Notes:

1.

Internally AC coupled. Data pins connect directly to the CDR.

2.

20 – 80%. Measured with Module Compliance Test Board and OMA test pattern. Use of four 1’s and four 0’s

sequence in the PRBS 9 is an acceptable alternative. SFF-8431 Rev 4.1.

3.

LOS is an open collector output. Should be pulled up with 4.7k

 – 10k on the host board. Normal operation is

logic 0; loss of signal is logic 1.

See Section 2.8.3 of SFF-8431 Rev 4.1.

Measured at 85

C, 3.3V and beginning of life.
