CDCLVC1108PW

Overview

The CDCLVC1108PW is a low jitter, 1:8 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 consumes approximately 10 mA of operating current. Packaged in a 16-TSSOP surface-mount case with a width of 4.40 mm, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• 1:8 LVCMOS fan-out ratio for single-input to eight-output distribution
• Low additive jitter performance suitable for high-speed clocking
• Asynchronous output enable control (1G) for power management
• Pin-compatible with other members of the CDCLVC11xx family

Applications

• Multi-clock domain distribution in communication systems
• Backplane clock driving for industrial equipment
• FPGA and CPU clock tree optimization in consumer electronics

Procurement Notes

Verify the package type matches the required 16-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 for the target environment.

Selection Notes

Select this component when an 8-channel LVCMOS clock distribution is required. Compare against other CDCLVC11xx variants if different fan-out ratios such as 1:2 or 1:6 are needed. Ensure the PCB layout allows for proper decoupling near the power pins to maintain signal integrity at 250 MHz.

Part Context

This part belongs to the CDCLVC11xx modular clock buffer series from Texas Instruments. The family includes variants with 1:2 through 1:12 outputs, all sharing pin compatibility and core electrical characteristics. This specific model provides the 1:8 configuration within the standard TSSOP packaging options available for the series.

Replacement Considerations

Other models in the CDCLVC11xx series, such as CDCLVC1102, CDCLVC1103, CDCLVC1104, CDCLVC1106, CDCLVC1110, and CDCLVC1112, are pin-compatible alternatives offering different output counts.
