Notes:
1. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and VCC.
2. For Rate Selectable version only: In accordance with SFF Committee SFF-8079 Draft Rev. 1.6,
Table 3. Note that rate select can also be set through 2-wire bus in accordance with SFF-84725 at Bit
3, Byte 110, Address A2h (note: writing ‘1’ selects full bandwidth operation). Rate select is the logic
OR of the input state of Rate Select Pin and 2-wire bus. Non Rate Selectable version can operate at 1x,
2x, 4x Fibre Channel independent of rate select pin setting.
