CDCL1810ARGZR

Overview

The CDCL1810ARGZR is a high-performance clock distribution buffer manufactured by Texas Instruments. It features one differential LVDS input and ten differential CML outputs, supporting frequencies up to 650 MHz. The device operates on a single 1.8V supply (1.7V–1.9V) within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include low input-to-output added jitter of 10fs RMS typical and a maximum propagation delay of 2.3ns. It utilizes a 48-pin VQFN package with an exposed pad for thermal management.

Feature Summary

• Low Jitter Performance: Achieves as low as 10fs RMS input-to-output added jitter.
• Flexible Frequency Division: Supports programmable divide ratios of 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, and 80 via two independent dividers.
• Phase Adjustment: Allows phase adjustment between output groups using an SDA/SCL serial interface.
• Integrated Termination: Features 100Ω differential on-chip termination for the LVDS input and 50Ω single-ended on-chip termination for CML outputs.

Applications

• High-speed data converter clocking
• FPGA and ASIC clock distribution
• Telecommunications infrastructure timing
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix ARgzR against the manufacturer's official documentation to confirm tape and reel packaging details and lead time requirements. Ensure the design supports the 1.8V supply voltage and LVDS/CML signal levels. Confirm that the 48-VQFN footprint matches the PCB layout specifications provided in the datasheet.

Selection Notes

Select this component when low jitter performance and flexible frequency division are required for clock distribution networks. The CDCL1810 is suitable for applications needing a single LVDS source to drive multiple CML loads. Consider the 48-pin VQFN package size and the need for serial programming capabilities via I2C-compatible interfaces during system integration.

Part Context

The CDCL1810 belongs to the family of high-performance clock buffers and drivers from Texas Instruments. It is designed to provide precise timing signals with minimal noise addition. The ARGZR variant specifically denotes the automotive-grade or industrial-grade version packaged in a tape and reel format for automated assembly processes.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified pin-to-pin compatible alternatives. Ensure any substitute part maintains the 650 MHz frequency capability, 1.8V operating voltage, and 48-VQFN package dimensions.
