "(63 x 7) + (35 x 5)" + 6 = 622 clock pulses.
These 622 clock pulses were delivered over a period of "(63 x 8) + (35 x 6) + 6 = 720 STS-1 (or 51.84MHz)
clock periods.
PUTTING THE PATTERNS TOGETHER
Finally, the DS3 to OC-N Mapper IC clock output is reproduced by doing the following.
MAJOR PATTERN A is transmitted two times (repeatedly).
After the second transmission of MAJOR PATTERN A, MAJOR PATTERN B is transmitted once.
Then the whole process repeats.
Throughout the remainder of this document, we will refer to this particular pattern as the "SUPER PATTERN".
Figure 71 presents an illustration of this "SUPER PATTERN" which is output via the Mapper IC.
