A single device replaces up to four discrete oscillators, saving board space and reducing BOM line count. ## Frequency plan and stability budget The four fixed outputs are factory-programmed: Output 1 at 100 MHz, Output 2 at 125 MHz, Output 3 at 50 MHz, Output 4 at 100 MHz. Frequency stability is ±50 ppm across the -20°C to 70°C commercial temperature range, which is adequate for 1 GbE, PCIe Gen 2/3 reference clocks, and most FPGA transceiver banks that expect ±100 ppm or better. ## Supply voltage and output compatibility Operates from a single 2.25 V to 3.6 V supply rail, covering 2.5 V and 3.3 V logic families without an external regulator. The output can be configured as HCSL (for PCIe clocks), LVDS (for differential routing), or LVCMOS (for single-ended fan-out) — the same device serves multiple interface standards. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height). ## Sourcing status and procurement posture Microchip Technology supplies the DSC400 series.","metaTitle":"DSC400-4134Q0050KE1 MEMS XO – 4 Outputs, 100/125/50/100 MHz","metaDescription":"Microchip DSC400-4134Q0050KE1: MEMS XO (Standard), 4 outputs (HCSL/LVCMOS/LVDS), ±50 ppm stability, -20°C to 70°C, 20-VFQFN.
