DESCRIPTION
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 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 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.
