Available through independent surplus distribution in lot-specific quantities; availability confirmed at RFQ. ## 27 MHz MEMS oscillator with standby mode This is a MEMS-based XO (Standard) in the DSC1033 PureSilicon™ series, delivering a 27 MHz CMOS output from a 3.3V supply. The standby (power-down) function pulls the disable current to 1µA max, making it suitable for battery-operated or duty-cycled systems where the oscillator must shut down between active periods. The 4-SMD no-lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint for space-constrained PCBs. ## Frequency stability and supply current Frequency stability is ±50ppm, which holds the clock edge within tight tolerance for UART baud-rate generation or MCU timing without external trimming. Typical supply current is 3mA max at 27 MHz, keeping the thermal contribution low in dense layouts.","metaTitle":"DSC1033DI1-027.0000T MEMS XO 27MHz CMOS Standby - Microchip","metaDescription":"DSC1033DI1-027.0000T MEMS oscillator, 27 MHz CMOS output, standby mode, -40°C~85°C.
