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.
The ONET4201PA is a versatile high-speed limiting amplifier designed for multiple fiber optic applications, including SONET/SDH transmission systems and Gigabit Ethernet receivers. It operates at data rates up to 4.25 Gbps and provides a gain of approximately 50 dB to ensure fully differential output swings even for low input signals as small as 3 mV.
The device features loss of signal (LOS) detection and a receive signal strength indicator (RSSI). It is supplied by a single 3.3-V voltage and is available in a compact 3-mm x 3-mm 16-pin QFN package. The part is pin-compatible with the ONET2501PA and ONET3301PA models.
