CY2308SXC-2T

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2308SXC-2T is a commercial temperature range, 3.3 V Zero Delay Buffer manufactured by Infineon Technologies (formerly Cypress). It operates within an input frequency range of 10 MHz to 133.3 MHz and provides eight outputs divided into two banks. This specific variant enables users to obtain 2x and 1x frequencies on each output bank depending on the feedback pin selection. The device features adjustable zero input-output propagation delay via capacitive load on the FBK input, with typical cycle-to-cycle jitter of 75 ps at 66 MHz and 15 pF load. It utilizes a 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the component status as this part number may be subject to discontinuation or obsolescence notices. Confirm the exact ordering suffix matches the required package type and temperature range specifications before procurement. Cross-reference the datasheet revision for any errata updates affecting performance parameters.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2308SXC-2T when a 2x frequency multiplier is required on one bank while maintaining a 1x reference frequency on the other bank. Ensure the application supports the necessary feedback configuration to achieve the desired frequency multiplication. Verify that the 3.3 V supply voltage and commercial temperature range meet system requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2308 series comprises multiple configurations including -1, -2, -3, -4, and -5H variants. The -2 variant specifically allows for mixed frequency outputs. Other variants offer different multiplication factors such as 4x/2x or uniform 2x outputs across all banks. The SXC suffix denotes the commercial temperature range and SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include CY2308SXI-2T for industrial temperature range applications. For TSSOP packages, consider CY2308ZXC-2T. Higher drive versions like CY2308SXC-1HT are available but do not provide the same 2x/1x frequency configuration.
