Overview

The CDCLVC1104PWR is a high-performance, low-additive-jitter 1:4 LVCMOS fanout buffer designed for clock distribution in high-speed digital systems. It operates across a wide voltage range of 2.3V to 3.6V and supports frequencies up to 250 MHz. This device is optimized for maintaining signal integrity by providing exceptionally low pin-to-pin skew of less than 50 ps.

Why Choose This Part

The CDCLVC1104PWR offers ultra-low additive jitter of less than 100 fs, ensuring minimal phase noise introduction into the clock path. Its small 8-TSSOP footprint and low static current consumption of 60 uA make it suitable for space-constrained and power-sensitive designs.

Applications

High-Speed Clock Distribution
Distributing a single reference clock to up to four synchronized components such as FPGAs, processors, or ADCs.
Signal Integrity Maintenance
Used as a buffer to refresh LVCMOS signals across long PCB traces to prevent rise-time degradation.
System Clock Expansion
Increasing the fanout capability of low-power oscillators that cannot drive multiple high-capacitance loads directly.

Getting Started

When designing with this buffer, place a 0.1 uF decoupling capacitor as close to the VDD pin as possible to minimize power supply noise. Ensure the input signal is a clean LVCMOS level within the 2.3V to 3.6V range and use series termination resistors at the outputs to match PCB trace impedance.
