Ensphere Solutions Announces the Availability of 12-port and 4-port 10G Laser Diode
Driver Arrays Targeting 10G, 40G, and 100G Long Haul Optical Modules
-- Most integrated and smallest driver arrays for FP/DFB lasers –
Santa Clara, Calif., June 14, 2010 – Ensphere Solutions, an emerging leader in advanced
communications semiconductor ICs, today announced the availability of two new 10G laser diode
driver arrays (LDDs). The 10G drivers provide a highly integrated solution for 10G, 40G, and
100G optical modules where they deliver high performance and low solution costs in four-port
(ESI-1014), and twelve-port (ESI-1110) applications.
ESI-1014 and ESI-1110 driver arrays are able to support a wide variety of laser RC time
constants, allowing them to drive FP/DFB lasers. They are capable of supplying up to 100 mA of
bias and 50 mA of modulation currents (per port). When used in a shunt configuration, they can
dramatically reduce a design’s overall power dissipation and PCB area by assuming the heavy
burden of driving low impedance laser diodes while presenting a 100Ω load to the preceding
driver. In addition, crosstalk between adjacent ports is less than -30 dB. Ensphere’s LDDs are
implemented in a low power CMOS technology and only consume 100 mW/port - including the
power dissipated by the laser.
Both laser driver ICs are available as raw dies, in either flip-chip or die-bonding configurations.
They are fully characterized over industrial temperature range.
“These products have been defined and developed in close cooperation with leading optical
module vendors” said Hessam Mohajeri, Ensphere’s Chief Executive Officer. “The single most
important differentiator for these products is the system performance they deliver while all
channels are running at full speed”.
“The die for these arrays can be mounted directly adjacent to the laser array within the optical
subassembly or module. This scheme minimizes the footprint and trace lengths improving the
performance and compactness of the module” said Al Gharakhanian, Ensphere’s VP of
Marketing. “Our application engineering team has accumulated a wealth of experience building
optical modules using these drivers”.
Availability
Sample quantities of the ESI-1014 and ESI-1110 driver arrays are available now. Production
quantities of both devices will be available at the end of August 2010. Contact Ensphere
Solutions for pricing.
