CDC303NSR

Overview

The CDC303NSR is a clock buffer manufactured by Texas Instruments, belonging to the CDC303 series. It features one output and utilizes a SOIC-8 package for surface mount installation. The device supports a supply voltage range from 1.65 V to 3.45 V. Maximum propagation delay is specified at 200 ps, with a maximum input frequency of 200 MHz and a maximum output frequency of 200 MHz. Operating temperatures extend from -40 °C to +85 °C.

Feature Summary

• Provides single-output clock buffering capabilities
• Supports low-voltage operation down to 1.65 V
• Utilizes compact SOIC-8 surface-mount packaging

Applications

• Clock distribution in high-speed digital systems
• Signal buffering for data converters
• FPGA and ASIC clock management

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics. Ensure the component matches the required voltage and temperature specifications for the target application environment before integration.

Selection Notes

Select this component when a single buffered clock output is required within a low-voltage logic family. Confirm that the operating frequency does not exceed the 200 MHz limit and that the SOIC-8 footprint fits the board layout constraints.

Part Context

This part belongs to the CDC303 series of clock buffers from Texas Instruments. These devices are designed for general-purpose clock distribution applications requiring low skew and jitter performance in portable and battery-operated systems.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the same output configuration, voltage range, and package dimensions.
