Dual-frequency MEMS oscillator, 4-VFLGA, now obsolete
The DSC6023HI2A-00AD: Microchip lists this part as obsolete, so new designs should not target this order code.
MEMS resonator vs quartz – what it means for your board
The trade-off is that the phase-noise floor is higher than a good quartz oscillator, but for 6 MHz CMOS clocks the jitter contribution is usually below what a digital input stage can resolve.
