... Philips Semiconductors SDH/SONET STM1/OC3 laser drivers Bias alarm for TZA3031AHL The bias current alarm circuit detects whenever the bias current is outside a predefined range, and generates a flag. This feature can detect excessive bias current due to laser ageing or laser malfunctioning. The current applied to pin ALARMHI should be the maximum permitted bias current value attenuated by a ratio of 1:1500 ...
