That saves a crystal or two on the BOM when a design needs separate clocks for Ethernet PHY, audio codec, and a serial interface. ## Stability and supply range for mixed-signal rails Frequency stability is ±25 ppm over the -20°C to 70°C commercial range – tight enough for a 10/100 Ethernet PHY clock without a separate VCXO. The 2.25 V to 3.6 V supply span lets it run off a 2.5 V or 3.3 V rail without an extra LDO. Product status is Active per Microchip. The 20-VFQFN exposed-pad package (5.00 mm × 3.20 mm, 0.90 mm height) requires a thermal via pattern under the paddle for proper heat transfer.","metaTitle":"DSC400-0111Q0116KE2T MEMS XO – 12.288 / 14.7456 / 11.2896","metaDescription":"Microchip DSC400-0111Q0116KE2T: triple-output MEMS XO, 12.288/14.7456/11.2896 MHz, ±25 ppm, LVCMOS, 20-QFN, active.
