The MEMS resonator replaces a quartz crystal, giving better shock and vibration tolerance — useful if the board sees a drop test or lives near a motor drive. Supply voltage spans 2.25V to 3.6V, so it runs off a 2.5V or 3.3V rail without a separate regulator. The Enable/Disable function lets you gate the output for power savings in multi-clock systems. ## Frequency stability and temperature grade Rated ±10 ppm frequency stability over the full -40 to 85°C industrial range. That is tight enough for a 1 GbE SerDes reference or a FPGA transceiver clock without additional PLL cleanup. Maximum supply current is 58 mA when enabled, dropping to 22 mA in disable mode — the disable current is low enough to leave the oscillator powered on a shared rail without a load switch. Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch pads are standard for this footprint class — a two-layer board handles the fan-out, but keep the output trace short to preserve LVPECL edge rates.","metaTitle":"DSC1122CI5-048.0020 MEMS XO, LVPECL, 48.002 MHz, ±10 ppm","metaDescription":"Microchip DSC1122CI5-048.0020 MEMS XO, LVPECL output, 48.002 MHz, ±10 ppm stability, -40 to 85°C, 6-SMD.
