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. Parameter Supply Current Maximum Voltage Symbol Is Vmax Min Surge Current Isurge Input Voltage Vcc 4.75 Power Supply Rejection PSR 100 Typ 280 5.00 Max 350 6 Units mA V 400 mA 5.25 V mV Notes/Conditions Referenced to GND See Note 1. Peak to Peak Table 2. Electrical power interface Note 1: Receiver sensitivity is compliant with power supply sinusoidal of 20 Hz to 1.5Mhz up to specified value applied through the recommended power supply filtering network 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 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 Revision 5.53.
