CY7B991V-7JXC

Overview

The CY7B991V-7JXC is a zero-delay programmable PLL clock buffer from the RoboClock series by Infineon Technologies. It operates with a single circuit and provides an 8:8 input-to-output ratio. The device supports a maximum frequency of 80 MHz, with an operating supply voltage range of 2.97 V to 3.63 V. It features LVTTL output levels and is housed in a 32-PLCC package (32-LCC J-Lead). Designed for surface mount installation, it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Zero-delay programmable PLL architecture
• 8:8 input-to-output clock buffering ratio
• Maximum operating frequency of 80 MHz
• LVTTL output signal levels

Applications

• High-speed digital system clock distribution
• Programmable clock generation for logic circuits
• Low-jitter clock buffering in embedded systems

Procurement Notes

Verify the specific suffix 'V' against official documentation to confirm voltage or package variations, as standard listings may differ. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the 32-PLCC footprint matches the target PCB design constraints.

Selection Notes

Select this component when an 8-channel LVTTL clock buffer with zero-delay characteristics is required. Ensure the system power supply remains within the 2.97 V to 3.63 V range. Verify that the 80 MHz maximum frequency meets the application's timing requirements and that the 32-PLCC package is compatible with the assembly process.

Part Context

This part belongs to the RoboClock series, which specializes in programmable clock management solutions. The CY7B991 variant specifically addresses applications requiring precise clock skew control and fan-out capabilities for multiple synchronous devices within a single circuit configuration.

Replacement Considerations

Check for direct pin-compatible substitutes within the same RoboClock family. Verify if alternative packages or updated suffixes offer equivalent electrical specifications for existing designs.
