Description

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 mV_p−p.

The high input signal dynamic range ensures low jitter output signals even when overdriven with input signal swings as high as 1200 mV_p−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
