The LVPECL output delivers the fast edge rates and low jitter needed for high-speed SERDES, FPGA reference clocks, and 10G Ethernet PHY timing. The enable/disable function lets the system gate the clock for power savings — disable current drops to 22 mA max from the 58 mA max active draw. Frequency stability is held to ±10 ppm across the full temperature range, which keeps the clock edge within tight timing margins for a 125 MHz LVPECL link. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — relevant for equipment that ships on a truck or lives near a compressor. ## Active lifecycle and sourcing This is a current-production part suitable for both new designs and ongoing production. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1122AI5-125.0000 – Microchip 125 MHz LVPECL MEMS","metaDescription":"Active XO (Standard) from Microchip Technology. 125 MHz LVPECL output, ±10 ppm stability, -40°C to 85°C.
