MEMS XO with four independent clock outputs
The DSC400-4134Q0028KE1 is a MEMS-based XO (standard oscillator) from Microchip's DSC400 series that provides four independent output frequencies from a single resonator: 100 MHz, 125 MHz, 25 MHz, and 100 MHz. Output logic is configurable as HCSL, LVCMOS, or LVDS, giving the system architect flexibility to drive a mix of clock domains — for example, a 100 MHz LVDS reference to an FPGA and a 25 MHz LVCMOS clock to a PHY — without extra level translation.
Supply range and enable/disable function
Operates from a 2.25 V to 3.6 V supply, covering the common 2.5 V and 3.3 V logic rails without a separate regulator.
Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height), the package footprint is compact enough for space-constrained PCIe cards or small-form-factor networking modules.
