CDCLVC1103PW

Overview

The CDCLVC1103PW is a low-jitter, 1:3 LVCMOS fan-out clock buffer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports maximum input and output frequencies of 250 MHz. The device features a maximum propagation delay of 2 ns and draws approximately 10 mA of operating current. Packaged in an 8-TSSOP surface-mount case with a width of 4.40 mm, it is designed for applications requiring precise clock distribution. The component functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• 1:3 LVCMOS fan-out ratio with single circuit configuration
• Maximum operating frequency of 250 MHz for both input and output
• Low propagation delay of 2 ns maximum
• Supply voltage range of 2.3 V to 3.6 V

Applications

• General communication equipment clock distribution
• Industrial control system timing networks
• Consumer electronics requiring low jitter clock signals

Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the tube packaging format as indicated in the product parameters. Confirm that the 8-TSSOP package dimensions match the design footprint requirements. Ensure the supply voltage provided in the target application remains strictly within the 2.3 V to 3.6 V operational limits to maintain specified performance characteristics.

Selection Notes

Select this component when a 1:3 split is required for LVCMOS clock signals up to 250 MHz. Compare against other series members like CDCLVC1102 or CDCLVC1104 if different fan-out ratios are needed. Ensure the PCB layout accommodates the 8-TSSOP package size and that the thermal environment stays within the -40°C to +85°C operating range.

Part Context

This part belongs to the CDCLVC11xx family of modular, high-performance, low-skew universal clock buffers. The series utilizes LVCMOS technology and offers pin-to-pin compatibility across various fan-out configurations ranging from 1:2 to 1:12. This modularity allows designers to swap between different output counts without redesigning the board layout.

Replacement Considerations

Direct pin-compatible substitutes within the same family include CDCLVC1102 (1:2) and CDCLVC1104 (1:4). Verify that the alternative part's electrical specifications, particularly frequency and voltage ranges, meet the original design requirements.
