MAX3674ECM+T

The MAX3674 is a high-performance network clock synthesizer IC for networking, computing, and telecom applications. It integrates a crystal oscillator, a lownoise phase-locked loop (PLL), programmable dividers, and high-frequency LVPECL output buffers.
The PLL generates a high-frequency clock based on a low-frequency reference clock provided by the on-chip crystal oscillator or an external LVCMOS clock.
The MAX3674 has excellent period jitter, cycle-to-cycle jitter, and supply noise rejection performance. With output frequencies programmable from 21.25MHz to 1360MHz and support of two differential PECL output signals, the device provides a versatile solution for the most demanding clock applications.
