1-Gbps to 4.25-Gbps limiting amplifier with LOS & RSSI

The 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 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 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 typically dissipates less than 89 mW and it is characterized for operation from -40°C to 85°C.
