CDCLVC1104PWR

Overview

The CDCLVC1104PWR 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 high-performance timing applications, it provides four outputs from a single LVCMOS input, ensuring signal integrity across industrial temperature ranges from -40°C to +85°C.

Feature Summary

• 1:4 LVCMOS fan-out configuration with single-ended input and outputs
• Maximum operating frequency of 250 MHz with 2 ns max propagation delay
• 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 requiring low-jitter clock buffering

Procurement Notes

Verify the specific packaging option (Tape & Reel vs. Cut Tape) required for the order, as the part number suffix 'R' typically indicates reel packaging. Confirm that the 8-TSSOP footprint matches the PCB design constraints. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range and 2.3 V to 3.6 V supply voltage limits for reliable operation.

Selection Notes

Select this component when a 1:4 split ratio is needed for LVCMOS signals up to 250 MHz. Compare against other members of the CDCLVC11xx series if different fan-out ratios (e.g., 1:2, 1:3, 1:8) are required, as they share similar electrical characteristics and pinout compatibility. Ensure the power supply can maintain stability within the 2.3 V to 3.6 V window to meet jitter specifications.

Part Context

This device belongs to the CDCLVC11xx family of modular, low-skew clock buffers. The family includes variants such as CDCLVC1102, CDCLVC1103, and CDCLVC1108, offering fan-out ratios from 1:2 to 1:12. All devices in this series feature compatible pinouts, facilitating easy upgrades or redesigns without altering the board layout significantly.

Replacement Considerations

Direct replacements within the same family include CDCLVC1102PW (1:2), CDCLVC1103PW (1:3), and CDCLVC1108PW (1:8). These parts share identical electrical parameters and pin configurations, allowing for drop-in substitution if the fan-out requirement changes.
