If you need 32.768 kHz for a Real Time Clock (RTC), you are stuck with a crystal or a specialized MEMS RTC. Nothing beats quartz for low-frequency precision.
The LMK3H0102 is a "BAW" (Bulk Acoustic Wave) resonator. It is a silicon resonator that you can program via I2C to output any frequency from 1 Hz to 200 MHz. bicfic alternative new

You can drop a SiT8008 (programmable) directly onto the pads of a standard BICFIC footprint (often 2.5mm x 2.0mm or 2.0mm x 1.6mm). The difference? No quartz blank means no EMI hot spots radiating from the can lid. If you need 32
If "new" means "better reliability," MEMS wins. However, for ultra-low phase noise (radar or high-end audio), MEMS still lags slightly behind the best quartz. Alternative #2: The "Naked Crystal" + Pierce Gate (The Zero-Cost Alternative) This isn't a product; it's a topology shift. Many engineers asking for a bicfic alternative new actually don't need an integrated oscillator. They just think they do. It is a silicon resonator that you can
The latest generation, specifically the SiTime Elite Platform and the low-power SiT15xx series, solves the "jitter" problem that plagued early MEMS. These new parts offer ±5 ppm stability across -40°C to 105°C, which traditional BICFIC cannot touch.
Search for "HSE oscillator gain" or "Low-power crystal bypass." If your MCU supports "low drive" mode, you can use a cheap raw crystal. If it supports "external clock input," you can feed it a MEMS clock.
