The CMOS output drives standard logic thresholds directly; no external termination resistor is needed for short PCB traces under 50 mm. ## Package and footprint – 5.0 mm x 3.2 mm, 4-pin, no-lead The 4-SMD, no-lead package (5.00 mm x 3.20 mm, 0.90 mm seated height) is the same land pattern as many quartz oscillators in this form factor — a direct solder-paste swap on a reflow line. ## Active production – no last-time-buy clock ticking Microchip lists the DSC1001 series as Active.","metaTitle":"DSC1001BI2-004.0000T – Microchip MEMS XO, 4 MHz, AEC-Q100","metaDescription":"DSC1001BI2-004.0000T: 4 MHz MEMS oscillator, AEC-Q100, ±25 ppm, -40°C to 85°C, 1.8V–3.3V, CMOS output with standby.
