LVPECL is the typical interface for high-speed SerDes, 10G Ethernet, and FPGA reference clocks — the 156.25 MHz frequency is a common multiple for 10GBASE-R and CPRI line rates. ## Supply range, enable/disable, and power budget Operates from a 2.25V to 3.6V supply rail, drawing 58 mA max when enabled and 22 mA max when disabled — the enable/disable function allows the oscillator to be gated off for system power savings without removing the supply.","metaTitle":"DSC1122AE2-156.2500 – Microchip MEMS XO, LVPECL, 156.25 MHz","metaDescription":"Microchip DSC1122AE2-156.2500 MEMS XO, LVPECL output, 156.25 MHz, ±25 ppm stability, -20°C to 70°C, enable/disable.
