SFP+ Transceiver Electrical Pad Layout
Pin Function Definitions
Notes:
1.Tx_Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor on the host board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
2.Tx_disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a resistor in the range 4.7 kΩ to 10 kΩ. Its states are:
Low (0 – 0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
3. RS0 and RS1 are module inputs and are pulled low to VeeT with > 30 kΩ resistors in the module. RS0 optionally selects the optical receive signaling rate coverage. RS1 optionally selects the optical transmit signaling rate coverage.
These contacts can also be used for AS0 and AS1 if implementing SFF8079. See SFF8079 for details. RS1 is commonly connected to VeeT or VeeR in the classic SFP modules. The host needs to ensure that it will not be damaged if this contact is connected to VeeT or VeeR in the module.
The SFP+ module provides two inputs RS0 and RS1 that can optionally be used for rate selection. RS0 controls the receive path signalling rate capability, and RS1 controls the transmit path signalling rate capability. The host and module may choose to use either, both, or none of these functions. Because contact 9 in the classic SFP INF-8074i is connected to VeeR, an SFP+ host utilizing RS1 must provide short circuit protection.
This rate select functionality can also be controlled by software as defined by SFF-8472. Optionally the rate select methods of Part 2 of SFF-8079 may be used instead of the method described here by setting the management declaration bit (A0h byte 93 bit 2) to 1, see SFF-8472.
4. Rx_LOS when high indicates an optical signal level below that specified in the relevant standard. Rx_LOS is an open
drain/collector output, but may also be used as an input by supervisory circuitry in the module. For a nominally 3.3 V Vcc_Host using a
resistive pull up to Vcc_Host the resistor value shall be in the range 4.7 kΩ to 10 kΩ. For a nominally 2.5 V Vcc_Host using a resistive
pull up to Vcc_Host the resistor value shall be in the range 4.7 kΩ to 7.2 kΩ.
The Rx_LOS signal is intended as a preliminary indication to the host in which the module is installed that the received signal
strength is below the specified range. Such an indication typically points to non-installed cables, broken ca-bles, or a disabled,
failing or a powered off transmitter at the far end of the cable. Additional indications are provided by the host in which the module is
installed to verify that the information being transmitted is valid, correctly en-coded, and in the correct format. Such additional
indications are outside the scope of the module specification.
Rx_LOS may be an optional function depending on the supported standard. If the Rx_LOS function is not implemented, or is
reported via the two-wire inter-face only, the Rx_LOS contact shall be held low by the module and may be con-nected to Vee
within the module.
Rx_LOS assert min and de-assert max are defined in the relevant standard. To avoid spurious transition of Rx_LOS a minimum
hysteresis of 0.5 dBo is recom-mended.
5.VeeR and VeeT : The module signal ground contacts, which should be isolated from the module case and which may be internally
connected within the SFP module.
6. RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with
100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board.
7.VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±10% at the SFP+ connector pin.
Maximum supply current is 300mA. Recommended host board power supply filtering is shown below.
Monitor Specification
The digital diagnostic monitoring interface also defines another 256-byte memory map in EEPROM, which makes use of the 8 bit address 1010001X (A2h). The monitoring specification of this product is described in this table.
