MARCH 19, 2009 -- Oki Semiconductor Co., Ltd. (search Lightwave for Oki Semiconductor) has introduced a pair of single-chip EML line drivers, one for 40-Gbps applications and the other for 100-Gigabit Ethernet use.
The KGA8205 is a single-chip EML driver IC (see above) that can be mounted on a 40-Gbps EML based on the XLMD multisource agreement (MSA). The KGA8205 features small size (1.8x1.2 mm) and a power consumption of 1.1 W (amplitude 2.3 Vpp). Samples of the device are available now and volume shipment is scheduled to start from June 2009.
The KGA8205 is provided in die form, allowing direct EML connection without the need to add external output bias circuit components.
At 100 Gbps, the KGA8105 single-chip EML driver (see below) is sampling now and volume shipment is scheduled to start from June 2009. The KGA8105 operates at 25 Gbps and uses Oki Semiconductor's GaAs PHEMT process to offer high speed and low power consumption performance of 1.25 W (2.5 Vpp output amplitude) at 25.8 Gbps operation. The product is presently provided in die form, with plans for release in small package form, 4x4 mm QFN, in the second quarter of this year.
