Opnext Selects Mindspeed(R)'s 10 Gbps Limiting Amplifier for New Transceiver Designs; Mindspeed's M02140 Limiting Amplifier Provides Superior Performance at Lower Cost Than Gallium Arsenide (GaAs) Devices.

NEWPORT BEACH, Calif. -- Mindspeed Technologies Inc. (NASDAQ:MSPD), a leading supplier of semiconductor solutions for network infrastructure applications, today announced that Mindspeed's M02140 10 gigabit per second (Gbps) limiting amplifier has been selected by Opnext Inc., a global leader in high-performance optical components, for use in its TRV series of 300-pin transponders and its TRE series of Xenpak and X2 modules.

Mindspeed's latest physical media dependent (PMD) product for the growing 10 Gbps market is an integrated high-gain limiting amplifier that offers higher performance at lower cost than earlier GaAs devices. The M02140 amplifier features the size and power efficiency to enable low-cost hot-pluggable XFP, X2 and Xenpak modules, and supports data rates up to 12.5 Gbps for datacom and telecom optical links in enterprise and public networks.

"We are pleased with the outstanding performance of Mindspeed's M02140 limiting amplifier," said Satoshi Aoki, vice president of research and development for Opnext. "Mindspeed's solution helps our modules achieve excellent input sensitivity and jitter tolerance, a key element in offering leading-edge competitive module solutions and securing top-tier design wins."

"Our new fully integrated, low-power 10 Gbps limiting amplifier offers our customers a significant price and performance advantage, while facilitating the industry's migration to 10 Gbps," said Hasnain Bajwa, director of marketing for Mindspeed.

Technical Details

The M02140 is fully equipped with on-chip programmable features including output amplitude level and adjustable signal detect threshold setting. The device also includes a received signal strength indicator (RSSI) and a fully integrated DC-offset cancellation loop that requires no external components. Manufactured using an advanced silicon germanium (SiGe) bipolar complementary metal-oxide semiconductor (BiCMOS) process, the M02140 delivers significantly improved performance over earlier GaAs-based devices, when compared in terms of power, efficiency and noise reduction, at a lower cost.

Rated for operation up to 12.5 Gbps, the M02140 limiting amplifier consumes only 185 milliwatts at 3.3 volts (typical), with 5.5 millivolts (typical at 10.3 Gbps) of input sensitivity and 0.8 picoseconds (ps) root mean square (rms) random jitter. With typical output rise/fall times of 23/27 ps, the M02140 offers unparalleled performance over a wide, -40C to +85C industrial operating temperature range.

Mindspeed's fiber-optic portfolio spans the entire spectrum of optical networking transceiver solutions from OC-3 to OC-192 data rates, in support of synchronous optical network (SONET), synchronous digital hierarchy (SDH) and gigabit Ethernet/Fibre channel digital data transmission standards.
