MAX3629CTJ+

The MAX3629 is a low-jitter precision clock generator optimized for network applications.
The device integrates a crystal oscillator and a phase-locked loop (PLL) to generate high-frequency clock outputs for Ethernet applications.Maxim’s proprietary PLL design features ultra-low jitter (0.4psRMS) and excellent power-supply noise rejection (PSNR), minimizing design risk for network equipment.
The MAX3629 contains five LVDS outputs and three LVCMOS outputs.
The output frequencies are selectable among 125MHz, 156.25MHz, and 312.5MHz by pin control.
