    Functional Description
    The 100G QSFP28 LR4 optical receiver integrates receive path onto one module. The receiver four lanes of optical data
    streams are optically demultiplexed by an integrated optical demultiplexer. Each data steam is recovered by a PIN photodetector and
    transimpedance amplifier, retimed, and passed on to an output driver. This module features a hot-pluggable electrical interface, low
    power consumption, and 2-wire serial interface.


    Notes:
    1: GND is the symbol for signal and supply (power) common for the module. All are common within the module and all module voltages are
    referenced to this potential unless otherwise noted. Connect these directly to the host board signal-common ground plane.
    2: Vcc Rx, Vcc1 and Vcc Tx shall be applied concurrently. Vcc Rx Vcc1 and Vcc Tx may be internally connected within the module in any
    combination. The connector pins are each rated for a maximum current of 1000 mA. Recommended host board power supply filtering is shown
    below .
    3: 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.
    4: 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.
    5: Low speed signaling other than SCL and SDA is based on Low Voltage TTL (LVTTL) operating at Vcc. Vcc refers to the generic supply
    voltages of VccTx, VccRx, Vcc_host or Vcc1.
    Hosts shall use a pull-up resistor connected to Vcc_host on each of the 2-wire interface SCL (clock), SDA (data), and all low speed status outputs.
    The SCL and SDA is a hot plug interface that may support a bus topology. 6: 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.
    7: 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 2-wire 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).
    8: 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, Power_set and
    High_Power_Class_Enable software control bits (Address A0h, byte 93 bits 0,1,2), the host contrHLS how much power a module can dissipate.
    9: Rx(n)(p/n) are module receiver data outputs. Rx(n)(p/n) are AC-coupled 100 Ohm differential lines that should be terminated with 100 Ohm
    differentially at the Host ASIC(SerDes). The AC coupling is inside the module and not required on the Host board. For operation at 28 Gb/s the
    relevant standards (e.g., OIF CEI v3.1) define the signal requirements on the high-speed differential lines. For operation at lower rates, refer to the
    relevant standards.
    Note: Due to the possibility of insertion of legacy QSFP and QSFP+ modules into a host
    designed for higher speed operation, it is recommended that the damage threshold of the host input be at least 1600 mV peak to peak differential.
    Output squelch for loss of optical input signal, hereafter Rx Squelch, is required and shall function as follows. In the event of the optical signal on
    any channel becoming equal to or less than the level required to assert LOS, then the receiver data output for that channel shall be squelched or
    disabled. In the squelched or disabled state output impedance levels are maintained while the differential voltage swing shall be less than 50 mVpp.
    In normal operation the default case has Rx Squelch active. Rx Squelch can be deactivated using Rx Squelch Disable through the 2-wire serial
    interface. Rx Squelch Disable is an optional function. For specific details refer to SFF-8636.
    10: Tx(n)(p/n) are module transmitter data inputs. They are AC-coupled 100 Ohm differential lines with 100 Ohm differential terminations inside
    the module. The AC coupling is inside the module and not required on the Host board. For operation at 28 Gb/s the relevant standards (e.g., OIF
    CEI v3.1) define the signal requirements on the high-speed differential lines. For operation at lower rates, refer to the relevant standards. Due to
    the possibility of insertion of modules into a host designed for lower speed operation, the damage threshold of the module input shall be at least
    1600 mV peak to peak differential. Output squelch, hereafter Tx Squelch, for loss of input signal, hereafter Tx LOS, is an optional function. Where
    implemented it shall function as follows. In the event of the differential, peak-to-peak electrical signal on any channel becomes less than 50 mVpp,
    then the transmitter optical output for that channel shall be squelched or disabled and the associated TxLOS flag set. Where squelched, the
    transmitter OMA shall be less than or equal to -26 dBm and when disabled the transmitter power shall be less than or equal to -30 dBm. For
    applications, e.g. Ethernet, where the transmitter off condition is defined in terms of average power, disabling the transmitter is recommended and
    for applications, e.g. InfiniBand, where the transmitter off condition is defined in terms of OMA, squelching the transmitter is recommended. In
    module operation, where Tx Squelch is implemented, the default case has Tx Squelch active. Tx Squelch can be deactivated using Tx Squelch
    Disable through the 2-wire serial interface. Tx Squelch Disable is an optional function. For specific details refer to SFF- 8636.
