FTR-1519-V2 Extended GBIC Product Specification – November 2007
II.
Finisar FTR-1519-V2 GBICs have an extended power supply voltage range of 3.15V to
5.5V as described in Table 2. They are compatible with both 5V and 3.3V systems. The
GBIC specification calls for a range of only 4.75V to 5.25 volts. The 6V maximum
voltage is not allowed for continuous operation, however, TX_FAULT and
TX_DISABLE circuitry in Finisar GBICs will function at 6V.
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.
