Product Description
JHA3401 10/100/1000BASE-T copper SFP transceiver is high performance, cost effective module compliant with the Gigabit Ethernet and 10/100/1000BASE-T standards as specified in IEEE 802. 3-2002 and IEEE 802.3ab, which supporting 10/100/1000Mbps data- rate up to 100 meters reach over unshielded twisted-pair category 5 cable. The JHA3401 supports 10/100/1000 Mbps full duplex data-links with 5-level Pulse Amplitude Modula-tion (PAM) signals. All four pairs in the cable are used with symbol rate at 250Mbps on each pair. The JHA3401 provides standard serial ID information compliant with SFP MSA, which can be accessed with address of A0h via the 2-wire serial CMOS EEPROM protocol. The physical IC can also be accessed via 2-wire serial bus at address ACh. SFP to Host Connector Pin OutPin | Signal name | Description | MSA Notes |

Notes:1. TX Fault is not used and is always tied to ground through a 100 ohm resistor.2. TX Disable as described in the MSA is not applicable to the 1000BASE-T module, but is used for convenience as an input to reset the internal ASIC. This pin is pulled up within the module with a 4.7 KW resistor.Low (0 - 0.8 V): Transceiver onBetween (0.8 V and 2.0 V): UndefinedHigh (2.0 - 3.465 V): Transceiver in reset stateOpen: Transceiver in reset state3. Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7-10 KW resistor on the host board to a supply less than VCCT + 0.3 V or VCCR + 0.3 V.Mod Def 0 is tied to ground through a 100 ohm resistor to indicate that the module is present.Mod-Def 1 is clock line of two wire serial interface for optional serial IDMod-Def 2 is data line of two wire serial interface for optional serial ID4. LVTTL compatible with a maximum voltage of 2.5V. Not supported on HTSFP-24-111X5. RD-/+: These are the differential receiver outputs. They are ac coupled 100 ohm differential lines which should be terminated with 100 ohm differential at the user SerDes. The ac coupling is done inside the module and is thus not required on the host board. The voltage swing on these lines will be between 370 and 2000 mV differential (185 - 1000 mV single ended) when properly terminated. These levels are compatible with CML and LVPECL voltage swings.6. VCCR and VCCT are the receiver and transmitter power supplies. They are defined as 3.3 V ± 5% at the SFP connector pin. The maximum supply current is about 300mA and the associated in-rush current will typically be no more than 30 mA above steady state after 500 nanoseconds.7. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100 W differential termination inside the module. The ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 500 - 2400 mV (250 -1200 mV single ended), though it is recommended that values between 500 and 1200 mV differential (250 - 600 mV single ended) be used for best EMI performance. These levels are compatible with CML and LVPECL voltage swings.
