CY7C68000-56LFXCT

Overview

The CY7C68000-56LFXCT is a USB 2.0 UTMI transceiver manufactured by Infineon Technologies (formerly Cypress Semiconductor). It operates at 3.3V with a supply voltage range of 3.0V to 3.6V and an ambient temperature range of 0°C to +70°C. The device supports High Speed (480 Mbps) and Full Speed (12 Mbps) signaling, utilizing an internal PLL driven by a 24-MHz crystal. It features an 8-bit (60 MHz) or 16-bit (30 MHz) parallel interface and includes internal 1.5kΩ pull-up resistors on DPLUS. The component is housed in a 56-pin QFN package.

Feature Summary

• UTMI-compliant physical layer interface certified for USB 2.0 device operation
• Integrated serial-to-parallel and parallel-to-serial conversion capabilities
• Internal impedance termination and 1.5kΩ pull-up resistor on DPLUS
• Configurable operational modes including soft disconnect and test modes

Applications

• DSL modems
• ATA interface devices
• Memory card readers
• Legacy conversion devices
• Cameras and scanners

Procurement Notes

Verify the specific ordering suffix 'CT' corresponds to the Tape and Reel packaging format as defined in the official datasheet. Confirm that the component meets RoHS3 compliance requirements for lead-free manufacturing. Ensure the procurement source provides valid traceability documentation for this discontinued product line.

Selection Notes

Select this component when a dedicated USB 2.0 high-speed physical layer interface is required separate from the digital controller logic. It is suitable for designs needing a standard UTMI interface to reduce development risk associated with analog USB components. Verify that the host system can support the required 24-MHz external crystal oscillator frequency.

Part Context

This part belongs to the EZ-USB TX2 family of USB 2.0 transceivers. It serves as the physical layer bridge between the USB bus and a Serial Interface Engine (SIE). The device allows designers to keep complex high-speed analog USB circuitry external to the main digital ASIC, thereby decreasing overall development time.
