It operates from a 2.25V to 3.6V supply, so a single part number covers 2.5V and 3.3V clock domains without a separate LDO or voltage divider — useful when the same BOM feeds a 2.5V FPGA bank and a 3.3V Ethernet PHY. ## Temperature grade and deployment fit Frequency stability is ±50ppm across the full temperature range — adequate for 10/100/1000BASE-T Ethernet reference clocks and PCIe Gen1/2/3 common-clock architectures; for IEEE 1588 or SyncE a ±25ppm or TCXO would be required. Housed in a 7.00mm × 5.00mm 6-SMD package with an exposed pad (0.90mm seated height), the DSC1102AE1-148.5000 uses the same footprint as standard quartz oscillators in the 7×5 mm industry-standard envelope — a direct drop-in replacement for quartz-based XOs in that form factor. The exposed pad should be soldered to a ground plane for thermal dissipation; the 2.25V–3.6V supply rail requires a 100 nF decoupling capacitor within 2 mm of the VDD pin, per the recommended layout in the datasheet. The DSC1102 series is in volume production and available through independent distribution channels.","metaTitle":"DSC1102AE1-148.5000 MEMS XO 148 MHz LVPECL – Microchip","metaDescription":"DSC1102AE1-148.5000: MEMS-based XO, 148 MHz, LVPECL output, ±50ppm stability, 2.25V–3.6V supply, standby function.
