5 output reference-less clock generator with bulk acoustic wave (BAW)

The LMK3C0105 is a 5-output reference-less clock generator with SSC support.

The device is based on TI proprietary Bulk Acoustic Wave (BAW) technology and

provides ±25ppm clock outputs without any crystal or external clock reference. The

device can provide 5 SSC clocks, 5 non-SSC clocks, or a mix of SSC and non-SSC

clocks at the same time. Up to three different output frequencies can be generated

across the five outputs. Each output channel can select either FOD as the frequency

source to generate four LVCMOS clocks; the REFCTRL pin functions as a fifth LVCMOS

clock output, and can select either FOD as the source.

The device can be easily configured

through either pins or the I2C interface. An external DC/DC can be used

to power the device. Refer to Power Supply
