The DSC1121BI5-012.6500 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 12.65 MHz CMOS clock with ±10ppm stability across -40°C to +85°C.
AEC-Q100 qualification and what it guarantees
Housed in a 6-SMD, no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm, this part fits the standard 5.0x3.2mm oscillator land pattern used across the industry. The 35mA maximum supply current (22mA when disabled) keeps the thermal load low enough that no thermal pad or via stitching is required — a standard two-layer PCB layout with a 0.1µF decoupling cap at the supply pin is sufficient.
