MACOM announces CDR+VCSEL driver interoperability with II-VI VCSELs

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) says that its new MALD-37045 four-channel 25.78G/28.05G VCSEL driver – which features an integrated clock data recovery (CDR) and an equalizer – has been proven to be interoperable with vertical-cavity surface-emitting lasers (VCSELs) of II-VI Inc of Saxonburg, PA, USA.

Together with the MATA-37044, a companion transimpedance and limiting amplifier with CDR, MACOM's latest chipset solution has been implemented by customers in 100Gbps QSFP modules and active optical cables (AOCs) as a complete electronics solution with proven results, says the firm. The devices consume ultra-low power, making them suitable for small form-factor applications.

The MALD-37045 and MATA-37044 both feature CDR functionality for use as a complete transmit and receive solution for optical modules and on-board optical engines. The reference-free CDRs in the MALD-37045 and MATA-37044 are programmable, re-timing at 25.78, 27.95 and 28.05Gbps.The companion devices have their respective outputs and inputs spaced on 250µm centers to maintain compatibility with standard optical interfaces, and each device can be individually controlled through the 2-wire serial interface.

The MALD-37045 provides programmable bias and modulation current, enabling interoperability with a variety of VCSELs, including II-VI's lasers. The MATA-37044 includes a high-sensitivity transimpedance amplifier (TIA) with selectable bandwidth to support interoperability with short-wave and long-wave photodetectors.

"Our new chipset expands MACOM's existing family of CDRs, laser drives and TIA products and, by combining our expertise in low-power and high-performance semiconductors with II-VI's established 25.8Gbps VSCELs, we are working to ensure that our customers get a fully interoperable, best-in-class solution," says MACOM's director of marketing Marek Tlalka. 

"As a result of this synergy, we are able to provide customers with a reliable, low-power and proven solution," comments Michele Agresti, II-VI's product line manager for datacom VCSELs. 

MACOM says that the MALD-37045 and MATA-37044 are optimal one-stop solutions for optical modules, active optical cables and on-board optical engines. They can be used in 100G Ethernet, EDR InfiniBand and 32G Fibre Channel applications, providing a low-power interoperable solution required by small form-factor optical subassemblies.

The MALD-37045 and MATA-37044 is being shown operating with II-VI VCSELs in private demonstrations in booth #1B83 at the 17th China International Optoelectronic Expo (CIOE 2015) in Shenzhen, China (31 August – 3 September).
