That frequency is a standard reference for 10GbE, Fibre Channel, and FPGA transceiver banks — the LVPECL swing provides the edge rate and common-mode range that CML and AC-coupled LVPECL receivers expect. That matters in multi-rail designs where the oscillator's draw contributes to the idle power budget. Microchip lists the DSC1122BE1-156.2500T as Active. Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The -20 to +70°C operating range covers commercial and most indoor telecom environments.","metaTitle":"DSC1122BE1-156.2500T Microchip MEMS XO, LVPECL, 156.25 MHz","metaDescription":"DSC1122BE1-156.2500T from Microchip: XO (Standard) oscillator, LVPECL output, 156.25 MHz, MEMS resonator, -20 to +70°C, 6-SMD.
