6. The specified transconductance is the ratio between the biasing current at pin BIAS and the voltage at pin TZERO,
7. The values indicate the guaranteed interval, i.e. the lowest attainable output current is always lower than 3 mA and
8. The voltage rise and fall times can be larger, due to capacitive effects. Specifications are guaranteed by design and
9. Measured in a frequency band from 250 kHz to 5 MHz, according to “ITU-T Recommendation G.813” .
10. The values indicate the guaranteed interval, i.e. the lowest output current always is less than 2.5 mA and the highest
11. The response time is defined as the delay between the onset of the ramp on pin ALS (at 10% of the HIGH-level) and
12. The reference currents can be set by using a resistor between V

The electrically generated (current) jitter is assumed to be less than 50% of the optical output jitter. The specification
is guaranteed by design.

the extinction of the bias current (at 10% of the original value).
see Section “Bias alarm for TZA3041AHL” for detailed information. The corresponding range of low-bias thresholds
is between 1.8 and 19.5 mA. The high-bias threshold range is from 9 to 97.5 mA.
