MAX3625B: Precision timing for high-speed data communications

Its -57dBc PSNR minimizes jitter degradation and eases design in noisy system environments. The MAX3625B eliminates the expensive crystal oscillator and fanout buffer required by conventional solutions, as it only requires an external, AT-cut fundamental-mode crystal. Because it reduces the space requirements and cost of the total clock-distribution solution, this device is well suited for applications such as Ethernet switches/routers and storage-area network switches.

To further reduce the overall BOM, the MAX3625B provides three LVPECL outputs up to 320MHz from two output-divider banks. The output dividers are programmable, allowing designers to set these outputs to the frequencies required by their application.

The MAX3625B operates from 3.3V ±5% and is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. It is available in a small, 7.8mm x 4.4mm, lead-free, 24-pin TSSOP package. Prices start at $7.35 (1000-up, FOB USA).
