22.5791 MHz MEMS clock — ±10 ppm over industrial temperature
The DSC1101CI5-022.5791: The clock stays within 10 ppm of nominal over the device lifetime, which matters for audio sample-rate clocks and serial-data links where jitter budget is tight. Supply range spans 2.25V to 3.6V, so the oscillator runs directly from a 2.5V or 3.3V rail without an intermediate LDO.
6-SMD no-lead package — 3.2 mm x 2.5 mm footprint
Housed in a 6-SMD no-lead package measuring 0.126" x 0.098" (3.20 mm x 2.50 mm) with a seated height of 0.035" (0.90 mm). No exposed thermal pad — the package relies on the board copper for heat dissipation; the 35 mA max draw keeps self-heating low, so no special thermal land is needed.
Microchip lists the DSC1101CI5-022.5791 as Active. The DSC1101 series spans a range of frequencies and stability grades; this exact order code is the ±10 ppm, 22.5791 MHz variant in the 6-SMD package.
