The DSC1123AI2-148.3516T: Unlike a quartz crystal oscillator, the MEMS resonator is immune to vibration-induced phase noise and has a faster start-up time — relevant for automotive and industrial applications where the clock must be stable immediately after power-on.
It suits under-hood and cabin-domain ECUs, ADAS camera modules, and infotainment systems that require a reliable reference clock.
LVDS — low-voltage differential signaling. The 148.3516 MHz clock is delivered as a differential pair, which rejects common-mode noise and keeps the signal clean over longer PCB traces or through a connector to a remote FPGA or SerDes.
The wide tolerance also helps if the supply has ripple or droop under load.
Yes, it carries an AEC-Q100 rating, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. Suitable for under-hood and cabin electronics.
