USB 2.0 PHY

Overview

Key Features

• ? 480-Mbps high-speed, 12-Mbps full-speed, and 1.5-Mbps low-speed serial (Host mode only) data transmission rates
• ? Supports high-speed power modes: suspend, resume, and remote wakeup.
• ? USB 2.0 test modes
• ? 45-? termination, 1.5-k? pull-up and 15-k? pull-down resistors with support for independent control of the pull-down resistors
• ? 8/16-bit unidirectional parallel interfaces for HS, FS, and LS (Host mode only) modes of operation in accordance with the UTMI+ specification
• ? Dual (HS/FS) mode host/device support (LS operation is not supported for device applications)
• ? Data recovery from serial data on the USB connector
• ? SYNC/End-of-Packet (EOP) generation and checking
• ? Bit stuffing and unstuffing, and bit-stuffing error detection
• ? Non Return to Zero Invert (NRZI) encoding and decoding
• ? Bit serialization and deserialization
• ? Holding registers for staging transmit and receive data
• ? Logic to support suspend, resume, and remote wakeup operations
• ? VBUS threshold comparators
• ? Parameter override bits for optimal yield and interoperability
• ? Fully integrated short-to-5-V and short-to-ground protection for D+ and D– lines (requires only global ESD and 5-V-compliant DP/DM pads)

Deliverables

• We offer high-speed interface IPs designed for 28~90nm fabrication processes in various foundries. We can also customize porting IPs for customers requiring 90~180nm fabrications and support more advanced processes as needed.
