LMK3C0105TV1RGTRQ1-Texas Instruments-Price, Stock & Datasheet

The LMK3C0105-Q1 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 REF_CTRL 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 Recommendations for detailed guidelines on power supply filtering and sourcing from a DC/DC supply.
