Supply voltage spans 2.25 V to 3.6 V, so the same part number serves 2.5 V and 3.3 V clock domains without a separate LDO. ## LVPECL output — termination and AC-coupling notes LVPECL is a differential current-mode logic standard that requires a 50 Ω to VCC–2 V termination at the receiver. The 25 MHz fundamental frequency is well within the LVPECL edge-rate capability, but the DC bias must be set correctly — typically a Thévenin-equivalent divider or a dedicated termination resistor network. AC-coupling with a 0.1 µF cap in each leg is common when the receiver has its own bias network. ## Package and layout — 7.0×5.0 mm, 6-SMD, exposed pad The 6-SMD no-lead exposed pad package measures 7.0 mm × 5.0 mm with a seated height of 0.90 mm max. The 0.50 mm pad pitch on the 6-lead layout is straightforward for two-layer boards. Listed as Active by Microchip. The DSC1122 series is the standard product; no pin-compatible successor has been announced.","metaTitle":"DSC1122AE1-025.0000 Microchip MEMS XO, 25 MHz, LVPECL","metaDescription":"Microchip DSC1122AE1-025.0000 MEMS oscillator, 25 MHz LVPECL output, 2.25V–3.6V supply, ±50 ppm stability, -20°C to 70°C.
