MEMS oscillator for harsh-environment timing
The DSC1121BM2-016.0000 is a MEMS-based XO (Standard) from Microchip Technology, delivering a 16 MHz CMOS clock with ±25 ppm frequency stability across the full -55°C to 125°C military temperature range.
Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.50 mm pitch on the outer rows fans out on a two-layer board without via-in-pad; a four-layer board adds a ground plane under the part for EMI containment on the CMOS edge rates.
The DSC1121 series is the current production family; no successor has been announced. The 6-SMD MEMS oscillator footprint is shared across the DSC1121 family, so a frequency change within the series keeps the same land pattern.
