The 312.5 MHz rate aligns with the standard 156.25 MHz × 2 multiplier used in many networking PHY and MAC devices, so it directly clocks the PLL reference input without an external frequency doubler. ## Supply and temperature margins for the timing tree The 162 mA supply current is the peak draw at 312.5 MHz; budget this into the 3.3 V rail capacity, especially if multiple oscillators share the same regulator.","metaTitle":"TI LMK61E2-312M50SIAR Clock Oscillator, 312.5 MHz, Active","metaDescription":"Texas Instruments LMK61E2-312M50SIAR clock oscillator, 312.5 MHz, -40°C to 85°C, 6-QFM package.
