MEMS oscillator with dual LVPECL outputs
The DSC400-0202Q0109KI2 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two LVPECL output frequencies: 153.6 MHz and 176.875 MHz. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails common in networking and baseband designs.
The 20-VFQFN exposed pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via pattern under the pad for heat sinking — the datasheet layout recommendation should be followed to keep the MEMS die within its operating range.
