Product details

MEMS oscillator for industrial clocking

The DSC1101CI5-032.0000 is a 32 MHz MEMS-based XO (Standard) with CMOS output — a drop-in replacement for quartz oscillators in designs that need tighter frequency stability across temperature without the ceramic resonator's drift.

Standby power-down and supply flexibility

A standby (power down) function drops supply current to 95 µA max — the oscillator stops, the output goes high-Z, and the rest of the board can sleep without the clock tree drawing 35 mA. The 2.25V to 3.6V supply range means it runs off a 3.3V or 2.5V rail without an external LDO; the 35 mA max draw at 32 MHz leaves headroom for the downstream load.

Sourced through independent distribution; quoted to order against the BOM quantity. No direct pin-compatible second source is listed, but the DSC1101 series shares the same 6-SMD footprint across frequencies — a frequency variant swap is a BOM change, not a board spin.

Frequently asked questions

What does the standby (power down) function do on this oscillator?

When the standby pin is asserted, the MEMS resonator stops and the output enters high-impedance. Supply current drops from 35 mA to 95 µA max — low enough to keep the board's sleep budget intact without a separate enable switch.

Can I replace a quartz crystal oscillator with the DSC1101CI5-032.0000?

Yes — the DSC1101 is a MEMS-based XO (Standard) that outputs a CMOS clock directly, so it replaces a quartz oscillator module in the same 6-SMD footprint. The ±10 ppm stability is tighter than most basic quartz XOs (±25 to ±50 ppm), which may improve timing margin in serial interfaces like UART or I2C.
