1) : The falling edge of CKI+ clock input signal is at the DI+ data eye pattern crossing point.
2) : When open (or low) the module operates in Clocked-mode. When high the module operates in Non-clocked-mode.
3) : When open (or low) the module is in the operating mode. When high the module is in the shut down mode (no optical output power).
4) : TEC_GND must be connected with GND.
5) : When provided a digital alarm indicates that the laser is degraded. The active level is a low level.
6) : Alarm indicating when the laser temperature exceeds the threshold level. The active level is a high level.
7) : BACK(+), LDA and TDA pin cannot drive capacitive load. Acceptable capacitance is less than 50pF.
8) : When open (or low) the module outputs wavelength 1. When high the module outputs wavelength 2. (See wavelength table.)
