The DSC1123DI5-106.2500T: This is a 106.25 MHz LVDS oscillator from Microchip's DSC1123 family, built on a MEMS resonator instead of a quartz crystal. The LVDS output gives you a differential pair that rejects common-mode noise over longer board traces — useful when the clock has to run from one end of a PCB to a SerDes or FPGA on the other side. That keeps the edge placement tight enough for 106.25 MHz links without needing a temperature-compensated crystal oscillator.
Automotive-grade qualification for under-hood duty
It is not just a commercial XO with a wide temp range; the qualification means the MEMS die and the package are screened for the vibration and thermal shock an engine bay or transmission controller sees.
6-SMD no-lead package, 2.50 mm x 2.00 mm, 0.90 mm seated height. That is a compact footprint — the pads are on the bottom, so reflow is the only assembly method. No leads to bend, no through-hole option. The small size means you can place it close to the load, keeping the LVDS trace short and the differential impedance controlled.
This is a current production part, suitable for new designs.
