(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

DescriptionThe ONET4201PA is a versatile high-speed, 3.3-V limiting amplifier for multiple fiber optic applications with data rates up to 4.25 Gbps.
This device ONET4201PA provides a gain of about 50 dB, which ensures a fully differential output swing for input signals as low as 3 mVp-p.
The high input signal dynamic range ensures low jitter output signals even when overdriven with input signal swings as high as 1200 mVp-p.
The ONET4201PA provides a loss of signal detection as well as a received signal strength indicator.
The ONET4201PA part is available in a small footprint 3-mm*3-mm 16-pin QFN package and is pin-compatible with the ONET2501PA and ONET3301PA.
This power efficient limiting amplifier ONET4201PA typically dissipates less than 89 mW and it is characterized for operation from 40°C to 85°C.
