Notes:
1. This is the maximum voltage that can be applied across the Differential Transmitter Data Inputs to prevent damage to the input ESD protec-
tion circuit.
2. The outputs are terminated with 50 W connected to V_CC – 2 V.
3. The power supply current needed to operate the transmitter is provided to differential ECL circuitry.This circuitry maintains a nearly constant
current flow from the power supply. Constant current operation helps to prevent unwanted electrical noise from being generated and
conducted or emitted to neighboring circuitry.
4. This value is measured with the outputs terminated into 50 W connected toV_CC – 2 V and an Input Optical Power level of –14 dBm average.
5a. The power dissipation of the transmitter is calculated as the sum of the products of supply voltage and current.
5b. The power dissipation of the receiver iscalculated as the sum of the products of supply voltage and currents, minus the sum of the products
of the output voltages and currents.
6. This value is measured with respect to V_CC with the output terminated into 50W connected to V_CC - 2 V.
7. The data output rise and fall times are measured between 20% and 80% levels with the output connected to V_CC – 2 V through 50 W.
8. These optical power values are measured
with the following conditions:
The Beginning of life (BOL) to the End of Life (EOL) optical power degradation is typically 1.5 dB per the industry convention for long wave-
length LEDs.The actual degradation observed in Avago’s 1300 nm LED products is < 1 dB, as specified in this data sheet.Over the specified
operating voltage and temperature ranges.With 25 MBd (12.5 MHz square-wave), input signal. At the end of one meter of noted optical fiber
with cladding modes removed. The average power value can be converted to a peak power value by adding 3 dB. Higher output optical
power transmitters are available on special request. Please consult with your local Avago sales representative for further details.
