MEMS oscillator with CMOS output and standby
The DSC1101CE5-049.1520 is a MEMS-based XO (Standard) that outputs a 49.152 MHz CMOS clock. The MEMS resonator eliminates the quartz start-up and aging concerns — the frequency is set at the factory and does not require an external load capacitor. Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without a separate regulator. The standby (power down) function drops supply current to 95 µA max when the enable pin is pulled low.
Package, footprint, and temperature grade
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The 0.50 mm pitch pads are compatible with standard reflow profiles; no via-in-pad required for this small outline. Rated for -20°C to 70°C — a commercial temperature band suited for indoor equipment, office peripherals, and consumer audio/video gear. Not qualified for automotive or extended industrial use.
