CDCLVC1102PW

Overview

The CDCLVC1102PW 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 maximum propagation delay of 2 ns and draws approximately 6 mA of operating current. Packaged in an 8-TSSOP surface-mount case with a width of 4.40 mm, it functions across an extended temperature range from -40°C to +85°C.

Feature Summary

• 1:2 LVCMOS fan-out ratio for clock distribution
• Maximum operating frequency of 250 MHz
• Low propagation delay of 2 ns (maximum)
• Supply voltage range of 2.3 V to 3.6 V

Applications

• General communication equipment
• Industrial applications
• Consumer electronics

Procurement Notes

Verify the package type matches the required 8-TSSOP form factor. Confirm that the supply voltage requirements align with the 2.3 V to 3.6 V operational range. Ensure the design accommodates the specified -40°C to +85°C temperature limits. Check for RoHS compliance status if environmental regulations apply to the target assembly.

Selection Notes

Select this component when a single LVCMOS clock signal requires splitting into two buffered outputs. The 1:2 ratio distinguishes it from other variants like the CDCLVC1103 or CDCLVC1104. Ensure the PCB layout supports the TSSOP-8 footprint dimensions. Verify that the system power supply remains stable within the 2.3 V to 3.6 V window during operation.

Part Context

This part belongs to the CDCLVC11xx series of modular, high-performance, low-skew universal clock buffers. The series utilizes LVCMOS technology and offers pin-to-pin compatibility across different fan-out ratios, including 1:3, 1:4, 1:6, 1:8, 1:10, and 1:12 variants. This modularity facilitates easier replacement and design scaling within clock distribution networks.

Replacement Considerations

Compatible substitutes include CDCLVC1103PW, CDCLVC1104PW, CDCLVC1106PW, and CDCLVC1108PW. These parts share identical pinouts and electrical characteristics but offer higher output counts. Ensure the additional outputs are not utilized or are properly terminated if substituted.
