Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
* The device can withstand continuous exposure to the specified limits without damage.
Characteristics
1. Tested in a 50 Ω system with 27 Ω series matching resistor.
2. Eight-channel loading, 10% OMI, 40 km fiber.
3. Measured at 42 MHz.
4. Measured at 553.25 MHz, 577.25 MHz. and 595.25 MHz.
5. Consult an Agere Systems account manager for other wavelengths.
