CDC421156RGET [Texas Instruments]

The CDC421xxx is a fully integrated fixed frequency low-jitter clock generator. It incorporates a crystal oscillator circuitry with an integrated frequency synthesizer and a low-noise LC-based VCO operating from 1.75 GHz to 2.35 GHz. The device operates from a single 3.3V supply and is characterized for industrial temperature range from -40°C to 85°C. It provides differential LVPECL outputs with frequencies ranging from 100 MHz to 312.5 MHz, supported by input crystal frequencies of 31.25 MHz, 33.33 MHz, and 35.42 MHz. Key features include low output jitter (as low as 380 fs rms), low phase noise, and chip-enable control. The device is available in a QFN-24 package with ESD protection exceeding 2kV HBM.
