Transimpedance Amplifiers (TIA)
High-performance TIAs for next-generation optical receivers.
Coherent’s high-speed transimpedance amplifiers (TIAs) deliver best-in-class noise performance, excellent linearity and power efficiency for data rates up to 224Gbps PAM-4 and up to 64GBaud coherent modulation. These enable high-performance receiver operation over a wide optical power range.
Designed for AI infrastructure, hyperscale data centers, and high-speed optical modules - both IMDD and coherent - our feature-rich TIAs enable system designers to accelerate the develoment of next-generation high-performance receivers while optimizing solution cost and power efficiency.
Key Features
- Deliver best-in-class noise- and linearity performance for high-sensitivity, high-speed optical receivers.
- Automatic gain control that supports a large range of optical signal levels (OMA).
- Serial bus interface for control and analog/digital performance monitoring interfaces
- Combine high-performance with excellent power efficiency.
- Support for symbol rates from 28GBaud to 112GBaud IMDD and 64GBaud coherent (DCO).
