5/9/2018, MACOM today announced the MAOM-006408, a single-chip, four-channel linear differential modulator driver for 64 GBaud long-range, metro and data center interconnect (DCI) applications with up to 64 QAM High-order modulation scheme.
The device achieves low power consumption, high bandwidth and excellent linearity with a very small chip size, and is expected to meet the HB-CDM and IC-TROSA standards being developed by the Optical Internet Forum (OIF).
As telecom operators and Internet content providers continue to drive increased demand for data rates and panel densities, OIF is working to develop standards for small form factors for 64 Gbaud and 64 QAM. In order to meet the small size and high operating frequency requirements, package-level integration of the driver chip and the Mach-Zehnder modulator becomes an advantage. This drives the need to implement a four-channel linear driver in a single semiconductor die compared to existing discrete driver solutions where multiple dies are integrated in a surface mount module.
Rajiv Somisetty, senior product manager for MACOM Networks, said: "We are very excited to introduce this new highly integrated high bandwidth modulator driver. Over the past seven years, MACOM has been at the forefront of innovation in modulator drive coherent technology deployment. With the latest portfolio of modulator drivers for 64 Gbaud systems, our leading position will be extended to next-generation 400G and above deployments."
MACOM's MAOM-006408 integrates four channels in a single silicon germanium chip and enables full digital control via the Serial Peripheral Interface (SPI), driving the advancement of technological innovation standards. The MAOM-006408 has been optimized to flexibly drive a wide range of MZ modulators with very low power consumption. In addition, it offers full analog and full digital control and is expected to meet the requirements of the HB-CDM and IC-TROSA standards.
