The ONET4251PA is a versatile high-speed limiting amplifier for copper cable and fiber optic applications with
data rates up to 4.25 Gbps.
This device provides a gain of about 50 dB, which ensures a full 800-mVp-p differential output swing over its wide
input signal dynamic range.
The high input signal dynamic range ensures low jitter output signals even when overdriven with input signal
swings as high as 1200 mVp-p. …
