CY29973AXI

CY29973AXI Description

The CY29973AXI is a highly versatile clock generator and support product designed by Infineon Technologies. This integrated circuit (IC) is specifically engineered for fanout distribution, multiplexing, spread spectrum clock generation, and zero-delay buffering. Housed in a 52-TQFP package, the CY29973AXI is suitable for surface-mount applications, making it ideal for compact and high-density PCB designs.

CY29973AXI Features

• DigiKey Programmable: The CY29973AXI is not verified for DigiKey programmability, ensuring that it maintains its factory-set configurations for consistent performance.
• Product Status: Although the CY29973AXI is marked as obsolete, it remains a reliable choice for legacy systems and applications where its specific features are required.
• PLL with Bypass: The inclusion of a Phase-Locked Loop (PLL) with bypass functionality allows for precise clock signal generation and the ability to bypass the PLL for direct input signal passing, enhancing flexibility.
• Input and Output Specifications: The IC accepts PECL (Positive Emitter-Coupled Logic) inputs and provides clock outputs, making it suitable for high-speed digital systems. It operates within a supply voltage range of 2.9V to 3.6V.
• Frequency Range: With a maximum frequency of 125MHz, the CY29973AXI can support a wide range of applications requiring high-frequency clock signals.
• Compliance and Standards: The CY29973AXI is REACH unaffected and RoHS3 compliant, ensuring it meets environmental and safety standards. It also has a Moisture Sensitivity Level (MSL) of 3, allowing for a 168-hour exposure before reflow soldering.
• Ratio and Differential Characteristics: The input-to-output ratio is 4:12, and it does not support differential signaling on either the input or output, simplifying design considerations.
• Additional Functionalities: The CY29973AXI includes a divider but does not feature a multiplier, making it suitable for applications requiring clock division.
• Packaging and Circuits: Available in a tray package, the CY29973AXI contains a single circuit, ensuring dedicated performance for each application.
