AEC-Q100 qualification and MEMS resonator
The DSC8123BI5: This makes the part a fit for engine control units, transmission modules, and ADAS sensor boards where quartz oscillators sometimes fail in field returns.
LVDS output and programmable frequency range
Output is LVDS — differential signaling that rejects common-mode noise and drives longer PCB traces or multiple clock loads with low jitter. The 32 mA max supply current is dominated by the LVDS output stage, not the MEMS core. The available frequency range spans 10 MHz to 460 MHz, and the part ships as a blank (user must program) — the buyer selects the exact output frequency via Microchip's TimeFlash programmer or factory pre-programming. Total frequency stability is ±10 ppm, tight enough for 1000BASE-T Ethernet, USB 2.0, and PCIe reference clocks without external trimming components.
