TI’s new 100G transimpedance amplifier drives high performance in optical networking systems

DALLAS (Sept. 22, 2014) – Texas Instruments (TI) (NASDAQ: TXN) today introduced its first transimpedance amplifier (TIA) for the 100G optical networking market. As a key component of the system, the ONET2804T brings high levels of sensitivity with negligible cross-talk penalty and low input-referred noise (IRN) to provide 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 28 Gbps, such as optical line cards, point-to-point microwave backhauls and video over fiber. For more information and to order samples, visit www.ti.com/onet2804t-pr.

Key features and benefits of the ONET2804T                                              

  • High level of sensitivity: Less than 2-uA IRN and virtually no cross talk between channels help achieve high signal integrity.
  • Design flexibility: Using a two-wire I2C interface, designers can optimize their systems to drive high performance at low power consumption.
  • Easy system integration: The new TIA’s 750-um channel pitch enables designers to wire bond directly to a photodiode, which reduces system complexity.

The ONET2804T four-channel 28-Gbps TIA adds a new dimension to TI’s popular line of optical networking products. In addition to TIAs, the portfolio features various types of laser drivers and limiting amplifiers to build optical networking systems.

Availability, packaging and pricing

The ONET2804T is available in a 750-um channel-pitch bare die. Suggested retail pricing in 1,000-unit quantities starts at US$45.00.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
