GENERAL DESCRIPTION

GL800HT25 is a high performance USB 2.0 Transceiver compliant with the UTMI (USB 2.0 Transceiver Macrocell Interface) Specification proposed by Intel. The UTMI specification defines a standard interface to USB 2.0 high-speed transceivers that enables common design across prototype and production implementations.
