CDCLVC1102PWR

Overview

The CDCLVC1102PWR is a low jitter, 1:2 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 propagation delay of up to 2 ns and utilizes LVCMOS logic levels for both input and output signals. Packaged in an 8-TSSOP surface-mount case with dimensions of 4.40 mm width, it is designed for applications requiring reliable clock distribution. The component functions as a single-circuit fanout buffer without differential signaling capabilities.

Feature Summary

• 1:2 LVCMOS fan-out ratio with 250 MHz maximum frequency
• Low propagation delay of 2 ns maximum
• Supply voltage range of 2.3 V to 3.6 V
• Available in 8-TSSOP package with Tape & Reel or Cut Tape options

Applications

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

Procurement Notes

Verify the specific packaging configuration required for production, as the CDCLVC1102PWR is available in both Tape & Reel (TR) and Cut Tape (CT) formats. Confirm that the 8-TSSOP footprint matches the PCB design constraints. Ensure the selected variant meets the -40°C to +85°C operating temperature range necessary for the intended environment. Cross-reference the manufacturer part number with distributor catalogs to ensure compatibility with existing inventory systems.

Selection Notes

Select this component when a single-input, dual-output LVCMOS clock buffer is required for frequencies up to 250 MHz. The 2.3 V to 3.6 V supply range accommodates standard 3.3 V and 2.5 V logic systems. Consider the 8-TSSOP package size for space-constrained surface-mount designs. Compare against other members of the CDCLVC11xx series if higher fan-out ratios such as 1:3 or 1:4 are needed instead.

Part Context

This device belongs to the CDCLVC11xx family of modular, high-performance, low-skew universal clock buffers from Texas Instruments. The series includes variants with different output counts, ranging from 1:2 to 1:12, all sharing pin-to-pin compatibility. This specific model represents the lowest fan-out option in the lineup, providing two outputs from a single LVCMOS input source.

Replacement Considerations

Pin-compatible alternatives within the same family include CDCLVC1103PW, CDCLVC1104PWR, and CDCLVC1106PWR. These parts offer higher output counts while maintaining identical electrical characteristics and package footprints. Verify that the increased drive capability of higher-count buffers does not exceed power budget constraints.
