Inphi Corporation Extends 10 Gbps Transimpedance Amplifier Leadership with Two Flagship Products

Integrated TIA/LIAs hit the 100 milliwatt mark; poised to deliver superior performance, low cost, and low power across all network reaches

WESTLAKE VILLAGE, Calif., April 7, 2003  Extending its market leadership in receiver components for optical and broadband communications systems, Inphi Corporation today announced two new transimpedance/limiting amplifiers (TIA/LIAs). The Inphi® 1342TL and 1343TL provide unsurpassed performance and flexibility for a wide range of applications, including 10 Gbps Ethernet, SONET/SDH optical receiver modules, and broadband instrumentation. For the first time, receiver module manufacturers have access to integrated TIA/LIAs with power dissipation as low as 100 milliwatts (mW), thereby reducing bill of materials and manufacturing costs while meeting strict multisource agreement (MSA) power budgets. These OEMs previously relied on a separate LIA to amplify signals from a TIA, which consumed as much as 490 mW of power.

The fact that Inphi has achieved power dissipation as low as 100 milliwatts with their new TIAs represents a significant milestone in communications technology," said Dr. Nobuo Shiga, general manager of the Electron Device Department at Sumitomo Electric Industries in Yokohama, Japan. This development is an important step toward enabling module manufacturers to meet the stringent power requirements for SFP transceivers."

We asked the top five optical manufacturers what would significantly change the playing field for TIAs, and they cited lower power consumption as their primary requirement," said Ashok Dhawan, president and CEO of Inphi. At 100 milliwatts for an integrated TIA/LIA with more than 23 decibels of dynamic range, Inphi has more than hit the mark. The high gain, wide dynamic range, and improved sensitivity of the new Inphi TIA/LIAs, together with their low power consumption and cost, will deliver SONET performance at Ethernet cost to all network reaches."

Features and Benefits
The 1342TL and 1343TL support data rates up to 10.7 Gbps and consume 140 mW and 100 mW of power, respectively. Both exhibit high gain, excellent input sensitivity, and low input noise to maximize receiver quality. The 1342TL includes DC slice level adjust and receive signal strength indicator (RSSI) to simplify fiber alignment during package assembly. The exemplary performance of these TIAs is evidenced by the highly symmetric output eye of the 1342TL. Moreover, the 1342TL yielded a bit error rate of 10–12 after 80 km of single mode fiber, even with no dispersion compensation included in the link.

The 1342TL and 1343TL are available for immediate purchase in die form in sample quantities, with volume production beginning in the second quarter of 2003. Unit pricing for the 1342TL is $33 for production quantities of 10,000 units.
