Dual-frequency LVPECL clock from one MEMS die
The DSC400-0202Q0108KI1T delivers two independent LVPECL output frequencies — 167.1875 MHz and 173.28125 MHz — from a single MEMS resonator, replacing two discrete oscillators on the BOM and saving board area in the 5.0 mm × 3.2 mm 20-VFQFN package. The MEMS base resonator eliminates the quartz start-up and aging drift concerns typical of crystal-based XOs; the 2.25 V to 3.6 V supply range lets it run directly from a 2.5 V or 3.3 V rail without an intermediate regulator.
