MACOM launches dual-channel 96Gbaud TIA and quad-channel modulator driver for 600 and 800Gbps optical networking

MACOM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) has announced the availability of its new dual-channel 96GBaud transimpedance amplifier (TIA) and quad-channel modulator driver for coherent optical networking applications.

Increased demand for data capacity in metro and data-center interconnect (DCI) applications is being driven by trends like the Internet of Things (IoT), autonomous vehicles (AVs), virtual reality (VR) and artificial intelligence (AI). As market demand moves to higher data rates for lower overall cost-per-bit, coherent optical systems are operating at higher symbol rates and with more complex modulation schemes to support data rates of 800Gbps and higher on a single wavelength.

This move to higher data rates drives the need for modulator drivers and TIAs with ever increasing levels of performance. MACOM says that its new MATA-009806 dual-channel TIA and MAOM-009408 quad-channel driver offer the high bandwidth, low noise and low power consumption to enable integrated coherent receivers (ICRs), high-bandwidth coherent driver modulators (HB-CDMs) and integrated coherent transmit-receive optical sub-assemblies (ICTROSAs) operating at up to 800Gbps in telecom and DCI applications.

The MATA-009806 is a dual-channel linear TIA for coherent receivers supporting baud rates up to 96Gbaud and complex modulation formats such as 64QAM. With built-in automatic gain control (AGC) and transimpedance gain of up to 5kΩ, the TIA has 60GHz of bandwidth and ultra-low noise to support applications from long haul to DCI. The device is available in bare die form.

The MAOM-009408 is a high-performance quad-channel modulator driver also supporting 96Gbaud symbol rates. It has up to 19dB of gain with 15dB of gain range and a maximum output voltage of 3Vpp differential. The device is designed to be directly DC coupled to an optical modulator for maximum bandwidth, minimum size and minimum power dissipation. The device is available in bare die form.
