The wide input range also absorbs rail ripple — a 3.3 V rail that dips to 3.0 V under load still keeps the oscillator locked. ## Industrial temperature grade and tight stability The 6-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that leaves room for passives on a dense mixed-signal board.","metaTitle":"DSC1122CI5-074.0000T MEMS XO – 74 MHz LVPECL, ±10 ppm","metaDescription":"Microchip DSC1122CI5-074.0000T: 74 MHz MEMS XO, LVPECL output, ±10 ppm stability, 2.25-3.6 V supply, -40°C to 85°C, 6-SMD.

The MEMS resonator is a drop-in replacement for a quartz XO in the same 6-SMD footprint — no external load capacitors or bias resistors needed. The enable/disable function is a bonus that quartz oscillators often lack."},{"question":"Is DSC1122CI5-074.0000T RoHS compliant?","answer":"Yes, the part is RoHS compliant.
