Terminus Circuits Team
who are we

Bangalore‑based semiconductor IP company

Terminus Circuits is a Bangalore‑based semiconductor IP company with deep expertise in high‑speed serial links and protocol‑based interface IPs. We design, develop and deliver SerDes, PHY for PCIe, USB, MIPI, Ethernet and associated analog IP (PLLs, biasing subsystems) as part of our IP licensing.

With 50+ IPs and multiple tape-outs in major foundries (TSMC, Samsung & GF) across nodes from bulk silicon to FinFet, our team of seasoned engineers ensures first-pass success for complex semiconductor projects.

Our mission is to reduce design risk and accelerate time-to-market by delivering low-power, high-performance IP with responsive technical support and flexible licensing.

Frequently Asked Questions

Detailed answers about IP licensing, support, and customization

We offer a comprehensive portfolio of high-speed serial links Phy IP:
  • SerDes IP: 1G to 64G multi-protocol (PCIe, Ethernet, USB, MIPI Mphy)
  • Clocking: Low-jitter PLLs, DLLs, clock generators, jitter attenuators
  • Data converters: High-speed ADCs/DACs for communication and sensing
  • Power management/biasing: high precisions current and voltage biasing, monitoring circuits.
  • I/Os: GPIO, multi-voltage I/O, High speed IOs
  • Interface IP: PCIe, Ethernet, USB, MIPI PHYs

All IPs are available with complete documentation, integration guides, and silicon proven data.

Our IPs are silicon/CAD proven across a wide range of nodes and foundries:

  • TSMC: 65nm, 55nm, 40nm, 28nm, 22nm, 16nm, 12nm
  • GlobalFoundries: 55nm, 40nm, 28nm, 22nm, 12nm
  • Samsung: 28nm, 14nm

We continuously add support for new nodes. Contact us for specific node availability.

Absolutely. We offer extensive customization to meet your protocol/specific PPA (power, performance, area) targets:

  • Customizing PLL loop bandwidth, output frequencies, and jitter performance
  • Adjusting I/O drive strength, voltage levels, and slew rate
  • Power management IP modifications (output voltage, current limit, sequencing)
  • Adding or removing features to match your system requirements
  • Porting IP to a different process node or foundry (Turnkey basis)

Our experienced analog/mixed-signal Serdes design team works closely with your engineers to deliver optimized solutions.

We offer flexible licensing options to suit different project needs:

  • Per-project license: One-time fee for use in a single product/tape-out
  • Multi-project license: Covers up to a specified number of tape-outs or products
  • Enterprise / unlimited use license: Unlimited usage across all your projects for a fixed term
  • Royalty-based: Low upfront fee plus per-unit royalties for high-volume products
  • IP Buyout option: Perpetual license model, all database provided and limited support.
  • Joint Development: Customer specific IP development, customer can use it for their own modifications across multiple projects, no-sub-licensing allowed, IPR will be with Terminus Circuits.
  • Evaluation / NDA option: Preliminary models and datasheets under NDA for evaluation

All licenses include the full IP deliverables, documentation, and technical support.

Yes, comprehensive support is included with every IP license. Our support includes:

  • Onsite or remote application engineering assistance
  • Help with IP integration into your SoC/ASIC design flow
  • Support for simulation, characterization, and silicon bring-up
  • Access to our design and verification teams for troubleshooting
  • Regular status updates and design reviews if needed
  • Extended support for maximum of couple of weeks and if travel to onsite required at customer expenses

We pride ourselves on being responsive — most queries are addressed within a week.

Every IP we deliver has been silicon-verified. Our proven track record includes:

  • Our Customer tape-outs across various nodes and our testchips.
  • Multiple test chips demonstrating performance across PVT corners
  • Characterization reports available under NDA
  • Compliance testing for standards (PCIe, USB, MIPI, Ethernet)
