What the 1 GHz ceiling and 162 mA supply mean for your clock tree
The LMK61E07-SIAT is a PLLatinum™ family clock oscillator that outputs a fixed frequency at 400 MHz, 900 MHz, or 1 GHz — the specific frequency is factory-programmed per the order code variant, so the SIAT suffix identifies the exact frequency option on your BOM line. The 162 mA supply current at 3.135 V to 3.465 V is the total device draw including the internal PLL and output buffer; budget this into your 3.3 V rail capacity.
