Low-Jitter, Precision Clock Generator with Two Outputs
General Description
The MAX3622 is a low-jitter precision clock generator optimized for networking applications. The device integrates a crystal oscillator and a phase-locked loop (PLL) clock multiplier to generate high-frequency clock outputs for Ethernet and other networking applications. The proprietary PLL design features ultra-low jitter (0.36psRMS) and excellent power-supply noise rejection, minimizing design risk for network equipment. The MAX3622 has one LVPECL output and one LVCMOS output. It is available in a 16-pin TSSOP package and operates over the 0°C to +70°C temperature range.
