GigOptix samples single and quad channel 28-Gbps limiting DML drivers

Nov. 25, 2015
GigOptix, Inc. (NYSE MKT: GIG) has announced sampling of a pair of 28-Gbps limiting directly modulated laser (DML) drivers for 25-Gbps and 100-Gbps Ethernet and 32GFC and 128GFC Fibre Channel optical transmission applications, particularly data center and cloud computing. The DML drivers include the single-channel HXT42100 and the quad-channel HXT42400.

GigOptix, Inc. (NYSE MKT: GIG) has announced sampling of a pair of 28-Gbps limiting directly modulated laser (DML) drivers for 25-Gbps and 100-Gbps Ethernet and 32GFC and 128GFC Fibre Channel optical transmission applications, particularly data center and cloud computing. The DML drivers include the single-channel HXT42100 and the quad-channel HXT42400.

The HXT42100 single-channel driver is small enough to be part of a TO-can transmit optical subassembly (TOSA), GigOptix says. Both drivers support voltage supply as low as 2.5 V with respective modulation and bias currents of 50 mA and 50 mA. For higher modulation and bias current requirements, the chips can be driven with supply voltages up to 3.3 V. A single channel operating at 2.5 V will dissipate less than 200 mW, according to the company. Neither device requires an external digital to analog converter (DAC), GigOptix adds.

Both the HXT42100 and HXT42400 include modulation, bias, and pulse shaping DAC, with an integrated I2C interface for control, monitoring, fault, and status detection. The 1-MHz I2C interface enables control of such functions as signal detect and squelch, bandwidth adjust, mask-able fault and interrupt generation, internal temperature monitor selection, channel polarity inversion, and programmable CTLE input equalization.

The HXT42100 and HXT42400 should be ready for production in the second quarter of calendar 2016.
