Canonical technology and its architecture/integration role are recorded. The offered delivery is confirmed against the exact release before licensing. This is a controlled-portfolio summary, not a fresh execution of the chip qualification flow. [Explore the evidence center](https://garmolabs.com/evidence) [Qualification record](https://garmolabs.com/qualification/ip-ip-2092) ### Release-specific qualification Control/model IP does not establish analog PHY, electrical, RF or standards compliance. Qualified third-party or foundry collateral may be required. Canonical record: P3 / REPRESENTATIVE ARCHITECTURE RTL — concrete integration specification and synthesizable RTL shell/representative datapath only; all frequency, throughput, power, area, jitter and standards-superiority figures remain architecture targets until the required evidence hierarchy closes. Analog/custom production claims require transistor-level/custom-layout, extracted PVT/Monte-Carlo and silicon characterization. A PATH THAT FITS THE PROJECT ## Build with Garmo-PLL-Frac.
