45.1854 MHz MEMS oscillator for commercial timing
The DSC1101CE5-045.1854T: The MEMS resonator provides faster startup and better shock/vibration tolerance than a quartz crystal oscillator. The operating temperature range is -20°C to 70°C, which suits office equipment, appliances, and indoor commercial electronics — not outdoor or under-hood environments.
Standby function and disable current
A Standby (Power Down) function pulls the output to high-impedance and drops supply current to 95 µA max — useful for battery-backed real-time clocks or power-gated subsystems where the oscillator only runs when the system is awake. Active supply current is 35 mA max — budget this into the rail's total draw.
Package and footprint for PCB layout
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max — this is a low-profile, small-footprint oscillator that fits tight board stacks and leaves room for surrounding passives. Surface-mount mounting with the 6-VDFN land pattern — the exposed pad on the underside should be soldered to a ground plane for thermal and mechanical stability, though the datasheet's recommended footprint is the final authority for stencil aperture.
Supplied in Tape & Reel — procurement quantities are reel increments; cut-tape or partial-reel availability is confirmed at RFQ.
