The CY2309CSXC from Cypress Semiconductor is a high-performance, low-jitter zero delay buffer (ZDB) designed for clock distribution in various applications. This device multiplies a reference clock input to provide multiple output clocks with minimal skew and jitter, making it ideal for use in high-speed digital systems where precise timing is critical.

Applications

• Clock distribution in motherboards
• Networking equipment
• Servers and workstations
• High-speed digital circuits
• Graphics cards

Features

• Zero delay buffer architecture
• Supports up to 9 output clocks
• Low output skew (< 50 ps)
• Low additive jitter (< 100 fs RMS)
• Operates from a 3.3V power supply
• Pin-compatible with industry-standard devices
• Available in TSSOP and SOIC packages
• Output enable control

Benefits

• Minimizes clock skew, ensuring reliable data transfer
• Reduces jitter, improving signal integrity
• Simplifies clock distribution design
• Enhances system performance by providing clean and stable clock signals
• Reduces BOM cost by integrating multiple clock buffers into a single chip

Additional Details

The CY2309CSXC features a phase-locked loop (PLL) that synchronizes the output clocks to the input reference clock. It supports a wide range of input frequencies and can be configured to multiply or divide the input clock frequency. The device also includes an output enable control pin, which allows the outputs to be disabled for power saving or testing purposes. The low skew and jitter performance of the CY2309CSXC makes it a popular choice for high-performance clock distribution applications, ensuring reliable and stable operation of digital systems. The device is available in both TSSOP and SOIC packages, offering flexibility in PCB layout and design.
