CY7B9910-2SXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY7B9910-2SXC is a low skew clock buffer manufactured by Cypress Semiconductor, now part of Infineon Technologies. It features an integrated PLL for zero-delay clock distribution with eight outputs capable of driving terminated transmission lines down to 50Ω. The device operates within a frequency range of 15 MHz to 80 MHz and provides TTL logic levels. Key electrical specifications include typical output skew under 100 ps, peak-to-peak jitter below 200 ps, and RMS jitter below 25 ps. It utilizes a 24-pin SOIC package and requires a 5V ± 10% supply voltage.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the component status carefully, as the datasheet explicitly notes that this Pb-free device is not recommended for new designs. Confirm the specific accuracy grade (250 ps) associated with the -2 suffix during sourcing. Ensure compatibility with existing commercial temperature range requirements (-0°C to +70°C) before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY7B9910-2SXC when TTL logic level outputs are required for clock distribution. Compare against the CY7B9920 series if CMOS levels are needed instead. Consider the -5 or -7 variants if higher skew tolerances are acceptable for cost reduction. Verify that the operating frequency falls within the 15 MHz to 80 MHz range supported by the FS pin configuration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY7B9910/CY7B9920 family of low skew clock buffers originally developed by Cypress Semiconductor. These devices were designed to optimize timing in high-performance computer systems by providing multiple output clock drivers with minimal skew. The product line has been integrated into the Infineon portfolio following corporate acquisition.
