MEMS oscillator for automotive and industrial clocking
The DSC1001CI1-004.9152T is a MEMS-based XO (standard oscillator) from Microchip's DSC1001 series, delivering a 4.9152 MHz CMOS output — a common baud-rate base for UARTs and MCU clock inputs. The supply voltage spans 1.8 V to 3.3 V, so the same part number can serve both 1.8 V and 3.3 V logic domains without a separate voltage translator on the clock line.
Standby function and power-down current
The standby (power-down) function drops supply current to 15 µA max, useful for battery-backed systems that need to gate the clock tree without a separate load switch. Active supply current is 8 mA max — typical for a MEMS oscillator at this frequency; the CMOS output swings rail-to-rail, so no external termination resistor is needed for short traces to a single load.
