PIN Descriptions:
Notes:
- Circuit ground is connected to chassis ground
- Should be pulled up with 4.7k – 10k Ohms on host board to a voltage between 2.0 V and 3.6 V. MOD_DEF (0) pulls line low to indicate module is plugged in.
- LVTTL compatible with a maximum voltage of 2.5V.
General Specifications
Notes:
- Clock tolerance is +/- 50 ppm
- By default, the GAO-CUSFP-103 is a full duplex device in preferred master mode
- Automatic crossover detection is enabled. External crossover cable is not required.
- GAO-CUSFP-104 does not support SGMII .With a SERDES the module will operate at 1000BASE-T only.
3.3 Electrical Power Interface:
The GAO-CUSFP-104 has an input voltage range of 3.3 V +/- 5%. The 4V maximum voltage is not allowed for continuous operation.
Note (1): Power consumption and surge current are higher than the specified values in the SFP MSA.
Low Speed Signals
MOD_DEF (1) (SCL) and MOD_DEF (2) (SDA) are open drain CMOS signals (see “Serial Communication Protocol”). Both MOD_DEF (1) and MOD_DEF (2) must be pulled up to host_Vcc.
Serial Communication Protocol
GAO-CUSFP-104 supports the 2-wire serial communication protocol outlined in the SFP MSA. It uses an Atmel AT24C02B 256 byte EEPROM with an address of A0h.
High Speed Electrical Interface
All high-speed signals are AC-coupled internally.
