ADVANCE INFORMATION
The LMK3H0102 is a reference-less clock generator with an integrated BAW oscillator. The BAW frequency, nominally 2467 MHz, is divided down by two fractional output dividers (FODs), each of which is capable of generating frequencies between 100 MHz and 400 MHz. Each FOD can be routed to one of two channel dividers, which divides the FOD frequency down to generate frequencies from 2.5 MHz to 200 MHz. For generating frequencies above 200 MHz, both FODs can be routed to the edge combiner, which combines the uses both FODs to make sure that the output clock maintains a 50% duty cycle. An additional LVCMOS clock, with a voltage corresponding with VDD, can be configured using the REF_CTRL pin. By default, this pin is configured as a CLK_READY signal, which is high when the output clocks are active.
