Frequency stability is ±10 ppm, tight enough for 100BASE-TX Ethernet or USB 2.0 clocking without a separate PLL cleanup. The 6-SMD no-lead package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The no-lead land pattern is straightforward for reflow — the pads are on the bottom, so the hot-air nozzle needs a wide enough shroud to heat the whole package evenly. Product status is Active, meaning Microchip continues to manufacture and support this order code.","metaTitle":"DSC1121NE5-125.0000 MEMS Oscillator 125 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121NE5-125.0000 XO (Standard) 125 MHz CMOS output MEMS oscillator.
