The Cypress EZ-USB TX2™ is a USB 2.0 transceiver, supporting 16-bit 30MHz or 8-bit 60MHz parallel interfaces.
The CY7C68000 TX2™ USB 2.0 UTMI transceiver provides a high‑speed physical layer interface for USB devices. It supports both full‑speed (12 Mbps) and high‑speed (480 Mbps) operation, includes internal 1.5 kΩ pull‑up on DPLUS, and features a PLL that multiplies a 24 MHz crystal to the required 30 MHz or 60 MHz parallel bus clocks.
The device is offered in two 56‑pin packages (SSOP and QFN) and includes a full pin‑out table, absolute maximum ratings, DC characteristics, and package‑mounting guidelines. Electrical specifications such as supply voltage (3.0 V–3.6 V), operating temperature (‑65 °C to +150 °C), and oscillator requirements are detailed for designers.
