2.048 MHz MEMS oscillator – AEC-Q100 graded for under-hood temps
The 2.048 MHz frequency is a standard telecom reference for T1/ framing, synchronous Ethernet, and base station clock distribution.
Supply voltage range is 1.8V to 3.3V, so the same order code works across a 1.8V FPGA bank, a 2.5V SerDes reference, or a 3.3V MCU clock input — no separate voltage variant to manage in the BOM. Standby mode with 15 µA disable current lets the oscillator serve battery-backed or ignition-switched modules where the clock is gated when the subsystem sleeps. The 4-SMD no-lead package (2.50 mm × 2.00 mm, 0.90 mm seated height) fits tight RF-shield can areas or multi-layer board edge placements.
