Texas Instruments CDC3RL02 Clock Fan-Out Buffer

Texas Instruments CDC3RL02 Dual-Channel Wave Clock Buffer that buffers a single master clock, such as a temperature-compensated crystal oscillator (TCXO) to multiple peripherals. The device has two clock request inputs, each of which enables a single clock output. The CDC3RL02 accepts square or sine waves at the master clock input, eliminating the need for an AC coupling capacitor. The smallest acceptable sine wave is a 0.3V signal (peak-to-peak). CDC3RL02 has been designed to offer minimal channel-to-channel skew, additive output jitter, and additive phase noise. The Texas Instruments CDC3RL02 is ideal for use in portable end-equipment, such as mobile phones, that require clock buffering with minimal additive phase noise and fan-out capabilities.
