Supply voltage spans 2.25 V to 3.6 V, so the same part works with 2.5 V and 3.3 V rails without a separate LDO for the oscillator. Frequency stability is ±50 ppm over the full -40 to +105 °C industrial temperature range, holding the clock edge jitter within the timing budget for a 10.3125 Gbaud serial link. ## Package, footprint, and enable/disable function Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits dense PCB layouts without consuming extra board area.","metaTitle":"DSC1122CL1-156.2500 MEMS XO, LVPECL, 156.25 MHz, Active","metaDescription":"Microchip DSC1122CL1-156.2500: MEMS-based XO, LVPECL output, 156.25 MHz, ±50 ppm, -40 to +105°C, 2.25-3.6 V supply.
