The ±25 ppm stability over -40°C to +85°C means the oscillator holds its frequency within 0.0025% across the full industrial temperature range. For a 133 MHz clock, that is a maximum drift of about 3.3 kHz – well within the capture range of a typical Ethernet PHY or FPGA MMCM. Microchip lists the DSC1025BI2-133.0000T as Obsolete. For a BOM line that must stay active, a pin-compatible MEMS oscillator from the same package family (5.0 mm × 3.2 mm, 4-SMD) with the same 2.5V supply and CMOS output is the practical migration path. Confirm the replacement's frequency stability and standby logic polarity before respinning the board. ## Standby function and supply current – power budget fit The oscillator draws 10 mA max when enabled and 1 µA max in standby (disable) mode. The standby pin lets a battery-powered system cut the oscillator's draw to near-zero during sleep, preserving the battery for the active duty cycle. The 2.5V supply rail is common in low-power FPGA and MCU designs. If your board only has a 3.3V rail, the DSC1025BI2 cannot be used directly – it requires a 2.5V supply or an LDO to drop from 3.3V.","metaTitle":"DSC1025BI2-133.0000T MEMS Oscillator – 133 MHz, ±25 ppm","metaDescription":"Microchip DSC1025BI2-133.0000T XO (Standard) CMOS output, 2.5V, -40°C to +85°C, 133 MHz MEMS oscillator.
