MEMS oscillator for 45 MHz clock generation
The DSC1033DE1-045.0000T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 45 MHz CMOS output from a 3.3V supply rail. Frequency stability is ±50 ppm, which keeps the clock edge within tight margin for a 45 MHz bus without needing an external trim capacitor. Typical supply current is 4 mA, and the standby (power-down) function drops draw to 1 µA max — useful for battery-powered designs that sleep between active windows.
