Product Summary

The ONET8501PBRGTT is a high-speed, 3.3-V limiting amplifier for multiple fiber optic and copper cable applications with data rates from 2 Gbps up to 11.3 Gbps. The device provides a two-wire serial interface which allows digital control of the bandwidth, output amplitude, output pre-emphasis, input threshold voltage (slice level) and the loss of signal assert level. Predetermined settings for bandwidth and LOS assert levels can also be selected with external rate selection pins. The applications of the ONET8501PBRGTT are (1)10-Gigabit Ethernet Optical Receivers; (2)2×/4×/8× and 10× Fiber Channel Optical Receivers; (3)SONET OC-192/SDH-64 Optical Receivers; (4)SFP+ and XFP Transceiver Modules; (5)XENPAK, XPAK, X2 and 300-pin MSA Transponder Modules; (6)Cable Driver and Receiver.
