The MEMS resonator offers better shock resistance (no quartz crystal to fracture) and faster start-up, but the output swing and jitter characteristics differ from quartz—verify the downstream receiver's input voltage threshold and jitter tolerance against the DSC1122 datasheet before committing a spin."},{"question":"Is DSC1122CE5-047.9990 RoHS compliant?","answer":"The evidence does not explicitly list RoHS status; however, Microchip's DSC1122 series is generally offered in RoHS-compliant terminations.
