4 / 10 page FTR-1629-XX DWDM GBIC Preliminary Product Specification – June 2003 F i n i s a r © Finisar Corporation PRELIMINARY and Confidential Page 4 Rev D, June 2003 II. Electrical Power Interface The GBIC specification calls for a range of 4.75V to 5.25 volts as described in Table 2. The maximum voltage of 6V is not to be applied continuously. 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 XI, “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 Revision 5.5 1. Parameter Symbol Min Typ Max Units Notes/Conditions Supply Current Is 250 400 mA Tc <= 70 oC 350 mA Tc <= 65 oC Inrush Current Isurge 30 mA <= 300 msec above steady state current Maximum Voltage Vmax 6 V Input Voltage Vcc 4.75 5.0 5.25 V Referenced to GND Table 2.
