Semtech Introduces Combination Laser Driver and Limiting Amplifier Platform for 10G PON Applications

2016-09-06 | Return

Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the release of the GN28L95 integrated laser driver and limiting amplifier for asymmetric 10 gigabit PON applications, combining for the first time Semtech’s unique automatic laser calibration technology with programmable 2.5 gigabit transmit and 10 gigabit receive signal paths. The 10G PON market is expected to benefit from the ongoing roll-out of fiber-to-the-home (FTTH) network deployments where PON delivers economical Internet connectivity. Semtech is showcasing its optical products at the China International Optoelectronic Expo (CIOE) in Shenzhen, booth 1C01, on September 6-9.

This technology helps achieve cost reduction in the optical networking unit (ONU) in fiber-to-the-home customer premises equipment by enabling optics to be mounted directly on the main ONU board. This helps manufacturers keep pace with the rapid global growth and cost competition in the market for next-generation high data rate XGPON and 10GEPON ONUs.

The GN28L95 is available in a small 4x4 millimeter QFN package, and it is compatible with a wide range of low-cost optics and requires minimal setup time with high production yield. Low-cost lasers and avalanche photodiodes (APDs) can be optimized using unique eye shaping technology to both transmit and receive. Further cost savings can be expected to be achieved through integration of the APD controller and digital control directly with the MAC processor.

To optimize layout and minimize cost, the part is available in a small 4x4 millimeter QFN package. The GN28L95 product announcement coincides with the China International Optoelectronic Expo (CIOE) in Shenzhen September 6-9 where Semtech is demonstrating its optical products in booth 1C01.

Key Features of the GN28L95

>Patented and proven automatic laser calibration is compatible with a wide range of industry lasers

>Programmable 2.5G Tx with eye-shaping to optimize laser performance

>Programmable 10G Rx with equalization and pre-emphasis to optimize APD performance
