Rev J, August 2004
II.
Electrical Power Interface
The GBIC specification calls for a range of 4.75V to 5.25 volts as described in Table 2.
The maximum voltage of 6V is not to be applied continuously.
III.
Low Speed Signals
RX_LOS, TX_DISABLE, and TX_FAULT are TTL signals as described in Table 3.
MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA) are open drain CMOS signals (see
section IX, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2)
must be pulled up to host_Vcc. For more detailed information, see sections 5.3.1 – 5.3.8
in the GBIC Specification Revision 5.5
