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.

This table shows the environmental specifications for the product.

This section shows the range of values for normal operation. The host board power supply filtering should be designed as recommended in the SFF Committee Spec.

1. Internal temperature readout through DDMI of up to 75°C is allowed.

Notes:

1. Multiple clock domains are supported only on line-side Rx. Host side Rx supports a single clock domain only.

2. QSFP Tx CDR lock can only occur if Tx lane 4 is transmitting data.

For configurations tested with the AOCs please refer to the system level product (SLP) qualification report.

The DDM functions are implemented according to SFF-8636 for reading the following key parameters with associated warning and alarm thresholds:

• Temperature with warning/alarm

• Supply voltage with warning/alarm

• Laser bias current with warning/alarm

• Transmitted optical power with warning/alarm

• Received optical power with warning/alarm

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.
