When enabled, the device draws 58 mA max — typical for a 156.25 MHz LVPECL driver driving a 50-ohm terminated line. Housed in a 6-SMD no-lead package measuring 5.0 mm x 3.2 mm with a seated height of 0.9 mm — a compact footprint that fits tight board layouts without requiring via-in-pad. It suits indoor networking gear, test equipment, and office electronics, but not automotive or outdoor enclosures where ambient exceeds 70°C.","metaTitle":"DSC1122BE2-156.2500T Microchip 156.25 MHz LVPECL MEMS","metaDescription":"Active XO (Standard) from Microchip Technology. 156.25 MHz LVPECL output, ±25 ppm stability, 2.25V-3.6V supply.
