FTR-8519-3D GBIC Product Specification – November 2007
Finisar
Finisar Corporation November 16, 2007 Rev. E3
Page 3
Finisar FTR-8519-3D GBICs have an extended power supply voltage range of 3.15 V to
5.5 V as described in Table 2. They are compatible with both 3.3V and 5 V systems.

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 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.
