CY7C68000-56PVXC

Overview

The CY7C68000-56PVXC is a USB 2.0 UTMI transceiver manufactured by Infineon Technologies (formerly Cypress Semiconductor). It provides a high-speed physical layer interface compliant with the Transceiver Macrocell Interface specification version 1.05. The device supports both High Speed (480 Mbps) and Full Speed (12 Mbps) data rates, performing serial-to-parallel and parallel-to-serial conversions. It features an 8-bit at 60 MHz or 16-bit at 30 MHz parallel data bus interface. Operating on a 3.3V supply voltage within a 3.0V to 3.6V range, it includes internal impedance terminations and a 1.5k-ohm pull-up resistor. The component utilizes a 56-pin SSOP package and requires an external 24-MHz crystal oscillator.

Feature Summary

• UTMI-compliant/USB-2.0-certified for device operation
• Supports detection of USB reset, suspend, and resume
• Internal termination resistors including 1.5K-ohm pull up on DPLUS
• Synchronous field and EOP detection/generation

Applications

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

Procurement Notes

Verify the manufacturer origin as Infineon Technologies, noting the historical transition from Cypress Semiconductor. Confirm the specific ordering suffix PVXC indicates the lead-free 56-pin SSOP package variant. Ensure compatibility with the required 24-MHz external crystal specifications and check for any end-of-life notifications associated with this discontinued component family.

Selection Notes

Select this component when a dedicated USB 2.0 physical layer transceiver is required for custom ASIC designs. It is suitable for applications needing a standard UTMI interface to offload complex analog USB components. Consider the 56-pin SSOP package constraints and the necessity for an external 24-MHz crystal. Evaluate power consumption requirements against the specified 175 mA in HS mode and 90 mA in FS mode.

Part Context

The CY7C68000 belongs to the EZ-USB TX2™ family of USB 2.0 transceivers. This series was designed to provide a certified physical layer interface for system designers integrating USB capabilities into digital logic. The -56PVXC suffix specifically denotes the lead-free version housed in a 56-lead Shrunk Small Outline Package (SSOP), distinguishing it from QFN variants or non-lead-free versions.

Replacement Considerations

Public confirmed substitute part numbers include CY7C68000-56LFXC (56-pin QFN Pb-Free) and CY7C68000-56PVC (56-pin SSOP non-Pb-Free). Verify pinout compatibility if switching between SSOP and QFN packages.
