Three configurations of fDIN and fREFCLK are considered here and yield these results for CENTER_F, G1, and G2:
•Fast Ethernet (fDIN = 125 Mb/s ± 100 ppm with fREFCLK = 125 MHz ± 100ppm):
CENTER_F = b0000100000000000000000000000000000000 and G1 = G2 ≤ 11.
•Fast Ethernet (fDIN = 125 Mb/s ± 100 ppm with fREFCLK = 155.52 MHz ± 20 ppm):
CENTER_F = b0000011001101110000101110010110101001 and G1 = G2 ≤ 11.
•OC3 (fDIN = 155.52 Mb/s ± 20 ppm with fREFCLK = 125 MHz ± 100 ppm):
CENTER_F = b0000100111110100000010100010100001110 and G1 = G2 ≤ 11.
