400 MHz LVPECL clock source with MEMS reliability
The DSC1122CI5-400.0000 is a 400 MHz XO (Standard) oscillator from Microchip Technology's DSC1122 series, delivering an LVPECL output that directly drives the differential clock inputs of high-speed SerDes, FPGA, and ASIC devices without external level translation. Its MEMS base resonator provides inherent immunity to the shock and vibration that can cause quartz crystals to frequency-pull or fail — a practical advantage for deployed systems in industrial or outdoor environments.
±10 ppm stability over industrial temperature range
The supply voltage range of 2.25V to 3.6V allows the oscillator to run from a common 2.5V or 3.3V rail without an additional LDO, simplifying the power tree.
Enable/Disable function for power management
6-SMD package and board integration
Housed in a 3.20 mm x 2.50 mm 6-SMD, No Lead package with a seated height of 0.90 mm, the oscillator fits tight-height-profile boards and shares a footprint common among MEMS oscillators in this frequency range.
