APPLICATIONS

USB2.0 High-speed Serial Link at 480 Mbps and 12 Mbps for Host and Device Functionality. 

Can be used in Host Controllers, Hub Applications and device functions where USB 2.0 Transceiver is required.

GENERAL DESCRIPTION

USB 2.0 HOST/DEVICE/ OTG Transceiver is a fully integrated PHY Core which is a super-set 

of HOST and DEVICE PHY with High Speed (HS), Full-Speed (FS) and Low-Speed Transceivers 

integrated with On The Go Functionality and is compliant with the USB 2.0 Specification and

 latest Revision of the On the Go and UTMI+ Specifications. It includes Data Pulsing, VBUS

 Pulsing, VBUS Comparators for Session Detection to support HNP (Host Negotiation Protocol) 

and SRP (Session Request Protocol), Clock/Data Recovery, on-chip PLL, Integrated & Calibrated 

Termination and Pull-Up/Down Resistors with full Analog Transceiver functionality for the Complete USB 2.0 PHY.

 

USB 2 HOST / DEVICE / OTG transceiver has standard UTMI and UTMI+ (Version 1.0 Level 3) where needed so that ASIC vendors are isolated from the high speed and analog circuitry associated with the transceiver, thus reducing the design risk and

fastening the design cycle. The core's major blocks are clock data recovery for FS/HS, PLL, transceiver state machines, data encoder/decoder and High-Speed, Full-Speed/Low-Speed analog transceiver.
