This capability eliminates the need for an expensive high-frequency oscillator and a fanout buffer, thus saving board space and cost. The MAX3671 is ideal for Ethernet interface applications such as enterprise switches and routers, and the MAX3673 is well suited for wireless base stations that require CPRI reference clocking.
The MAX3671/MAX3673 are fully specified over the -45 degrees Celsius to +85 degrees Celsius extended temperature range, and operate from 3.3V ±5%. They are available in a lead-free, 56-pin TQFN package. Prices start at $10.26 (1000-up, FOB USA). Evaluation kits are available to speed designs.
