Electrical Power Interface
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. 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.
