MEMS oscillator for 20 MHz clocking in industrial environments
Supply voltage tolerance and power budget
Package footprint and board-level fit
Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1121BI1-020.0000 is a standard 5x3.2 mm oscillator footprint. The 0.90 mm profile clears most enclosure lids and heatsinks. Surface-mount reflow follows standard lead-free profiles — no special bake-out required for MSL 1 parts, but confirm with the latest Microchip application note for the specific VDFN land pattern.
