Optoelectronic Interface Solutions
Omni Design's Transmitter Driver and Receiver TIA IP portfolio delivers the analog front-end building blocks for next-generation optical interconnects, spanning 64G NRZ to 224G PAM4 data rates in TSMC N3P. Each linear driver converts standard-swing SerDes outputs into high-swing, low-noise signals optimized for direct silicon-photonic modulator drive, while each transimpedance amplifier converts photodetector current into clean, equalized voltage output ready for digital SerDes ingestion. Engineered for co-packaged optics, near-packaged optics and pluggable transceivers, these hard macros combine industry-leading power efficiency, wide bandwidth, and integrated calibration and telemetry — enabling customers to accelerate time-to-market for 800G, 1.6T, and beyond.
Matched receive (TIA) and transmit (driver) IP for complete optical front-ends.
Aligned with the OCI (Optical Compute Interconnect) approach, in two flavors - 64G NRZ (slow & wide) and 224G PAM4 (fast & narrow).
Silicon-photonics-ready.
