The 123.52 MHz carrier with ±50 ppm stability keeps the clock edge within the jitter budget for 10GbE SerDes, FPGA transceivers, and high-speed ADC/DAC reference clocks. ## MEMS resonator and package footprint The MEMS base resonator means no quartz crystal is inside the package — the oscillator is factory-trimmed and needs no external load capacitors. The 6-SMD No Lead Exposed Pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm, a standard footprint for 7x5 mm oscillators.","metaTitle":"DSC1122AE1-123.5200 MEMS XO, 123.52 MHz LVPECL, Active","metaDescription":"Microchip DSC1122AE1-123.5200: XO (Standard), LVPECL output, 123.52 MHz, MEMS resonator, ±50 ppm, 2.25V-3.6V, -20°C to 70°C, 6-SMD.
