MEMS resonator replaces quartz — what that means for your BOM
The DSC1001CL2-022.5792 uses a MEMS resonator instead of a quartz crystal — no crystal aging, no start-up reliability issues, and a shorter lead-time profile than quartz oscillators. The base resonator is MEMS, so the frequency is set by a silicon resonator rather than a quartz blank. It is a standard XO (oscillator) with CMOS output, rated at 22.5792 MHz — the clock frequency used for audio sample rates (44.1 kHz, 48 kHz) and their multiples in audio/video equipment. Supply voltage range is 1.8V to 3.3V, so the same part covers 1.8V, 2.5V, and 3.3V logic rails without a separate voltage variant.
Temperature grade and automotive qualification
AEC-Q100 qualified — the part has passed automotive-grade reliability stress (temperature cycling, ESD, latch-up) and supports PPAP submission for automotive supply chains.
Standby function and power budget
A standby (power-down) pin disables the oscillator, dropping supply current from 6.3 mA max to 15 µA max — useful for battery-powered devices that sleep between active cycles. Frequency stability is ±25 ppm across the full temperature and voltage range — tight enough for most serial interfaces (UART, I2C, SPI) and audio clocking without external trimming.
Package and board-fit note
4-SMD no-lead package, 3.20 mm x 2.50 mm body, 0.90 mm seated height — standard footprint for automated pick-and-place; no special pad geometry beyond the datasheet land pattern.
Suitable for new designs and production builds.
