MEMS resonator eliminates the quartz start-up delay and vibration sensitivity: the oscillator is ready within microseconds of power-up and holds ±25 ppm stability across -40°C to +85°C, which covers the full industrial temperature band without a crystal oven. ## Wide supply tolerance and standby power-down Product status is Active. 6-SMD, no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height. The 0.50 mm pitch pads require standard 0.3 mm via or microvia fan-out on a two-layer board; a ground plane under the package improves EMI margin on the LVDS pair.","metaTitle":"DSC1103CI2-166.0000T MEMS Oscillator 166 MHz LVDS Active","metaDescription":"Microchip DSC1103CI2-166.0000T XO, 166 MHz LVDS output, ±25 ppm stability, -40°C to +85°C, 6-SMD.

The 166 MHz frequency and LVDS signalling make it a direct fit for high-speed serial clock distribution without an external level translator."},{"question":"Can DSC1103CI2-166.0000T replace a standard quartz oscillator?","answer":"Functionally yes — it provides the same 166 MHz clock with LVDS output, but the MEMS resonator differs from quartz in start-up time (microseconds vs milliseconds) and vibration immunity. The 6-SMD footprint is common, but confirm the pad layout matches the existing quartz oscillator's pinout before substitution."},{"question":"What is the difference between DSC1103CI2 and DSC1103CI1?","answer":"The evidence does not list the CI1 variant.
