1000BASE-T Copper GBIC Transceiver SPT-GE-T1

Features:
- Hot-pluggable GBIC footprint
- Extended case temperature range (0°C to +70°C )
- fully metallic enclosure for low EMI
- Low power dissipation (1.05 W typical)
- Compact RJ-45 connector assembly
- Access to physical layer IC via 2-wire serial bus
- 1000 BASE-T operation in host systems with SERDES interface
Applications:
- 1.25 Gigabit Ethernet over Cat 5 cable
Description:
SPT-GE-T1 1000BASE-T Copper GBIC transceivers are based on the GBIC Multi Source Agreement (MSA). They are compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE Std 802.32. The 1000BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features. The SPT-GE-T1 uses the GBIC’s RX_LOS pin for link indication, and 1000BASE-X auto-negotiation should be disabled on the host system. The SPT-GE-T1 is compatible with 1000BASE-X auto-negotiation, but does not have a link indication feature (RX_LOS is internally grounded).
+5V Volt Electrical Power Interface
The SPT-GE-T1 has an input voltage range of +5V +/- 5%. The 5.5V maximum voltage is not allowed for continuous operation.

Low-Speed Signals
MOD_DEF (1) (SCL) and MOD_DEF (2) (SDA), are open drain CMOS signals (see section VII, “Serial
Communication Protocol”). Both MOD_DEF (1) and MOD_DEF (2) must be pulled up to host_Vcc.

Notes:
1. Clock tolerance is +/- 50 ppm
2. By default, the SPT-GE-T1 is a full duplex device in preferred master mode
3. Automatic crossover detection is enabled. External crossover cable is not required
4. 1000 BASE-T operation requires the host system to have an SGMII interface with no clocks, and the module PHY to be configured per Application Note AN-2036. With a SERDES that does not support SGMII, the module will operate at 1000BASE-T only.
