That replaces up to four discrete oscillators on the board, cutting placement count and routing congestion. Each output can be independently configured as HCSL or LVCMOS, so the same part feeds a PCIe reference clock and a logic-level system clock without a translator. With a supply range of 2.25 V to 3.6 V, this oscillator runs directly off a 2.5 V or 3.3 V rail without an intermediate LDO. The wide tolerance also absorbs rail ripple from a switching regulator upstream. ## Active production – no lifecycle risk for new builds The MEMS resonator construction avoids the quartz supply constraints that occasionally hit crystal-based oscillators, giving this part a more predictable lead-time profile. ## Package and layout – 20-VFQFN with exposed pad The 20-VFQFN package measures 5.00 mm × 3.20 mm with a 0.90 mm seated height.","metaTitle":"DSC400-1444Q0060KE1T MEMS Oscillator – 4-Output","metaDescription":"Microchip DSC400-1444Q0060KE1T: quad-output XO, 100MHz x3 + 25MHz, HCSL/LVCMOS, 2.25-3.6V, -20~70°C.

The supply voltage range of 2.25 V to 3.6 V includes 3.3 V, and the LVCMOS output option drives 3.3 V logic directly. The HCSL output is a differential pair typically used for PCIe and requires AC-coupling if the receiver is 3.3 V tolerant."},{"question":"What is the output frequency of the DSC400-1444Q0060KE1T?","answer":"The device provides four outputs: three at 100 MHz and one at 25 MHz.
