CY7B991V-5JXCT

Overview

The CY7B991V-5JXCT is a low voltage programmable skew clock buffer from the RoboClock series. It operates with a maximum frequency of 80 MHz and supports an 8:8 input-to-output ratio. The device features LVTTL outputs and accepts 3-State inputs, powered by a supply voltage range of 2.97V to 3.63V. Packaged in a 32-LCC (J-Lead) surface mount case, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• RoboClock series low voltage programmable skew clock buffer
• 8:8 input-to-output fanout ratio with LVTTL outputs
• Maximum operating frequency of 80 MHz
• Supply voltage range of 2.97V to 3.63V

Applications

• System clock distribution networks
• High-speed digital logic synchronization
• Programmable skew adjustment for timing-critical paths

Procurement Notes

Verify the specific ordering suffix 'T' against official Cypress documentation to confirm tape-and-reel packaging status, as local data indicates bulk packaging. Ensure compatibility with 32-LCC J-Lead footprint requirements during procurement planning.

Selection Notes

Select this component when an 8-channel LVTTL fanout buffer with programmable skew capabilities is required. Confirm that the 80 MHz frequency limit meets system timing needs and that the 2.97V to 3.63V supply range aligns with the target power architecture.

Part Context

This part belongs to the RoboClock family of clock buffers designed for low voltage applications. It provides precise clock distribution with programmable skew control, distinguishing it from standard fixed-delay buffers in high-performance digital systems.

Replacement Considerations

Consult official replacement guides for direct equivalents. Verify pinout and electrical specifications before substituting with other clock buffer ICs.
