CY2304SXI-2

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2304SXI-2 is a 3.3 V zero delay buffer featuring an on-chip phase-locked loop (PLL) designed for high-speed clock distribution in PC, workstation, datacom, and telecom applications. It operates within a frequency range of 10 MHz to 133 MHz and provides four true outputs across two banks. The device guarantees input-to-output skew of less than 250 ps and output-to-output skew of less than 200 ps. It supports industrial temperature operation from -40 °C to +85 °C with a supply voltage range of 3.0 V to 3.6 V.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero input-output propagation delay adjustable by capacitive load on the FBK pin
• Configurable output frequencies: Reference/2 or 2x Reference depending on feedback connection
• Low-skew performance with typical peak cycle-to-cycle jitter of 90 ps at 66 MHz
• Power-down mode draws less than 25 μA when no rising edges are present on the REF input

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC and workstation clock distribution
• Datacom and telecom systems
• High-performance computing applications

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40 °C to +85 °C). Confirm the '-2' suffix indicates the specific configuration allowing Reference/2 or 2x Reference frequencies. Ensure the package type matches the required 8-pin SOIC form factor.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2304SXI-2 when system requirements demand configurable output frequencies relative to the reference clock, specifically needing half or double the reference rate. This variant is suitable for designs requiring low skew and jitter performance in industrial environments. Verify that the load capacitance requirements align with the specified 15 pF or 30 pF limits based on the operating frequency.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2304 series includes variants such as the CY2304SXI-1, which provides only the reference frequency on all outputs. The CY2304SXI-2 differs by enabling frequency division or multiplication through the feedback path selection. Both share the same 8-pin SOIC package and core PLL architecture but offer different output flexibility.
