CDC3S04YFFR

Overview

The Texas Instruments CDC3S04YFFR is a single-circuit clock fanout buffer designed for distributing high-frequency clock signals. It provides a 1:4 output ratio, supporting a maximum operating frequency of 52 MHz. The device operates within a supply voltage range of 1.65 V to 1.95 V and functions reliably across an ambient temperature range of -30°C to 85°C. Packaged in a compact 20-DSBGA (UFBGA) surface-mount case, it is intended for applications requiring low-power clock distribution with minimal footprint.

Feature Summary

• Single circuit configuration with 1:4 input-to-output fanout ratio
• Maximum operating frequency of 52 MHz
• Low-voltage operation supported by 1.65 V to 1.95 V supply range
• Compact 20-pin DSBGA package suitable for space-constrained designs

Applications

• Clock signal distribution in embedded systems
• Fanout buffering for microcontrollers and processors
• Low-power digital logic timing circuits

Procurement Notes

Verify the specific ordering suffix YFFR against official documentation to confirm packaging details such as tape and reel specifications or cut tape availability. Ensure the selected component matches the required 20-DSBGA package dimensions and lead-free manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a single-ended clock source requires expansion into four distinct outputs at frequencies up to 52 MHz. The narrow 1.65 V to 1.95 V supply requirement makes it suitable for low-voltage logic families. Confirm that the thermal performance within the -30°C to 85°C range aligns with the target application environment.

Part Context

This part belongs to the Texas Instruments family of clock buffers and drivers. It serves as a specialized solution for signal distribution where power consumption and physical size are critical constraints compared to standard logic gates or wider bus drivers.

Replacement Considerations

Consult manufacturer cross-reference tools for verified substitutes. Ensure any replacement maintains the 1:4 ratio, 52 MHz frequency limit, and compatible 1.65 V–1.95 V supply voltage requirements.
