Macom has expanded  its portfolio of transimpedance amplifiers (TIAs) and launched a 25G APD photodiode and 25G Fabry-Perot laser photodiode, aimed at 5G applications and data centres.

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 to customers in bare die form.

The MAOM-009408 is a high-performance quad channel modulator driver also supporting 96Gbaud symbol rates. The part has up to 19 dB of gain with 15 dB of gain range and a maximum output voltage of 3 Vpp 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 to customers in bare die form.

MACOM says today’s increased demand for data capacity in metro and Data Centre Interconnect (DCI) applications is driven by new trends like the Internet of Things (IoT), autonomous vehicles, virtual reality and artificial intelligence. As the 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.

The MATA-05817 delivers low noise performance less than 2 uA RMS typical and supports bandwidth up to 35 GHz. The TIA supports high throughput optical data links in a very low power profile, optimal for use in high density Optical Data Centre interconnects. The device is intended for 50G, 100G, 200G and 400G receivers using multilevel modulation such as PAM4.

The MATA-38134 is a quad 26/53GBaud linear PAM4 TIA with automatic gain and integrated AGC loop. The TIA consumes very low power and is primarily targeted for single-mode fibre applications. The TIA has 500um anode to anode spacing which allows customers to place two devices within the QSFP-DD form factor enabling 800Gbps applications. The MATA-05817 and the MATA-38134 devices include RSSI for photo-alignment and power monitoring and I2C control of bandwidth, output amplitude, peaking, LOS, gain and other parameters.

The APD28A is a back-illuminated 25G APD covering both O- and C-Bands with a usable wavelength range of 1250nm to 1650nm. The Photodiode features greater than 20GHz (3dB) bandwidth, with very high sensitivity of -22dBm when coupled to a low noise amplifier for transmission applications. The device performance enables customers to design optical sub-assemblies and transceivers suitable for 5G wireless mid-haul and long-haul networks, and extended reach (ER4) applications for 100Gbps, 200Gbps and 400Gbps Data Centre applications. MACOM will offer the 25G APD as bare die and a chip-on-carrier format to provide maximum design flexibility to customers.

The MAOD-131F25 is a directly modulated high speed 25Gbps 1310nm Fabry-Perot laser diode with a wide operating temperature range of -40 oC to +95oC. The device leverages MACOM’s patented and proven Etched Facet Technology (EFT) enabling scalability to high volume manufacturing. The 25G FP laser is ideally suited to enable customers’ 5G LTE fronthaul short reach applications as well as low cost 100Gpbs parallel single mode fibre (PSM4) application for datacentres. MACOM will offer the 25G Fabry-Perot laser in a TO-Can package to complement customer requirements and accelerate time to market.
