CDCLVC1104PW

Overview

The CDCLVC1104PW is a low jitter, 1:4 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 utilizes an 8-TSSOP surface-mount package. Designed for robust performance, it functions across an operating temperature range from -40°C to +85°C. This component serves as a modular solution for distributing clock signals in digital systems requiring precise timing distribution.

Feature Summary

• 1:4 LVCMOS fan-out ratio with single circuit configuration
• Maximum operating frequency of 250 MHz for both input and output
• Low propagation delay with a maximum specification of 2 ns
• Available in an 8-TSSOP tube-packaged surface-mount format

Applications

• General communication equipment clock distribution
• Industrial control system timing networks
• Consumer electronics signal buffering

Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the tube packaging variant rather than the 'PWR' reel variant. Confirm that the 8-TSSOP footprint matches the target PCB design constraints. Ensure the 2.3 V to 3.6 V supply voltage requirements align with the system power rails before integration.

Selection Notes

Select this model when a 1:4 split is required for LVCMOS signals up to 250 MHz. Compare against other series members like CDCLVC1102 or CDCLVC1103 if different fan-out ratios are needed. Verify that the 2 ns propagation delay meets the system's timing budget. Ensure the TSSOP-8 package dimensions fit the available board space.

Part Context

This component belongs to the CDCLVC11xx family of modular, low-skew clock buffers. The series includes variants with fan-out ratios ranging from 1:2 to 1:12. All devices in this family share pin compatibility and similar electrical characteristics, facilitating easy substitution between different split ratios within the same design architecture.

Replacement Considerations

Direct pin-compatible substitutes include CDCLVC1102PWR (1:2), CDCLVC1103PWR (1:3), CDCLVC1106PWR (1:6), and CDCLVC1108PWR (1:8). Note that these alternatives may have different packaging options such as reels versus tubes.
