CY7C68000A-56BAXC - USB 2.0 High-Speed Transceiver | Infineon
N.º de pieza: CY7C68000A-56BAXC ✓ ActivoCY7C68000A-56BAXC Descripción general
A USB transceiver is the physical-interface portion of a USB controller. It manages differential data signaling between a host or peripheral controller and a USB connector while presenting a parallel bus to the surrounding digital logic. The CY7C68000A-56BAXC supports the USB 2.0 specification revision indicated by the manufacturer and accommodates two parallel-interface operating modes, allowing the host logic to balance bus width against clock rate.
The principal functional features include USB 2.0 operation, serial and deserializer functions, and the dual 16-bit/30 MHz and 8-bit/60 MHz parallel-interface options. The 56-VFBGA package supports compact PCB placement while exposing the device through a high-density ball-grid footprint. Its operating details must be checked against the manufacturer datasheet for the exact voltage limits, temperature range, clocking requirements, and signal timing of the selected board revision.
Technically, the part sits between a parallel USB controller engine and the external USB data path. Its serializer and deserializer functions translate between the differential serial USB signaling domain and the internal parallel data bus. At 30 MHz, the interface width is 16 bits; at 60 MHz, the interface width is reduced to eight bits. This two-mode architecture is valuable when a design must balance transfer throughput, clock speed, logic utilization, and signal-timing margin.
Typical uses include USB 2.0 peripheral controllers, portable data-acquisition equipment, storage adapters, test and measurement systems, and compact external-access products. In these systems, the device can provide the protocol-facing transceiver layer while a separate controller or programmable logic fabric handles packet processing, descriptors, enumeration, and application-specific data transfer.
Layout is the primary implementation concern for this device. Differential USB routing, ball-grid escape routing, controlled-length clock and data paths, solid ground and power distribution, and close placement of decoupling components should follow the manufacturer’s reference layout and stack-up guidance. Do not substitute generic USB routing practices for the device-specific schematic and layout recommendations in the datasheet.
This page combines the documented USB 2.0 interface modes, 56-VFBGA packaging, lifecycle considerations, sourcing workflow, and drop-in compatibility review into an engineering-focused reference. It also distinguishes confirmed drop-in alternatives from merely similar interface controllers, helping designers avoid adopting a part that has a related function but lacks verified footprint and pin compatibility.

Aplicaciones típicas
CY7C68000A-56BAXC es adecuado para 6 aplicacións: Compact USB 2.0 Peripheral Controller, Portable Data-Acquisition System, USB Storage and Media Adapter, Test and Measurement Instrument, Industrial USB-to-Embedded Interface, External Network or Protocol Adapter.
Compact USB 2.0 Peripheral Controller
The CY7C68000A-56BAXC fits a compact peripheral that separates USB 2.0 serial signaling from parallel controller logic. Its documented 16-bit interface at 30 MHz provides broad word-level parallelism, while the 8-bit interface at 60 MHz gives the design a higher-speed but narrower internal bus option. Place the device near the USB connector and route its differential pair as a controlled-impedance USB channel. This arrangement lets the surrounding controller concentrate on descriptors, endpoints, and application data while the transceiver handles the serial-deserializer function.
Recomendado
Portable Data-Acquisition System
A portable data-acquisition product can use the CY7C68000A-56BAXC to transfer sampled data through a USB 2.0 connection while a parallel interface connects to an FPGA or embedded controller. The 16-bit/30 MHz mode is suitable for designs that favor wider data transfers, whereas the 8-bit/60 MHz mode supports a narrower interface operating at twice the clock frequency. Selection should reflect the endpoint throughput, FPGA timing margin, memory interface architecture, and cable-length behavior of the finished portable product.
Recomendado
USB Storage and Media Adapter
The CY7C68000A-56BAXC can serve as the high-speed USB transceiver in a storage or removable-media adapter when a separate controller implements the storage protocol and data buffering. The device supports USB 2.0 operation and provides two parallel-interface choices, allowing designers to connect the bus directly to a controller operating at 16 bits and 30 MHz or 8 bits and 60 MHz. Practical implementation still requires careful USB trace geometry, connector protection, stable reference clocking, and a firmware architecture that handles enumeration and sustained-transfer flow control.
Recomendado
Test and Measurement Instrument
Test and measurement instruments often benefit from separating the USB physical interface from a high-speed acquisition or control engine. The CY7C68000A-56BAXC offers an 8-bit interface at 60 MHz for designs needing a faster parallel clock, or a 16-bit interface at 30 MHz for systems that prefer wider transfers. The choice should be based on the instrument’s sustained throughput, synchronization requirements, FPGA resources, and timing margins. USB signal integrity and clock cleanliness are especially important when the device also handles precision analog measurement circuitry.
Recomendado
Industrial USB-to-Embedded Interface
An industrial controller can use the CY7C68000A-56BAXC when it requires a dedicated USB 2.0 transceiver and a deterministic parallel connection to programmable logic or an embedded processor. The 56-VFBGA package supports compact board layouts, while the two parallel modes allow optimization for either bus width or clock rate. In an industrial enclosure, pay particular attention to conducted noise from external cables, ESD protection strategy, ground-plane continuity, and operating-temperature requirements. Firmware should also implement robust enumeration and recovery behavior for field-deployed USB links.
Recomendado
External Network or Protocol Adapter
The CY7C68000A-56BAXC can support external adapters that add USB connectivity to a proprietary serial, storage, or industrial protocol controller. Using the 16-bit/30 MHz mode may reduce bus multiplexing in the host logic, while the 8-bit/60 MHz mode may simplify timing closure in a high-speed parallel subsystem. Interface selection should be validated against maximum packet rates and sustained host transfers rather than only peak bus frequency. The PCB also needs a compliant USB connection, tested power distribution, and firmware that recovers cleanly from suspend, reset, and cable-removal events.

Notas de diseño
Route the USB differential pair as a controlled-impedance, tightly coupled path with minimal stubs and no right-angle transitions. Follow the manufacturer’s recommended BGA escape geometry and land pattern rather than substituting a generic 56-ball footprint. Keep connector protection, the transceiver, and the USB route in the same region of the PCB, and provide a continuous ground reference beneath the pair. After stack-up definition, verify differential impedance, return-path continuity, and the clearance rules used by the USB connector and protection components.
Choose the parallel operating mode by system timing rather than by raw clock frequency. The 16-bit/30 MHz mode reduces bus width but requires twice the data-transfer parallelism of the 8-bit/60 MHz mode; the 8-bit/60 MHz mode may ease clocking while increasing the number of transfers required. Review setup and hold timing at the transceiver and controller interfaces, keep the clock distribution clean, and avoid routing the parallel bus through uncontrolled test pads or long connector paths.
Place decoupling and bypass components close to the device’s power and ground balls using the manufacturer’s reference layout. Because the 56-VFBGA has no perimeter access to every ball, use the recommended fanout or via-in-pad construction appropriate for the assembly process. Separate sensitive clock and parallel-data routing from noisy power-stage currents. Check the BGA assembly profile, solder-paste footprint, stencil apertures, and package orientation before releasing the PCB for production.
Do not treat a matching 56BAXC suffix as proof of drop-in compatibility. Before replacing the device, compare every ball name and function, supply voltage, operating temperature, clock requirements, control defaults, USB electrical parameters, and parallel timing. Firmware must also be checked for any controller-specific differences. A board-level substitution is justified only after the manufacturer documentation and measured power, clock, and signal behavior validate the complete configuration.
