The DSC1001CI2-037.1250B is a 37.125 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm.
Standby power draw and supply flexibility
That ratio means a battery-backed ECU or sensor node can keep the oscillator quiescent and wake it on demand without draining the backup supply. The standby function is a pin-controlled power-down: pulling the enable pin low stops the output and cuts the internal bias current to the MEMS and PLL, which is how it hits that 15 µA figure.
