12 MHz CMOS output from MEMS resonator
This is a standard XO (oscillator) built on a MEMS base resonator, not a quartz crystal. It outputs a 12 MHz CMOS-level clock — the 3.3V rail drives the output swing directly, so it connects to most digital logic inputs without level translation. The CMOS output is rail-to-rail, which gives clean edges into typical 10–15 pF load capacitances on a PCB trace.
±25 ppm stability and commercial temperature range
For a 12 MHz clock, this translates to a maximum frequency deviation of ±300 Hz — tight enough for UART baud-rate generation at 115200 bps without cumulative framing errors.
Standby function and low-power disable
Normal operation draws 10 mA max from the 3.3V rail. This makes it usable in battery-powered designs where the clock can be gated off during sleep — the MEMS oscillator starts up faster than a quartz crystal, typically under 5 ms, so the system can wake and clock within a single microcontroller boot sequence.
4-SMD no-lead package — board layout note
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The four pads are on the bottom — no leads to inspect after reflow. The small footprint suits space-constrained designs, but the lack of visible solder joints means X-ray inspection is the only way to confirm wetting. Standard reflow profile for lead-free assembly applies.
