The LVDS output delivers low-jitter differential signaling at 25 MHz, reducing EMI coupling into adjacent traces on a mixed-signal board.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the oscillator fits standard timing footprints. Supply voltage range is 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails without an external regulator.
Yes, the DSC1123AL2-025.0000T carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability stress tests including temperature cycling, ESD sensitivity, and latch-up immunity. This qualifies it for under-hood and chassis-domain applications where the ambient temperature reaches 105°C.
The output is LVDS — a differential, low-voltage signal that provides better noise immunity and lower EMI than single-ended CMOS outputs at 25 MHz. The LVDS pair should be routed as a 100-ohm differential pair on the PCB, with the termination resistor placed as close to the receiver as possible.
