AK2572 Détails du produit

OUTLINES
The AK2572 enables to keep the optical power of the direct modulation LD (Laser Diode) constant by the APC (Automatic Power Control) circuit. It consists of a current programming function (APC_FF) responding to the temperature characteristics of each LD, and a Digital feedback function (APC_FB) to adjust the LD current based on the monitoring PD(Photo Diode) current.

FEATURES
■ Temperature compensation programming function (APC_FF) of Bias current (0~85mA) and Modulation current (0~10mA/0~2.2V) responding to the detected temperature by the On-chip temperature sensor.
■ Stable feedback function in the digital scheme (APC_FB).
■ SFP support TXFAULT function and 1k bit ID field (EEPROM UserArea).
■ LD Power leveling function by either Hardware pin control orRegister setting.
■ Various alarm functions of Optical output decline (OPTALM), Excessive LD current (CURRALM), Exceptional temperature (TEMPALM) and Irregular external signals(EXTALM1 and EXTALM2).
■ Operation adjustment function via 2-wire Digital interface after assembled into sub-system.
■ On-chipOscillator allows aSelf-runningoperation.
■ Single3.3 V[Typ.]powersupply.

APPLICATIONS
    For LD modules applied to Continuous and Burst mode
