CY7B991V-5JXC

Overview

The CY7B991V-5JXC is a zero-delay programmable PLL clock buffer from Infineon Technologies' RoboClock series. It operates on a single 3.3V supply with a range of 2.97V to 3.63V, supporting output frequencies up to 80 MHz. The device features one circuit with an 8:8 input-to-output ratio and LVTTL outputs. Housed in a 32-PLCC package, it is designed for surface mount installation within an operating temperature range of 0°C to +70°C.

Feature Summary

• Zero-delay programmable PLL architecture
• 8:8 input-to-output frequency ratio
• LVTTL output logic levels
• Single circuit configuration

Applications

• System clock distribution networks
• Digital signal processing timing synchronization
• Embedded system clock buffering

Procurement Notes

This component is identified as an existing product but has a status of discontinued or limited availability. Verification of current stock levels and end-of-life timelines through official Infineon channels is required before procurement planning.

Selection Notes

Select this part when an 8-channel LVTTL clock buffer with zero-delay characteristics is needed. Ensure the design supports 3.3V logic levels and the 32-PLCC surface-mount package fits the PCB layout constraints.

Part Context

Part of the RoboClock family, which specializes in programmable clock management solutions. This specific model provides deterministic latency for synchronous digital systems requiring precise clock alignment across multiple branches.

Replacement Considerations

As the component is marked as discontinued, direct substitutes must be verified against pinout compatibility and electrical specifications. Consult Infineon's obsolescence notices for recommended alternative part numbers.
