CY2304SI-1

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2304SI-1 is a 3.3V zero delay buffer manufactured by Cypress Semiconductor, now part of Infineon Technologies. It operates within an industrial temperature range of -40°C to 85°C and supports frequencies from 10 MHz to 133 MHz with a 15 pF load. The device features an on-chip PLL that locks to the REF input, ensuring input-to-output skew remains below 250 ps and output-to-output skew stays under 200 ps. Typical peak cycle-to-cycle jitter is 90 ps at 66 MHz with a 15 pF load. It utilizes an 8-pin 150-mil SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero input-output propagation delay adjustable via capacitive loading on the FBK pin
• Internal phase-locked loop (PLL) for high-speed clock distribution
• Low-skew outputs with guaranteed timing performance across banks

Clock Generators, PLLs, Frequency Synthesizers Applications

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin as Cypress Semiconductor, which was acquired by Infineon Technologies. Confirm the specific suffix 'SI' indicates the industrial temperature grade (-40°C to 85°C). Ensure the '-1' designation matches the required reference frequency configuration without internal division.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low skew and zero delay are critical for distributing high-speed clocks in industrial environments. Compare against commercial variants if operating temperatures exceed 85°C. Verify that the 150-mil SOIC package dimensions fit the target PCB layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY2304 family of zero delay buffers designed for precise clock management. It is distinct from other series like the CY2308 due to its specific four-output configuration and single-reference architecture tailored for compact system designs.
