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.
4. See Section 2.8.3 of SFF-8431 Rev 4.1.
5. Typical power consumption values refer to 3.3V, 70C case temperature and beginning of life.
