MAX3624A
The MAX3624A 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, Fibre Channel, SONET/SDH, and other networking applications. Maxim’s proprietary PLL design features ultra-low jitter (0.36psRMS) and excellent power-supply noise rejection, minimizing design risk for network equipment. The MAX3624A has three LVPECL outputs and one LVCMOS output. Selectable output dividers and a selectable feedback divider allow a range of output frequencies.
