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. If host_Vcc is 3.3V, then they must be pulled to 3.3V.
If
host_Vcc is 3.3V, do not pull the MOD_DEF pins to 5V.
For more detailed information,
see sections 5.3.1 – 5.3.8 in the GBIC Specification Rev. 5.4
