DESCRIPTION  
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  
.
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.  
BLOCK DIAGRAM  
A simplified block diagram of the ONET4251PA is shown in Figure 1.  
This compact 3.3 V, low power 4.25 Gbps limiting amplifier consists of a high-speed data path with offset  
cancellation block, a loss of signal and RSSI detection block, and a bandgap voltage reference and bias current  
generation block.
