Texas Instruments Inc (TI), which develops analog ICs and embedded processors, has introduced its first transimpedance amplifier (TIA) for the 100G optical networking market.
TI says that, as a key component of the system, the ONET2804T brings high levels of sensitivity with negligible cross-talk penalty between channels and low input-referred noise (IRN < 2μA) to provide high signal integrity for stable and robust communication in hot-pluggable transceivers. The newest member of TI’s broad optical networking portfolio, the 100G TIA serves parallel optical interconnects in applications with data rates of up to 28Gbps, such as optical line-cards, point-to-point microwave backhauls and video over fiber.
The ONET2804T is available as a bare die with a 750μm channel pitch, enabling designers to wire bond directly to a photodiode (easing system integration and reducing system complexity). Also, using a two-wire I2C interface, designers can optimize their systems to drive high performance at low power consumption, aiding design flexibility says TI. Suggested retail pricing in 1000-unit quantities starts at $45.
Support is available on the High-Speed Interface Forum in the TI E2E Community, where engineers can search for solutions, get help, share knowledge and solve problems with fellow engineers and TI experts.
The firm says that the ONET2804T four-channel 28Gbps TIA adds a new dimension to its portfolio of optical networking products, which includes various types of laser drivers and limiting amplifiers for building optical networking systems.
