Mindspeed Adds New Generation of Transimpedance Amplifiers (TIAs) to Growing Physical Media Device (PMD) Offering for Passive Optical Network (PON) Equipment

NEWPORT BEACH, Calif.--(BUSINESS WIRE)--Mindspeed Technologies, Inc. (NASDAQ:MSPD), a leading supplier of semiconductor solutions for network infrastructure applications, today announced the company’s latest generation of high-sensitivity 1.25Gbps and 2.5Gbps TIAs. The M02025 and M02028 TIAs improve optical sensitivity and dynamic range while adding key new features that reduce the cost of optical network terminals (ONTs) for deploying fiber-to-the-x (FTTx) multi-play services over fiber-access networks that use Gigabit Ethernet passive optical network (GEPON) and Gigabit PON (GPON) technology.

“Mindspeed continues to expand our PMD product offering in the PON market”

Mindspeed will be demonstrating its TIAs and the rest of its broad family of PMD solutions at the China International Optoelectronic Exposition (CIOE), September 6-9, 2010, in booth 209/210 at the Shenzhen Exhibition and Convention Center in Shenzhen, China. Mindspeed®’s M02025 and M02028 devices extend the capabilities of the company’s widely deployed GPON and GEPON TIAs, which are shipping in high volumes to Tier One customers worldwide. The M02025 and M02028 devices also can be used with the company’s M02098 highly integrated laser drivers and post amplifier with dual closed-loop Eye-Minder™ technology. The combination creates a complete PON module chipset solution that delivers superior design margin, while lowering the overall module manufacturing cost.

“Mindspeed continues to expand our PMD product offering in the PON market,” said Hasnain Bajwa, senior vice president and general manager of Mindspeed’s lightspeed connectivity solutions (LCS) business unit. “The M02025 and M02028 TIAs offer superior sensitivity and, when used with our highly integrated laser drivers, streamline the design of GPON and GEPON ONTs.”

LuxNet Corporation has collaborated with Mindspeed to provide the Bi-directional Optical Sub-Assembly (BOSA), using the M02025 on a GPON Small-Form-Factor (SFF) reference design to be showcased at CIOE.

"LuxNet has a long history working with Mindspeed for designs spanning several generations of TIA devices," said Leslie Huang, vice president of worldwide sales. "We are particularly pleased with the M02025 device’s ability to provide additional performance margin and cut overall system costs for GPON and OC-48 modules."

Product Details

The 1.25Gbps M02028 TIA and 2.5Gbps M02025 TIA both feature wide input dynamic range and support different transmission distance requirements, including short-haul fiber-optic systems that require typical input overload of 4 mA (peak to peak). The devices are also well suited for high-split-ratio PON networks that require TIAs capable of detecting very small signals in a noisy environment. Typical sensitivity for the M02025 TIA in Receiver Optical Sub Assembly (ROSA) applications is better than -28dBm at 3Gbps and better than -30dBm at 2.5Gbps when used with a PIN diode, and performance with an Avalanche Photodiode (APD) exceeds -35dBm at 2.5Gbps. Typical sensitivity for the M02028 TIA is better than -31dBm at 1.25Gbps when used with a PIN diode.

The Mindspeed TIAs each support multiple data rates, from 1.25Gbps to 3Gbps and from 100Mbps to 1.25Gbps for the M02025 and M02028, respectively. Each TIA also reduces overall ROSA assembly costs by eliminating the need for photodiode filtering caps and internal ROSA power supply decoupling caps. Both devices are designed with integrated average photodiode current outputs that support both PIN and APD-based photodiode monitoring with excellent accuracy. The M02025 and M02028 also feature an on-die temperature sensor that can be used for APD temperature monitoring implementations.
