With an HCSL output and ±25 ppm frequency stability, this oscillator is a direct fit for PCIe reference clock applications and high-speed serial interfaces that demand low jitter. The wide supply range of 2.25 V to 3.6 V lets it run from a 2.5 V or 3.3 V rail without an external regulator, simplifying the power tree. Housed in a 14-VFQFN Exposed Pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm profile, the DSC2044FI2-H0001T requires a thermal pad on the PCB for heat sinking — the exposed paddle must be soldered to a ground plane to keep junction temperature within limits. ## Active production — sourcing through independent distribution","metaTitle":"DSC2044FI2-H0001T Microchip MEMS XO, HCSL, 100-156.25 MHz","metaDescription":"Active Microchip DSC2044FI2-H0001T XO (Standard) with HCSL output, ±25ppm stability, -40°C~85°C.
