The high speed DATA interface is differential AC-coupled internally and can be directly connected to a 3.3V SERDES IC. Hardware control and status reporting pins include a 2-wire serial interface (SCL and SDA) and five 3.3V LVTTL hardware signals (ModSelL, ResetL, LPMode, ModPrsL, and IntL). The 2-wire interface pins are 3.3V LVCOMS compatible. Hosts shall use pull-up resistor connected to Vcc_host on each of the 2-wire interface SCL, SDA, and all low speed status outputs. ModSelL: The ModSelL is an input pin. When held low by the host, the module responds to 2-wire serial communication commands. The ModSelL allows the use of multiple modules on a single 2-wire interface bus. When the ModSelL is "High", the module shall not respond to or acknowledge any 2-wire interface communication from the host. ModSelL signal input node shall be biased to the "High" state in the module. In order to avoid conflicts, the host system shall not attempt 2-wire interface communications within the ModSelL de- assert time after any modules are deselected. Similarly, the host shall wait at least for the period of the ModSelL assert time before communicating with the newly selected module. The assertion and de-asserting periods of different modules may overlap as long as the above timing requirements are met. ResetL: The ResetL pin shall be pulled to Vcc in the module. A low level on the ResetL pin for longer than the minimum pulse length (t_Reset_init) initiates a complete module reset, returning all user module settings to their default state. Module Reset Assert Time (t_init) starts on the rising edge after the low level on the ResetL pin is released. During the execution of a reset (t_init) the host shall disregard all status bits until the module indicates a completion of the reset interrupt. The module indicates this by asserting "low" an IntL signal with the Data_Not_Ready bit negated. Note that on power up (including hot insertion) the module should post this completion of reset interrupt without requiring a reset. LPMode: The LPMode pin shall be pulled up to Vcc in the module. The pin is a hardware control used to put modules into a low power mode when high. By using the LPMode pin and a combination of the Power_override, and Power_set software control bits (Address A0h, byte 93 bits 0,1), the host controls how much power a module can dissipate. The allowed QSFP28 power consumption is shown in below truth table. LPMode PIN State Power_override bit Power_set bit Power Allowed 1 0 X 1.5W 0 0 X 4.5W X 1 1 1.5W X 1 0 4.5W ModPrsL: ModPrsL is pulled up to Vcc_Host on the host board and grounded in the module. The ModPrsL is asserted "Low" when inserted and deasserted "High" when the module is physically absent from the host connector. IntL: IntL is an output pin. When IntL is "Low", it indicates a possible module operational fault or a status critical to the host system. The host identifies the source of the interrupt using the 2wire serial interface. The IntL pin is an open collector output and shall be pulled to host supply voltage on the host board. The INTL pin is deasserted "High" after completion of reset, when byte 2 bit 0 (Data Not Ready) is read with a value of '0' and the flag field is read (see SFF-8636). VI. Ntearcing the Transceiver Host can determine the characteristic and status of the transceiver through a 2-wire common management interface. The interface also provides host a mechanism to control the operation of a module. SFF-8636 describes the interface details such as memory map and communication protocol used to transfer information between host and a module. The common memory map is arranged into a single lower page address space (A0h) of 128 bytes and multiple upper address pages. This structure permits timely access to addresses in the lower page such as interrupt flags and monitors. Less time critical entries such as serial ID information and threshold settings are available with the page select function.

ESD This transceiver is specified as ESD threshold 1kV for high speed data pins and 2kV for all other electrical input pins, tested per MIL-STD-883, Method 3015.4 /JESD22-A114-A (HBM). However, normal ESD precautions are still required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment. X. Laser Saftey This is a Class 1 Laser Product according to EN/IEC 60825-1:2014.
