The ONET4291PA is a versatile, high-speed, rate-selectable limiting amplifier for multiple fiber-optic applications with data rates up to 4.25 Gbps
The ONET4291PA is a versatile, high-speed, rate-selectable limiting amplifier designed for multiple fiber-optic applications with data rates up to 4.25 Gbps. It features a two-wire digital interface that allows for the selection of bandwidth, output amplitude, and loss-of-signal (LOS) thresholds. The device provides a gain of about 43 dB and ensures a fully differential output swing for input signals as low as 5 mV.
| Data Rate | 1 Gbps to 4.25 Gbps |
|---|---|
| Supply Voltage | 3.3 V |
| Operating Temperature | -40°C to 85°C |
| Gain | about 43 dB |
