ONET4251PA中文资料具有 LOS 和 RSSI 的 1Gbps 至 4.25Gbps 限幅放大器数据手册TI规格书

描述 Description

The ONET4251PA is a versatile high-speed 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 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.
The ONET4251PA comprises 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. It requires a single 3.3-V supply.
This power efficient limiting amplifier dissipates less than 89 mW typical. It is characterized for operation from -40°C to 85°C.
