Yes — the supply voltage range is 2.25 V to 3.6 V, so a 2.5 V rail is within spec. The LVPECL output levels scale with Vdd; ensure the receiver meets the input threshold at 2.5 V.
The 'T' suffix typically denotes tape-and-reel packaging. The electrical specs — frequency, stability, output, supply range — are identical. Check the reel quantity in the datasheet.
The evidence does not explicitly list RoHS status, but Microchip's standard MEMS oscillator series (DSC1122) is typically RoHS-compliant and lead-free per EU directive 2011/65/EU. Confirm with the datasheet or your Microchip rep.
