CY2304ESXI-1

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2304ESXI-1 is a PLL-based clock driver from the Cypress 2304 series, designed for PCI-X and general-purpose buffering applications. It features four true outputs with no inverted outputs, operating within the CMOS logic family. The device is housed in an 8-pin SOIC package (PDSO8) with a lead-free construction compliant with MO-152 standards. It supports a standard input adjustment and provides three-state output characteristics. The component functions as a zero-delay buffer, locking to an input clock via an on-chip PLL to distribute high-speed signals with low skew.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific package variant (SOIC vs. TSSOP) and suffix codes against official Cypress documentation, as ordering information may vary by manufacturer revision. Confirm RoHS compliance status and lead-free designation through current datasheets or authorized distributor specifications before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a four-channel buffered clock solution is required for PCI-X interfaces or general digital logic. Ensure the design accommodates the 3.3V supply voltage typical of the 2304 series. Compare drive strength requirements against similar models like the CY2309 if more than four outputs are needed.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2304ESXI-1 belongs to the Cypress 2304 series of low-cost, 3.3V zero-delay buffers. It serves as a compact alternative to larger variants like the CY2309, offering four outputs in an 8-pin form factor. The series is characterized by its ability to lock to a reference input and provide synchronized outputs without added delay.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other members of the 2304 series such as the CY2304NZ or CY2304SI-1, provided pin compatibility and electrical parameters match. Cross-voltage or multi-output alternatives like the CY2309 series require schematic redesign due to package and pin count differences.
