Macom Extends Transimpedance Amp Range
Low noise amps cover 100G to 800G applications
Macom Technology has announced availability two new transimpedance amplifiers (TIAs) optimised for use in optical networking applications ranging from 100Gbps DR1 to 800Gbps DR8 and FR8. The new TIAs are available today in flip chip and wire bonding packaging options for fast, flexible deployment in QSFP, QSFP-DD and OSFP optical modules.
The rapid evolution to single lane 100G and multiple lanes 200G, 400G and 800G connectivity is increasing the demand for high-performance, power-efficient optical components needed to maximise bandwidth density in the Cloud data centre. Macom's extended TIA family, complemented by a range of interoperable components, is designed to help customers accelerate this transition.
The MATA-05817 delivers low noise performance less than 2 µA 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.
Both devices include RSSI for photo-alignment and power monitoring and I2C control of bandwidth, output amplitude, peaking, LOS, gain and other parameters.
