LVPECL at 156.25 MHz is a common reference for high-speed serial transceivers — the differential pair needs proper termination to ground through a Thevenin network, not a simple pull-up. The wide supply range of 2.25V to 3.6V covers both 2.5V and 3.3V rails — no external regulator needed when moving between common FPGA and ASIC core voltages. ## Package and footprint for 7.0 x 5.0 mm layout The package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint shared with many 7x5 oscillators, so the PCB land pattern is well established.","metaTitle":"DSC1122AE2-156.2500T – 156.25 MHz LVPECL MEMS Oscillator","metaDescription":"Microchip DSC1122AE2-156.2500T XO, 156.25 MHz, LVPECL output, 2.25-3.6V supply, ±25 ppm stability, Enable/Disable, Active.
