The ONET2501PA is a versatile high-speed limiting amplifier for multiple fiber optic applications with data rates
up to 2.5 Gbps.
This device 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 ONET2501PA is available in a small footprint 3 mm × 3 mm, 16-pin QFN package. The circuit requires a
single 3.3-V supply.
This power efficient limiting amplifier is characterized for operation from –40°C to 85°C
