Specifications
Absolute maximum ratings are those beyond which damage to the device may occur.
Prolonged operation between the operational specifications and absolute maximum ratings is not intended and may cause permanent device degradation.

The receiver’s performance may degrade due to overload if the maximum values for AOP or OMA are exceeded. The damage threshold is specified in the Absolute Maximum Ratings table above.
The MMA1T00 transceiver supports rate select, which is controlled by writing to registers 0x57-0x58. Two bits are assigned for each receiver lane in byte 0x57 (87dec, Rxn_Rate_Select) and two bits for each transmitter lane in byte 0x58 (88dec, Txn_Rate_Select) to specify up to four bitrates, as defined in SFF-8636 Rev 2.9.2 Table 6-5 XN_RATE_SELECT ENCODINGS. All four lanes are required to have the same rate select value.
The below table specifies the rate for each rate select setting.
Rate Select Encodings

01 | 10.31250 NRZ |
10 | 25.78125 NRZ |
