26 MHz MEMS oscillator with full military temperature range
The DSC1121BM1-026.0000T is a 26 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±50 ppm frequency stability across the entire -55°C to 125°C range. Supply voltage spans 2.25V to 3.6V, so the same part works on 2.5V and 3.3V rails without a separate LDO — one BOM line covers mixed-voltage designs.
Enable/disable function and power-down control
Maximum supply current is 22 mA when enabled; the disable function cuts that to near zero, which is useful for battery-powered equipment or thermal management in dense boards.
6-SMD no-lead package — board layout fit
Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many 5.0 x 3.2 mm oscillator pads.
