CY7B992-2JCT

Overview

The CY7B992-2JCT is a programmable skew clock buffer manufactured by Cypress Semiconductor Corp. It operates as a fanout distribution and zero delay buffer with one circuit, providing an input-to-output ratio of 1:8. The device accepts CMOS inputs and generates CMOS outputs, supporting a supply voltage range of 4.5V to 5.5V. It is housed in a 32-LCC (J-Lead) surface-mount package, specifically the 32-PLCC form factor measuring 11.43x13.97 mm. The component is designed for commercial applications within an operating temperature range of 0°C to 70°C.

Feature Summary

• Programmable Skew Clock Buffer with user-selectable output functions
• Zero Delay Buffer architecture ensuring minimal input-to-output latency
• CMOS input and output logic levels compatible with standard digital systems

Applications

• High-performance computer system timing optimization
• Driving terminated transmission lines with impedances as low as 50Ω
• System integrator clock distribution networks requiring controlled skew

Procurement Notes

Verify the specific suffix 'JCT' against official Cypress documentation to confirm if it denotes tape-and-reel packaging or other handling variations distinct from the bulk 'JC' variant. Confirm end-of-life status and lead-free compliance requirements prior to procurement planning.

Selection Notes

Select this component when precise control over output skew is required alongside zero-delay buffering capabilities. Ensure the design environment supports the specified 4.5V to 5.5V supply voltage and that the 32-PLCC package fits the available PCB footprint constraints.

Part Context

This part belongs to the CY7B991/CY7B992 family of programmable skew clock buffers. These devices are engineered to provide multiple output drivers arranged in pairs, allowing system designers to optimize timing margins in complex digital architectures through selectable skew and frequency multiplication options.

Replacement Considerations

The QS5992-5JRX is documented as pin-compatible with the CY7B992 series. Verify electrical parameter alignment, particularly regarding drive strength and skew specifications, before substituting.
