MEMS oscillator at 2 kHz — what the ratings mean for the BOM
The DSC6021JI2A-002K: The 2 kHz frequency is unusually low for a standard oscillator — it suits applications where a precise, low-frequency clock is needed without an external divider or a separate low-frequency crystal. The MEMS resonator eliminates the startup and aging concerns of a quartz crystal at this frequency, though the part is now listed as obsolete.
Supply voltage and temperature envelope
Frequency stability is rated at ±25 ppm, which is tight enough for most UART, I2C, and SPI timing requirements.
The CMOS output is a standard logic-level signal, so no external termination or level translation is needed for most MCU or FPGA clock inputs.
Sourcing reality for an obsolete MEMS oscillator
No official successor order code is recorded in the lifecycle data. A board spin to a different oscillator may be the more sustainable path for new production.
