Maximum supply current is 35 mA when enabled and 22 mA when disabled via the Enable/Disable function — the disable mode cuts power consumption by over a third, useful for power-gated or battery-backed sections. The 6-VDFN package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm max — a low-profile, surface-mount footprint that fits under shielding cans or in tight card-edge clearance. The Enable/Disable pin lets the oscillator be gated by a GPIO or power-management IC, pulling the output to high-impedance without removing the supply rail. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121BM1-014.7456 MEMS Oscillator – 14.7456 MHz, CMOS","metaDescription":"Active Microchip DSC1121BM1-014.7456 XO: 14.7456 MHz CMOS output, ±50 ppm stability, 2.25-3.6 V supply, -55°C to 125°C.
