The LVDS output provides low-jitter differential signaling with typical 350 mV swing, reducing electromagnetic interference compared to single-ended CMOS clocks at this frequency.
Active supply current is 32 mA max at 300 MHz, typical for a high-frequency LVDS oscillator.
The supply voltage range of 2.25V to 3.63V covers common 2.5V and 3.3V rails, simplifying power tree design without needing a dedicated regulator for the oscillator.
The standby function disables the output and reduces supply current to 95 µA max. The oscillator stops oscillating; the output enters a high-impedance state. A logic-low on the standby pin enables normal operation.
Yes, if the board is designed for a 6-SMD, no-lead exposed pad package and accepts LVDS input. The MEMS resonator is more shock and vibration tolerant than quartz, but the ±50 ppm stability is comparable to a standard quartz XO. Confirm the supply voltage and output logic compatibility.
The part is listed as RoHS compliant per Microchip's standard offering. The 6-SMD package is lead-free and compatible with RoHS assembly processes.
