Maxim Integrated Products released a clock generator that claims to address the timing requirements for network/edge routers, telecom/networking equipment and data storage systems.

Featuring multioutput capability, high performance, low jitter and low output-to-output skew, the MAX9489 generates 15 buffered LVTTL outputs with independent frequency selections. Through an integrated I?C interface, each output can be set to any of the ten independent, selectable frequencies of 133-, 125-, 100-, 83-, 80-, 66-, 62.5-, 50-, 33- and 25MHz. And to perform system overdrive and underdrive testing, the device also offers a selectable output-frequency margin of 5 percent to 10 percent.

The new clock generator operates from a 3.3V single supply and a 25MHz crystal or reference clock. It is offered in a small-footprint, 5-by-5mm 32-pin QFN package, and operates over the extended temperature range (-40C to 85C). Prices start at $6.77 (1,000-up, FOB USA).
