It is a standard XO (oscillator) with LVCMOS output, so it drops into a 4-pin oscillator footprint without external load capacitors or a feedback resistor. The 4 MHz frequency is common for MCU clock inputs, USB low-speed, and CAN controllers — the MEMS startup is typically under 5 ms, which can shave milliseconds off the system boot sequence compared to a quartz oscillator. ## Frequency stability over the industrial temperature band Rated ±20 ppm across -40 to 85°C — that is the total frequency deviation including initial tolerance, temperature drift, and aging. For a 4 MHz carrier, ±20 ppm equals ±80 Hz maximum drift, which keeps the clock within the tolerance of most UART and SPI peripherals. In active mode the maximum supply current is 7.5 mA at 4 MHz and 1.8V — the MEMS architecture keeps the active draw comparable to a quartz oscillator while offering faster startup and better shock immunity. ## Package and layout — 4-VDFN with exposed pad The pad also provides a low-inductance ground return for the output, which helps maintain clean LVCMOS edges into the load.","metaTitle":"DSC1505AI3A-4M000000 MEMS XO 4 MHz LVCMOS ±20 ppm -","metaDescription":"DSC1505AI3A-4M000000 Microchip MEMS XO, 4 MHz LVCMOS output, ±20 ppm stability, -40 to 85°C, 1.8V, standby function.
