CY2304SC-1

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2304SC-1 is a 3.3V zero delay buffer manufactured by Cypress Semiconductor Corp, designed for distributing high-speed clocks in PC, workstation, datacom, and telecom applications. It features an on-chip phase-locked loop (PLL) that locks to an input clock presented on the REF pin. The device operates within a frequency range of 10 MHz to 133 MHz and provides four low-skew outputs organized into two banks. It is housed in a space-saving 8-pin 150-mil SOIC package suitable for commercial temperature environments ranging from 0°C to 70°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero input-output propagation delay adjustable via capacitive load on the FBK input
• On-chip PLL with guaranteed input-to-output skew less than 250 ps
• Four low-skew outputs divided into two banks with output-to-output skew under 200 ps
• Power down mode draws less than 25 μA when no rising edges are present on the REF input

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and temperature rating. The CY2304SC-1 denotes the commercial temperature variant in an 8-pin SOIC package. Confirm RoHS compliance status as legacy parts may have non-compliant variants. Ensure the design accounts for the manufacturer's note indicating this series is not recommended for new designs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2304SC-1 for commercial temperature applications requiring a 3.3V supply between 3.0V and 3.6V. Choose this part over industrial variants if the operating ambient temperature remains within 0°C to 70°C. Consider the CY2304SI-1 if operation below 0°C or above 70°C is required. Verify that the system load capacitance aligns with the specified limits of 15 pF for frequencies above 100 MHz.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2304SC-1 belongs to the CY2304 family of 3.3V zero delay buffers produced by Cypress Semiconductor Corporation. This family includes variants such as the CY2304SC-2 which supports different frequency configurations. The component is documented under specification number 38-07247 Rev. *E. Cypress Semiconductor was acquired by Infineon Technologies, though the original manufacturer designation remains relevant for historical datasheet references.
