MAX3679A +3.3V, Low-Jitter Crystal to LVPECL Clock Generator
The MAX3679A is a low-jitter precision clock generator with the integration of three LVPECL and one LVCMOS outputs optimized for Ethernet applications.The device integrates a crystal oscillator and a phase-locked loop (PLL)clock multiplier to generate high-frequency clock outputs for Ethernet applications. This proprietary PLL design features ultra-low jitter (0.36psRMS)and excellent power-supply noise rejection, minimizing design risk for network equipment.
