MEMS XO for high-frequency clock distribution
No pin-compatible successor from Microchip is listed; the DSC1122 series as a whole is discontinued, so a board-level change to a current MEMS oscillator family (e.g., DSC1123 or DSC61xx series) may be required for volume production.
The Enable/Disable pin (tri-state output when pulled low) draws 22 mA max when disabled, useful for power-gating unused clock domains. Max supply current is 58 mA at 150 MHz LVPECL — the differential output pair drives 50-ohm terminated lines directly, so the current budget includes the load termination.
6-SMD no-lead package, 5.00 mm x 3.20 mm, seated height 0.90 mm max — standard footprint for MEMS oscillators, no via-in-pad needed. The MEMS die is hermetically sealed at the wafer level, so moisture sensitivity is typically MSL 1 (no bake required before reflow), but verify the date code on the reel.
