It operates from a 2.25 V to 3.6 V supply rail, so it can share a 2.5 V or 3.3 V plane without a dedicated regulator. Housed in a 20-VFQFN with an exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the thermal pad should be soldered to a ground plane for heat sinking and mechanical stability. Listed as Active, the DSC400-0202Q0109KE1 is in production and suitable for new designs. No end-of-life notice or successor is recorded.","metaTitle":"DSC400-0202Q0109KE1 MEMS XO, LVPECL","metaDescription":"Active-production MEMS oscillator, dual LVPECL outputs at 153.6 MHz and 176.875 MHz, ±50 ppm stability, 2.25-3.6 V supply, 20-VFQFN.
