Notes/Conditions
Table 2. Electrical power interface
Note 1:
Receiver sensitivity is compliant with power supply sinusoidal of 20 Hz to 1.5Mhz up to specified
value applied through the recommended power supply filtering network
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 VIII, “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
