Notes/Conditions
Table 2. Electrical power interface
Note 1:
Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz 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 VI, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2)
must be pulled up to host_Vcc. Note – MOD_DEF(0) is grounded inside the GBIC to
indicate the correct mode of operation.
For more detailed information, see sections 5.3.1 – 5.3.8 in the GBIC Specification Rev.
