CDCLVC1112PW

Overview

The CDCLVC1112PW is a low-jitter LVCMOS fan-out clock buffer manufactured by Texas Instruments. It features a single input and twelve outputs, supporting maximum frequencies of 250 MHz for both input and output signals. The device operates within a supply voltage range of 2.3 V to 3.6 V and exhibits a maximum propagation delay of 2 ns. Designed for surface-mount assembly, it is housed in a 24-TSSOP package with a width of 4.40 mm. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• 1:12 LVCMOS fan-out ratio with 250 MHz maximum frequency
• Low jitter performance with 2 ns maximum propagation delay
• Operates on 2.3 V to 3.6 V supply voltage
• Available in 24-TSSOP surface-mount package

Applications

• Clock distribution networks requiring high fan-out
• Low jitter signal buffering in digital systems
• LVCMOS interface timing management

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. The PW suffix indicates tube packaging, which differs from reel or cut tape options available in the same series. Confirm RoHS compliance status through official datasheets before procurement integration.

Selection Notes

Select this component when a single clock source must drive up to twelve LVCMOS loads simultaneously. Ensure the system power supply remains within the 2.3 V to 3.6 V operational window. Verify that the 24-TSSOP footprint aligns with the PCB layout constraints and thermal requirements for the target application environment.

Part Context

This part belongs to the CDCLVC11xx family of low-jitter clock buffers. Variants such as CDCLVC1102, CDCLVC1104, and CDCLVC1108 offer different output ratios (1:2, 1:4, 1:8) while maintaining similar electrical characteristics and operating conditions. The CDCLVC1112 provides the highest fan-out capability within this specific subset of the series.

Replacement Considerations

Direct substitutes include other members of the CDCLVC11xx series with lower output counts, such as CDCLVC1108PW or CDCLVC1104PW, if fewer outputs are sufficient. Cross-referencing pinouts and electrical specifications is required when considering alternative manufacturers.
