III. Low Speed Signals
RX_LOS and TX_DISABLE 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 Rev. 5.5
