Product details
Overview
CY7C68000-56PVXCT from Cypress Semiconductor is a USB 2.0 UTMI-compliant transceiver IC that implements the physical layer (PHY) for high-speed (480 Mbps) and full-speed (12 Mbps) USB device operation. It provides serial-to-parallel conversion via an 8-bit/60-MHz or 16-bit/30-MHz parallel interface, integrates internal 1.5-kΩ DPLUS pull-up and USB line terminations, and operates from a single 3.3 V supply with an on-chip 24-MHz crystal oscillator interface. It is used in USB peripheral controllers for DSL modems and memory card readers.
For engineers reviewing the CY7C68000-56PVXCT datasheet, CY7C68000-56PVXCT pinout, CY7C68000-56PVXCT application, or CY7C68000-56PVXCT equivalent, key selection criteria include UTMI v1.05 compliance, dual-speed (HS/FS) transceiver support, integrated analog termination, clock recovery capability, and 56-pin SSOP package compatibility with industrial USB peripheral designs.
Technical Context
The CY7C68000 implements a dual-mode USB 2.0 PHY with separate high-speed and full-speed transceiver paths selected by XcvrSelect and TermSelect control inputs. Its on-die PLL multiplies a 24-MHz crystal input to generate 30 MHz (16-bit mode) or 60 MHz (8-bit mode) UTMI clock outputs synchronized to data transfers.
It performs bit stuffing/unstuffing and NRZI encoding/decoding in normal mode (OpMode = 00), supports soft disconnect (OpMode = 01), and allows raw J/K state transmission (OpMode = 10). LineState[1:0] outputs provide real-time, CLK-synchronized reflection of DPLUS/DMINUS states for protocol monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed Support | High-speed (480 Mbps) and full-speed (12 Mbps); no low-speed mode - enables dual-rate peripheral connectivity without external speed negotiation logic. |
| Data Interface | Configurable 8-bit bidirectional at 60 MHz or 16-bit bidirectional at 30 MHz - matches ASIC/FPGA bus timing margins while minimizing pin count. |
| Supply Voltage | 3.3 V ±10% - compatible with standard digital I/O domains and eliminates need for level-shifting circuitry. |
| Internal Terminations | Integrated 1.5-kΩ DPLUS pull-up and USB differential line terminations - removes four external resistors and ensures USB 2.0 electrical compliance. |
| Clock Source | 24-MHz ±100 ppm parallel-resonant crystal with on-chip oscillator - eliminates external clock generator and reduces BOM cost and layout area. |
| UTMI Compliance | UTMI+ v1.05 specification compliant - guarantees interoperability with standard USB 2.0 link-layer controllers and simplifies system-level validation. |
Pinout & Package
The CY7C68000-56PVXCT is housed in a 56-pin SSOP (Shrink Small Outline Package) with 0.5 mm pitch, optimized for surface-mount assembly and thermal performance in USB peripheral modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D[15:0] | Bidirectional data bus | Carries parallel USB packet payload; width and clock rate configured via DataBus16_8 (16-bit @ 30 MHz or 8-bit @ 60 MHz). |
| CLK | Output clock | Synchronous timing reference for data capture; frequency determined by DataBus16_8 and PLL output (30/60 MHz). |
| XcvrSelect / TermSelect | Mode control inputs | Select HS/FS transceiver path and termination type independently - enables dynamic speed switching during enumeration or suspend/resume. |
| LineState[1:0] | Output status signals | Real-time, CLK-synchronized mirror of DPLUS/DMINUS single-ended states (J/K/SE0) - used for USB state machine debugging and protocol analysis. |
| XTALIN / XTALOUT | Clock oscillator interface | Connects to 24-MHz fundamental-mode crystal; internal oscillator eliminates need for external clock source or buffer. |
| Reset | Active-HIGH reset input | Asynchronous chip reset with hysteresis; initiates full internal state initialization and PLL stabilization (~200 µs after VCC stable). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB 2.0 analog PHY | Removes external transceiver IC and discrete termination resistors - reduces PCB area, component count, and signal integrity risk. |
| UTMI+ v1.05 interface | Standardized parallel bus with defined timing and signaling - enables plug-and-play integration with USB controller ASICs and FPGA soft cores. |
| On-chip 24-MHz oscillator | Eliminates external clock generator and associated decoupling - lowers system cost and improves time-to-market for USB peripheral designs. |
| Three operational modes (OpMode) | Supports normal operation, soft disconnect (bus unplug emulation), and raw J/K transmission (test/debug) - enhances development and compliance testing flexibility. |
| Internal 1.5-kΩ DPLUS pull-up | Factory-trimmed resistor meets USB 2.0 specification - ensures reliable device enumeration without external component tolerance dependencies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 PHY transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISP1504HN | Single 3.3 V supply, UTMI+ v1.05 compliant, but requires external 48-MHz clock or crystal; no integrated DPLUS pull-up. | Lacks internal oscillator and pull-up - increases BOM count and layout complexity for cost-sensitive consumer devices. | Choose when existing 48-MHz clock infrastructure is available and board space permits external components. |
| USB3300-EZK | Supports USB 2.0 + USB 3.0 SuperSpeed; requires 1.05 V core + 3.3 V I/O supplies; includes integrated USB 3.0 PHY. | Higher pin count (64-QFN), dual-supply design, and USB 3.0 feature set - over-spec for USB 2.0-only applications. | Choose only if future USB 3.0 upgrade path or backward-compatible SuperSpeed support is required. |
Compared with ISP1504HN and USB3300-EZK, the CY7C68000-56PVXCT delivers optimal balance of integration (internal oscillator, pull-up, terminations), USB 2.0 certification, and SSOP packaging - making it ideal for cost-constrained, space-limited USB peripheral designs requiring proven reliability and minimal external components.

FAQ
What USB speeds does the CY7C68000-56PVXCT support?
The CY7C68000-56PVXCT supports USB 2.0 high-speed (480 Mbps) and full-speed (12 Mbps) signaling modes. It does not support low-speed (1.5 Mbps) operation. Speed selection is controlled by the XcvrSelect and TermSelect pins, and the device complies with USB 2.0 specification requirements for both modes including HS identification and resume signaling.
Does the CY7C68000-56PVXCT require external USB line termination resistors?
No. The CY7C68000-56PVXCT integrates all required USB 2.0 terminations internally, including the 1.5-kΩ pull-up resistor on DPLUS and differential line terminations. These are factory-trimmed to meet USB 2.0 electrical specifications, eliminating the need for four external resistors and reducing PCB layout complexity.
What clock source options are supported by the CY7C68000-56PVXCT?
The CY7C68000-56PVXCT supports a 24-MHz parallel-resonant fundamental-mode crystal connected to XTALIN/XTALOUT, or an external 24-MHz square-wave clock driven into XTALIN. The on-chip oscillator and PLL generate the required 30-MHz or 60-MHz UTMI interface clock based on the DataBus16_8 setting - no external clock generator is needed.
How is the 8-bit vs. 16-bit data interface configured on the CY7C68000-56PVXCT?
The DataBus16_8 pin selects the interface width: logic HIGH enables 16-bit bidirectional mode at 30 MHz; logic LOW enables 8-bit bidirectional mode at 60 MHz. This configuration is sampled once at power-on reset and remains static thereafter. ValidH indicates high-byte validity in 16-bit mode, and Uni_Bidi further enables 8-bit unidirectional operation when asserted.
