Mindspeed Technologies burst-mode laser driver uses 20% less power than prior solution

Telecom Lead in America: Mindspeed Technologies, a
provider of semiconductor solutions for network infrastructure applications,
has launched the latest addition to its burst-made laser drivers for optical
networking units (ONUs).

The next-generation optical networking unit burst-mode
driver solution is designed to offer fiber-to-the-x (FTTx) multi-play services
via fiber-access networks using Gigabit Ethernet passive optical network
(GEPON) and Gigabit PON (GPON) technology.

The integrated solution features power-saving sleep and
current reduction modes and supports data rates to 3.1Gbps in a small 4×4 mm

“The M02099 family of burst-mode laser driver
chipsets builds on the feature set of our widely deployed M02090 and M02098
drivers, including lower power dual-closed-loop EyeMinder(TM) technology that
delivers real-time monitoring and compensation for laser aging and temperature
effects,” said Gary Shah, vice president of product marketing, high
performance analog (HPA) at Mindspeed.

The M02099 chipset family can be used in traditional
modules and is ideal for system designs that reduce bill-of-materials (BOM)
costs by mounting optical subassemblies directly on the ONU board.

Mindspeed will be demonstrating the M02099 chipset family
and its end-to-end GPON, GEPON, 10G-GPON/EPON solutions at The Optical Fiber
Communication Conference and Exposition and the National Fiber Optic Engineers
Conference (OFC/NFOEC 2012), March 6-8, 2012, at the Los Angeles Convention

Mindspeed’s M02099 family of chipsets features a
programmable burst-mode laser driver integrated with a continuous-mode limiting
amplifier. The M02100 driver includes on-chip electrically erasable
programmable read-only memory (EEPROM) for storing calibration constants and
performance settings, and can support more than one million write cycles.

In addition to operating without external control, the
devices also may operate under the control of an external microcontroller or
media access control (MAC) device. The M02099 chipset family delivers 3.1Gbps
data rates for both transmitter (Tx) and receiver (Rx) operations with isolated
power pins and independent shutdown.
