The Cypress MoBL-USB™ TX2 is a Universal Serial Bus 2.0 UTMI Transceiver that supports both high-speed (HS) and full-speed (FS) modes. It operates at 3.3V and offers 8-bit unidirectional, 8-bit bidirectional, or 16-bit bidirectional external data interfaces. The TX2 also supports data and clock recovery, and can detect USB reset, suspend, and resume events.
The CY7C68000A is a USB 2.0 UTMI‑compliant transceiver that supports both Full‑Speed (12 Mbps) and High‑Speed (480 Mbps) operation. It offers 8‑bit (60 MHz) or 16‑bit (30 MHz) parallel interfaces, tri‑state capability for bus sharing, and internal termination for D+ and D‑ lines. The device operates from a 3.3 V supply and includes on‑chip PLL, clock recovery, and bit‑stuffing logic.
Typical applications include mobile phones, PDAs, MP3 players, cameras, scanners, and networking equipment. The document details pin assignments for the 56‑pin QFN and VFBGA packages, electrical characteristics, absolute maximum ratings, ordering information, and PCB layout recommendations to ensure reliable high‑speed USB performance.
