USB 2.0 nanoPHY in SMIC (65nm)
Overview
The Synopsys USB 2.0 nanoPHY provides designers with a complete Physical Layer (PHY) IP solution, designed for low-power mobile and consumer applications such as feature-rich smartphones, digital cameras, and portable audio/video players. The Synopsys USB 2.0 nanoPHY IP delivers a low-power, small-area solution for longer battery life and lower silicon cost. Designed for high yield, the Synopsys USB 2.0 nanoPHY implements architectural features that make it less sensitive to variations in foundry process, device models, package and board parasitics. The Synopsys USB 2.0 nanoPHY builds on years of success with Synopsys’ silicon-proven USB 2.0 PHY IP product line, which has been ported to more than 70 process node and configuration combinations. When combined with the Synopsys Controller IP and VC Verification IP, the Synopsys USB 2.0 nanoPHY delivers a complete solution for low-power, area-efficient system-on-chip (SoC) designs.
Key Features
- Complete mixed-signal physical layer for single-chip USB 2.0 OTG and non-OTG applications
- Low power: <100mW (during HS packet transmission)
- Small area: ~ 0.6mm2
- High yield—Architecture designed to improve key operating margins by having less sensitivity to variations due to foundry process, chip and board parasitics, and process device model variations
- Low pin count
- USB 2.0 Transceiver Macrocell Interface (UTMI+ Level 3) specification 8-bit interface at 60 MHz operation and 16-bit interface at 30 MHz operation
- Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operation is compliant to the USB OTG Supplement
- Supports all OTG features, including Host Negotiation Protocol (HNP) and Session Request Protocol (SRP)
- Designed for rapid integration with Synopsys’ USB device and host controllers
