Notes:

1. The ICC value is held nearly constant to minimize unwanted electrical noise from being generated and conducted or emitted to

neighboring circuitry.

2. Power dissipation value is the power dissipated in the receiver itself. It is calculated as the sum of the products of VCC and ICC minus the sum

of the products of the output voltages and load currents.

3. These outputs are compatible with 10K, 10KH and 100K ECL and PECL inputs.

4. These are 20% - 80% values.

5. The Signal Detect output will change from logic “VOL” to “VOH” within 100 μs of a step transition in input optical power from no light to -26 dBm.

6. The Signal Detect output will change from logic “VOH” to “VOL” within 350 μs of a step transition in input optical power from -26 dBm to no light.
