CY7B991V-2JC

Overview

The CY7B991V-2JC is a zero-delay programmable PLL clock buffer from Infineon's 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 an 8:8 input-to-output ratio and provides LVTTL outputs. Packaged in a 32-LCC (J-Lead) surface-mount case, it functions within a commercial temperature range of 0°C to +70°C. This component integrates phase-locked loop functionality to eliminate clock skew between input and output signals.

Feature Summary

• Zero-delay programmable PLL architecture for minimal clock skew
• 8:8 input-to-output buffering ratio with LVTTL outputs
• Supports frequencies up to 80 MHz on a 3.3V supply
• Available in 32-LCC (J-Lead) surface-mount package

Applications

• High-performance system clock distribution
• FPGA and ASIC clock synchronization
• Telecommunications equipment timing
• Industrial control systems requiring low jitter

Procurement Notes

Verify the specific suffix '2J' against official Infineon documentation to confirm pinout compatibility and electrical specifications relative to other variants in the CY7B991V family. Ensure the 32-LCC package dimensions match the target PCB footprint requirements before procurement.

Selection Notes

Select this component when an 8-channel LVTTL clock buffer with integrated PLL is required. Confirm that the 80 MHz maximum frequency meets system needs and that the 0°C to +70°C operating range is sufficient for the intended environment. Compare power consumption and jitter specifications against alternative clock drivers if strict low-power constraints exist.

Part Context

This part belongs to the RoboClock™ series of programmable clock generators and buffers. These devices are designed to replace multiple discrete logic components by integrating frequency synthesis and buffering capabilities into a single IC, reducing board space and design complexity.

Replacement Considerations

Check Infineon datasheets for direct pin-compatible replacements within the CY7B991V series. Verify if higher-frequency variants or different output voltage levels are available if system requirements change.
