MEMS resonator replaces quartz — what that means for your BOM
The DSC1121BM1-032.0000T uses a MEMS resonator instead of a quartz crystal — this makes it inherently more resistant to shock and vibration than a traditional quartz oscillator, and eliminates the quartz cold-start drift that can cause timing errors at low temperatures.
Supply voltage and output — one part covers 2.5V and 3.3V rails
The 2.25V to 3.6V supply range lets you use the same oscillator on a 2.5V FPGA bank and a 3.3V MCU without a separate regulator — the internal LDO handles the rail difference. CMOS output with Enable/Disable control: pulling the enable pin low drops supply current from 35 mA to 22 mA, which matters for battery-powered designs that can tolerate a short wake-up time.
Package and footprint — 6-SMD no-lead, 5.0 × 3.2 mm
Housed in a 6-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — this is the same footprint as many quartz oscillators, so it drops onto existing PCB layouts without a board spin.
