The LVPECL logic family requires DC-termination to VCC – 2V; a simple Thevenin-equivalent resistor network at the receiver input sets the bias point. Do not route this as a single-ended signal — the common-mode rejection of the differential pair is what keeps the jitter below the link budget. The supply range spans 2.25V to 3.6V, so the same part works on a 2.5V or 3.3V rail — no separate LDO needed. The LVPECL output swing scales with VCC; at 3.3V the differential swing is approximately 800 mV, at 2.5V it drops to about 600 mV. Confirm the receiver's input threshold and common-mode range at your chosen supply voltage. ## Frequency stability and temperature grade For a 364 MHz carrier, ±10 ppm translates to a maximum frequency deviation of ±3.64 kHz — well within the pull-in range of a typical SerDes CDR. The commercial temperature grade suits indoor equipment, networking gear, and test instrumentation; for outdoor or extended-temperature enclosures, a wider-range variant from the DSC1122 family would be needed. ## Active lifecycle — ordering and sourcing","metaTitle":"DSC1122CE5-364.0000 – Microchip MEMS XO, LVPECL, 364 MHz","metaDescription":"Microchip DSC1122CE5-364.0000: MEMS XO, LVPECL output, 364 MHz, ±10 ppm stability, 2.25V–3.6V supply, -20°C to +70°C, 6-SMD.
