precautions (a) power supply: transient electric spike may cause a damage to the laser, the photodiode or ic chips. a surge-free power supply and a slow starter circuit should be used. to avoid causing an electrical surge, pins should not be connected or disconnected on the test fixture before turning power off . (b) the product should be grounded for obtaining the performance. (c) safety: the laser emits invisible light harmful to the human eyes. direct viewing should be avoided. input controls truth tables output alarms truth tables rxratesel (pin # k3) 0 1 or nc fec rate of 10.664gb/s and 10.709gb/s selected normal sonet rate of 9.953gb/s or ethernet rate of 10.3gb/s selected txratesel (pin # k21) 0 1 or nc fec rate of 10.664gb/s and 10.709gb/s selected normal sonet rate of 9.953gb/s or ethernet rate of 10.3gb/s selected rxreset (pin # k6) 0 1 or nc asynchronous demux system reset normal operation txreset (pin # k24) 0 1 or nc asynchronous mux system reset normal operation lsenable (pin # f21) 0 or nc 1 normal operation laser disable lsbiasalm (pin # f24) 0 1 laser bias alarm active normal operation lstempalm (pin # f27) 0 1 laser temperature alarm active normal operation rxlockerr (pin # b15) 0 1 indicates loss of pll lock normal operation txlockerr (pin # b30) 0 1 indicates loss of pll lock normal operation txphsadj1 (pin # d27) 0 or nc 0 or nc 1 1 txphsadj0 (pin # d24) 0 or nc 1 0 or nc 1 adjusts the phase of the txpclk by 0deg adjusts the phase of the txpclk by 90deg adjusts the phase of the txpclk by 180deg adjusts the phase of the txpclk by 270deg rxrefsel (pin # f15) 0 1 or nc selects an rxrefclk frequency of 155mhz selects an rxrefclk frequency of 622mhz rxmclksel (pin # b12) 0 1 or nc selects an rxmclk frequency of 155mhz selects an rxmclk frequency of 622mhz txrefsel (pin # f30) 0 1 or nc selects a txrefclk frequency of 155mhz selects a txrefclk frequency of 622mhz 3697c-0103 pc-d5
