This means the part is inherently more shock- and vibration-tolerant than a quartz-based oscillator — a useful trait for telecom backhaul, industrial Ethernet, or any board that ships with a potting compound or sees a drop test. The -20°C to 70°C temperature range covers most indoor and outdoor telecom equipment — not rated for under-hood automotive or downhole, but fine for a base station, switch, or industrial controller. ## Package and board layout fit Housed in a 6-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The exposed pad needs a thermal via pattern under the package to pull heat into the ground plane — without it the 32 mA max supply current won't cause trouble, but the pad is the only thermal path, so a solid via cluster keeps the junction temperature well inside the commercial range. ## Enable/Disable function and power savings Includes an Enable/Disable pin that drops the supply current to 22 mA max when the output is tri-stated. Useful for power-sequenced designs or for gating the clock during a low-power sleep mode — the oscillator core stays running, but the LVDS output driver shuts off, saving 10 mA per clock.","metaTitle":"DSC1123AE2-040.0000T – Microchip 40 MHz LVDS MEMS Oscillator","metaDescription":"Microchip DSC1123AE2-040.0000T: 40 MHz LVDS XO, MEMS resonator, ±25 ppm stability, 2.25-3.63 V supply, -20 to 70 °C.

The MEMS resonator has a different failure mode (no quartz crystal to crack) and typically offers better jitter performance, but the pinout and footprint match the industry-standard 7.0 x 5.0 mm 6-pin LVDS oscillator layout.
