The HCSL output swings 700 mV peak-to-peak into a 50 Ω differential pair, matching the input requirements of most Ethernet and PCIe clock receivers without external level translation. ## Industrial temperature range and standby power-down Normal operation draws 40 mA typical. ## MEMS resonator — shock and vibration advantage over quartz For designs that must survive shipping, panel-mount vibration, or downhole drilling, the MEMS construction eliminates the quartz fragility risk without changing the footprint or output. ## 6-VDFN package — board layout notes Housed in a 6-VDFN package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — the small footprint and low profile fit under heatsinks or in tight card-edge zones.","metaTitle":"DSC1204DI3-156M2500 MEMS XO 156.25 MHz HCSL Active","metaDescription":"Microchip DSC1204DI3-156M2500 MEMS XO, 156.25 MHz HCSL output, ±20 ppm stability, -40°C to 85°C, Standby (Power Down) function.

The MEMS resonator is pin-compatible with most quartz XOs in the same footprint. The key difference is the MEMS part's superior shock and vibration tolerance — it will survive environments where quartz may fail."},{"question":"Does DSC1204DI3-156M2500 have a standby function?","answer":"Yes — the function is listed as Standby (Power Down). When the enable pin is pulled low, the oscillator stops and draws 5 µA max.
