Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard MEMS oscillator footprint that places without tombstoning on a conventional reflow profile. No special bake required at typical MSL levels, but confirm the moisture sensitivity rating on the reel label before the oven.
The evidence does not list a DSC1121CI2 variant or its specifications. Confirm the pinout and frequency stability requirements from the respective datasheets before substituting — the DSC1121 base number shares the same MEMS core and package outline, but the suffix differences may indicate a different stability grade or output type.
Yes. The part includes an Enable/Disable function.
