CY7B9910-7SXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY7B9910-7SXC is a low skew clock buffer manufactured by Cypress Semiconductor Corp. It operates within a frequency range of 15 to 80 MHz and features zero input-to-output delay with 50% duty cycle outputs. The device provides eight individual drivers capable of driving terminated transmission lines with impedances as low as 50Ω. It utilizes an integrated Phase Locked Loop (PLL) for synchronization, achieving output skew typically less than 300 ps and up to 750 ps maximum. Jitter specifications are under 200 ps peak-to-peak and 25 ps RMS. The component is housed in a 24-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'X' against official documentation to confirm lead-free status and commercial operating temperature range. Confirm package dimensions match the 24-pin SOIC specification. Ensure compatibility with TTL logic levels required by the CY7B9910 variant.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when zero delay and minimal skew are critical for multi-point clock distribution. Compare the 750 ps maximum skew against tighter requirements offered by -2 or -5 variants. Verify that the 5V supply voltage aligns with the system design constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY7B9910/CY7B9920 family of low skew clock buffers. The CY7B9910 variant specifically delivers full swing TTL logic levels, distinguishing it from the CMOS output CY7B9920. Both share identical pinouts and functional descriptions.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

CY7B9910-2SXC offers lower skew specifications. CY7B9910-5SXC provides intermediate skew performance. CY7B9920-7SXC is functionally equivalent but uses CMOS outputs instead of TTL.
