CY7B994V-2BBXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY7B994V-2BBXC is a high-speed multi-phase PLL clock buffer from the RoboClock series by Cypress Semiconductor. It features a 1:18 fanout ratio, supporting up to 18 outputs with a maximum frequency of 200MHz. The device operates on a single 3.3V supply (2.97V to 3.63V) and accepts LVPECL or LVTTL inputs, producing LVTTL outputs. Packaged in a 100-TBGA (11x11) surface-mount case, it functions within a commercial temperature range of 0°C to 70°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component authenticity due to potential availability from secondary markets. Confirm package integrity and pin alignment upon receipt. Check for RoHS compliance status as older Cypress parts may not meet current environmental standards. Ensure storage conditions respect the MSL 3 rating to prevent moisture damage before reflow soldering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single differential or single-ended input requires expansion into 18 synchronized LVTTL outputs. It is suitable for designs needing precise phase control via internal PLL rather than simple passive buffering. Consider thermal dissipation requirements for the TBGA package in dense PCB layouts.
