3 / 9 page FTR-1621-XX WDM GBIC Product Specification - March 2002 F i n i s a r © Finisar Corporation 01-Mar-02 Rev.F Page 3 II. Electrical Power Interface Finisar FTR-1621-XX WDM GBIC modules have a power supply voltage range of 4.75V to 5.25V as described in Table 2. 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. Note – MOD_DEF(0) is grounded inside the GBIC to indicate the correct mode of operation. For more detailed information, see sections 5.3.1 – 5.3.8 in the GBIC Specification Rev. 5.41. Electrical Power Interface Parameter Symbol Min Typ Max Units Notes/Conditions Supply Current Is 280 350 mA Maximum Voltage Vmax 6 V Surge Current Isurge 400 mA Input Voltage Vcc 4.75 5.00 5.25 V Referenced to GND Power Supply Rejection PSR 100 mV 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 Low Speed Signals, Electronic Characteristics Parameter Symbol Min Max Units Notes/Conditions GBIC Output LOW VOL 0 0.5 V 4.7k to 10k pull-up to host_Vcc, measured at host side of connector GBIC Output HIGH VOH host_Vcc - 0.5 host_Vcc + 0.3 V 4.7k to 10k pull-up to host_Vcc, measured at host side of connector GBIC Input LOW VIL 0 0.8 V 4.7k to 10k pull-up to Vcc, measured at GBIC side of connector GBIC Input HIGH VIH 2 Vcc + 0.3 V 4.7k to 10k pull-up to Vcc, measured at GBIC side of connector Table 3.
