Clock Generator – generates fifteen buffered LVTTL outputs

Maxim introduced the MAX9489 , a clock generator that addresses the timing requirements for network/edge routers, telecom/networking equipment and data-storage systems. It features multi-output capability, high performance, low jitter, and low output-to-output skew.

The MAX9489 generates fifteen buffered LVTTL outputs with independent frequency selections. Through an integrated I2C interface, each output can be set to any of the ten independent, selectable frequencies of 133MHz, 125MHz, 100MHz, 83MHz, 80MHz, 66MHz, 62.5MHz, 50MHz, 33MHz and 25MHz. To perform system overdrive and underdrive testing, the device also offers a selectable output-frequency margin of ±5% to ±10%.

The MAX9489 operates from a 3.3V single supply and a 25MHz crystal or reference clock. The device is offered in a small-footprint, 5 x 5mm 32-pin QFN package, and operates over the extended temperature range (-40&degC to +85&degC). Prices start at $6.77 (1000-up, FOB USA).
