Opnext 40G DQPSK Optical Module Moves Into Mass Production
Both ICs feature power management and boast the best available accuracy. Outstanding driver accuracy of +/-0.5% guarantees exact brightness and color matching and channel-to-channel current matching is +/-0.2%, resulting in high lighting contrast ratios for the best possible picture quality and 3D effects. In addition, the high precision AS3695A and AS3695C include novel power feedback regulation for controlling external power supplies for the highest system efficiency and reduced power in LED backlit LCD TVs.
“austriamicrosystems is well known for producing the best ICs for driving LED backlighting systems,” stated Markus Luidolt Marketing Manager Panel Lighting at austriamicrosystems. “Because of their outstanding performance, our drivers have been designed into many top TV brands all over the world. This early market dominance has helped us to better understand direct and edge type TVs and has resulted in this next generation of LED drivers.”
The devices are programmable via a SPI (serial peripheral interface) port and provide built-in safety features, including thermal shutdown and open and short LED detection. Other features include linear current setting using a 10-bit DAC, output slew rate programmability, H-Sync and V-Sync inputs to synchronize with a TV, direct PWM mode, undervoltage auto-turnoff, overvoltage auto-turnoff, temperature shutdown and fault interrupt output.
Samples are available now. The 1,000 piece price for the AS3695A QFN is $2.10. The AS3695C QFN and AS3695C LQFP are $2.20 and $2.70, respectively.

The 40G DQPSK market represents one of the fastest growing segments in optical communications.
Opnext, a global leader in the design and manufacturing of optical modules and components, has unveiled its 40Gbps differential quadrature phase-shift keying (DQPSK) module has moved to full production and is now shipping in volume.
The demand for 40G interfaces continues to grow due to the continued increases in IP and video networks driving the upgrades of regional, long-haul and submarine networks.
In its most recent report regarding 40G components, Ovum forecasted that the 40G DWDM market for DQPSK modules would grow at a compound annual growth rate (CAGR) of 16 % from US$175 million in 2010 to more than US$360 million in 2015.
According to Ovum, 40G DQPSK is one of the fastest growing segments in optical communications. It is being deployed within metropolitan networks to economically address the bandwidth bottlenecks caused by the exponential growth in enterprise and consumer traffic generated by the increased usage of smartphones and video.
As a leading manufacturer of 40Gbps optical modules, Opnext, through its DQPSK technology, offers improved optical signal-to-noise ratio (OSNR) characteristics and 50 GHz channel spacing which optimizes performance. By implementing a DQPSK solution, optical signals are less affected by chromatic dispersion (CD), polarization mode dispersion (PMD), and optical bandwidth limitations after travelling through multiple ROADM nodes. A system designer using an Opnext DQPSK solution can install the module in a network path that is
