Micro Networks has introduced a new clock generator designed for clock generation and distribution in optical networks including 10 G Ethernet fibercom systems and other applications requiring coherent frequency sources.

The new M250 Clock Generator provides synchronous output frequencies of 622.08 MHz, 311.04 MHz, and 155.52 MHz. Two output signals indicate "out of lock" and "loss of reference clock" conditions. The device operates with an input frequency of 19.44 MHz, and an internal reference clock, which can be activated by an "input mode select" control signal.
