Active lifecycle status means this part is in production and suitable for new designs; no last-time-buy or obsolescence concerns on the horizon. ## Standby current and supply — sizing the power budget Active supply current is 3mA typ (max) at 3.3V — the MEMS resonator consumes less than a quartz equivalent at the same frequency, leaving headroom for other loads on the 3.3V rail. Standby current of 1µA max means the oscillator's own draw is negligible in a system that sleeps most of the time; a coin-cell-backed RTC or wake-up timer sees no meaningful drain from this clock. ## Package footprint and layout — 4-SMD no-lead Housed in a 5.00mm x 3.20mm 4-SMD no-lead package with 0.90mm seated height, this oscillator fits tight-profile assemblies and reflows with standard lead-free profiles.","metaTitle":"DSC1033BI1-020.0000 MEMS XO 20 MHz CMOS ±50ppm -40~85°C","metaDescription":"Microchip DSC1033BI1-020.0000: 20 MHz MEMS XO, CMOS output, ±50ppm stability, standby power-down, -40~85°C, 4-SMD.
