MACOM Announces the Industry’s Most Integrated Laser Driver for 28G SFP28 Optical Modules at OFC 2017

  • Ideal for next generation 5G wireless, enterprise and storage network applications
  • Laser Driver minimizes power consumption, reduces need for external components and provides customers with design flexibility
  • Chipset to be showcased at MACOM’s booth #1736 at OFC 2017
Lowell, Mass, MACOM Technology Solutions Inc. (“MACOM”), today announced the MALD-37030 and MALD-37031, the industry’s most integrated laser driver solutions.
With the growing demand for data, wireless, enterprise and data center OEMs are continually looking for ways to drive lower power, smaller size and lower costs. MACOM’s integrated laser driver minimizes power consumption and reduces need for external components, providing customers with design flexibility and board space savings ideal for SFP28 Long-Reach (LR) optical module designs in next generation 5G wireless, enterprise and storage networks applications.
These devices have an integrated direct modulated laser (DML) driver, limiting amplifier, dual CDRs, power management functionality, and digital diagnostics monitoring. Specifically designed for SFP28 optical modules, the MALD-37030 is intended for wireless 24G CPRI and 25G Ethernet data communication applications, while the MALD-37031 is ideally suited for 28Gbps Fiber Channel Storage Networks.
“The new laser drivers offer the industry’s most integrated features and functionalities for small form factor optical module designs,” said Angus Lai, Director, High-Performance Analog Product Marketing, at MACOM. “Sampling today, these highly integrated devices minimize power consumption and external components, providing design flexibility that enables our customers to develop the best in class SFP28 optical module solutions.”
The transmit channel includes a CTLE with adaptive/programmable equalization and a flexible output driver to directly drive DML lasers in TO-Cans or in hybrid packages. An internal buck-boost converter tracks the laser forward voltage and automatically generates laser anode voltages to optimize power dissipation and maintain eye quality. The integrated DML driver offer the industry’s first 28G Dual Closed Loop (DCL) operation. This operating mode only requires calibration at room temperature then the extinction ratio (ER) and average optical power are automatically controlled across operating temperatures.
The receive channel includes a high-sensitivity limiting amplifier with programmable slice level adjustment and an output driver with programmable output swing. The CDRs in the transmit and receive channels are reference-free and can be programmed to support half rate as well as bypassed to support legacy or non-standard data rates. The devices have Integrated PRBS Generator and Checker and bidirectional loop back for system diagnostics
Paired with the MACOM best-in-class low power single channel TIA, M03002, and high-performance 131D-25G-LT5TC 25G DFB laser in TO-56 package, MACOM provides the most integrated and high-performance SFP28 LR chipset solution available today.
The MALD-37030/31 products are available in a cost effective 5x6mm LGA (Land Grid Array) package and support industrial temperature operation. A demonstration of MACOM’s SFP28 LR chipset will be on display by appointment at OFC in MACOM’s booth, #1736, March 21st-23rd in Los Angeles, CA. The demonstration includes MACOM’s 28Gbps DML driver, TIA packaged in ROSA and DFB laser packaged in TOSA for a complete chipset solutions.
