Four clocks from one package
The DSC400-3333Q0104KE2T is a MEMS-based XO that delivers four independent LVDS clock outputs from a single 20-VFQFN package measuring 5.00 mm x 3.20 mm. Output frequencies are 125 MHz, 100 MHz, 200 MHz, and 156.25 MHz — a set that directly serves common Ethernet, PCIe, and SerDes reference clock requirements without extra PLLs or fanout buffers. The MEMS resonator replaces a quartz crystal, giving better resistance to shock and vibration and a faster startup time — useful in networking switches, industrial controllers, and test equipment where a single board may need multiple clock domains.
Supply voltage and temperature range
Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an intermediate regulator. The operating temperature range is -20°C to +70°C, which suits commercial and most indoor industrial environments — not rated for extended automotive or outdoor telecom enclosures. Frequency stability is ±25 ppm across the full temperature and supply range, tight enough for most 1 GbE and SATA reference clock jitter budgets.
Active lifecycle, no obsolescence pressure
Product status is Active per the manufacturer — no last-time-buy window, no NRND flag. The Enable/Disable function on the pinout lets the system shut down unused outputs for power savings.
