The 0.50 mm pad pitch and exposed centre pad require a four-layer board for proper LVPECL 50-Ohm controlled-impedance routing and thermal relief.","metaTitle":"DSC1122CI1-156.2500 — 156.25 MHz LVPECL MEMS Oscillator","metaDescription":"XO (Standard) MEMS oscillator, 156.25 MHz, LVPECL output, 2.25V–3.6V supply, -40°C to 85°C.

The base resonator is MEMS, not quartz. This gives better shock tolerance and faster startup compared to a crystal-based XO."},{"question":"Does DSC1122CI1-156.2500 have an enable/disable function?","answer":"Yes. The Enable/Disable function on pin 1 gates the output.
