The LVDS differential pair gives clean edge rates into 100-ohm terminated traces, reducing jitter compared to a single-ended CMOS oscillator at this frequency. Supply voltage spans 2.25V to 3.63V, so it runs directly off a 2.5V or 3.3V rail without a local LDO. ## Active production — no quartz lead-time risk The MEMS resonator is sourced from Microchip's internal fab, not a quartz blank supplier, so the part avoids the extended lead times that quartz oscillators have seen in recent shortages. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm.","metaTitle":"DSC1123AE1-148.5000T – Microchip MEMS XO, 148.5 MHz LVDS","metaDescription":"DSC1123AE1-148.5000T – Microchip DSC1123 series MEMS oscillator, 148.5 MHz LVDS output, 2.25V-3.63V supply, ±50 ppm stability, -20°C to 70°C.
