Frequency stability is held to ±10 ppm, which includes variation over temperature, supply, and aging — tight enough for a 148 MHz serial link without re-centring the PLL. ## MEMS reliability vs quartz in harsh environments The MEMS base resonator replaces a quartz crystal — no mechanical shock sensitivity, no crystal aging drift, and no start-up reliability issues in high-vibration or thermal-cycling applications. Product status is Active — no EOL notice, no NRND flag. The DSC1123 series is in ongoing production, so new designs and BOM replenishment face no immediate obsolescence risk. Availability confirmed at RFQ. ## 6-SMD package — layout and assembly note 6-SMD, no-lead exposed pad (7.00 mm x 5.00 mm footprint, 0.90 mm seated height). Surface-mount on standard FR-4 with no special reflow profile beyond the usual lead-free solder process.","metaTitle":"DSC1123AL5-148.5000 148 MHz LVDS, ±10 ppm, -40°C to 105°C","metaDescription":"Microchip DSC1123AL5-148.5000 XO (Standard) with LVDS output, ±10 ppm stability, 2.25V–3.63V supply, -40°C to 105°C.
