Absolute Maximum 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.

- Multiple clock domains are supported only on the line-side Rx. Host side Rx supports a single clock domain only.
- QSFP Tx CDR lock can only occur if Tx lane 4 is transmitting data.
Electrostatic Discharge (ESD)
This product is compatible with ESD levels in typical data center operating environments and certified in accordance with the standards listed in the Regulatory Compliance Section. The product is shipped with protective caps on all connectors to protect it during shipping. In normal handling and operation of high-speed cables and optical transceivers, ESD is of concern during insertion into the OSFP cage of the server/switch. Hence, standard ESD handling precautions must be observed. These include use of grounded wrist/shoe straps and ESD floor wherever a cable/transceiver is extracted/inserted. Electrostatic discharges to the exterior of the host equipment chassis after installation are subject to system level ESD requirements.
For configurations tested with the AOCs please refer to the system level product (SLP) qualification report.
The AOC 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.

FCC Class A Notice
Each of the devices complies with CFR47 FCC Class A Part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference.
- This device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur during installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/television technician for help.
Modifications: Any modifications made to this device that are not approved by NVIDIA may void the authority granted to the user by the FCC to operate this equipment.
